2 **NAL Call No.:  QP33.J681****Absorption of short-chain fatty acids across ruminal epithelium of sheep.** Kramer, T.; Michelberger, T.; Gurtler, H.; Gabel, G. *J-comp-physiol,-B-Biochem-syst-environ-physiol* v.166(4): p.262-269. (1996) Includes references.*Descriptors:* sheep; rumen-epithelium; short-chain-fatty-acids; digestive-absorption; propionic-acid; nutrient-transport; ph; sodium; hydrogen-ions; chloride; nitrate; metabolic-inhibitors; cation-exchange; anion-exchange; carbon; anions; in-vitro; bicarbonate

*Abstract*:  Investigations on the absorption of short-chain fatty acids across ruminal epithelium of sheep were performed both in vitro (Ussing chamber technique, using propionic acid representatively for short-chain fatty acids) and in vivo (washed, isolated reticulorumen). A pH-induced, nearly tenfold increase in the concentration of undissociated propionate led to an only twofold increase in mucosal-to-serosal flux of propionate (in vitro). Neither amiloride (1 mmol.l-1, in vitro) nor theophylline (10 mmol.l-1, in vivo), inhibitors of the ruminal Na+/H+ exchanger, exerted and significant influence on propionate fluxes or short-chain fatty acids absorption, respectively. Total replacement of luminal Na+ (by choline) did not alter short-chain fatty acids absorption (in vivo). Mucosal 4,4'-diisothiocyanatostilbene-2'2'-disulfonic acid (0.1 mmol.l-1) or mucosal nitrate (40 mmol.l-1) markedly reduced propionate net flux (in vitro). Increasing mucosal Cl- concentration brought about a significant drop in mucosal-to-serosal flux of propionate (in vitro) and in short-chain fatty acids net absorption (in vivo), respectively. The results obtained suggest that short-chain fatty acids are absorbed both as anions and as undissociated acids across ruminal epithelium of sheep. It is concluded that short-chain fatty acids anions either compete with Cl- for binding sites at a common anion-exchange mechanism or that they are absorbed by an short-chain fatty acids anion/HCO3(-) exchanger indirectly coupled to a Cl-/HCO3(-) exchanger via intracellular bicarbonate.

3 **NAL Call No.:  382-So12****Acacia saligna as a fodder tree for desert livestock and the interaction of its tannins with fibre fractions.** Degen, A. A.; Becker, K.; Makkar, H. P. S.; Borowy, N. *J-sci-food-agric* v.68(1): p.65-71. (1995 May) Includes references.*Descriptors:* livestock-farming; tannins; acacia-saligna; nitrogen; fiber; fodder; deserts; sheep; goats

*Abstract*:  Acacia saligna was examined as potential fodder for sheep (27.4 kg) and goats (14.8 kg) raised in arid and semi-arid areas. This leguminous tree remains green all year and can be grown in deserts using only runoff water. Phyllodes collected in March had a crude protein content of 12.5% dry matter (DM) and high tannin content (tannins as tannic acid equivalent to 11.3% and condensed tannins as leucocyanidin equivalent to 8.3% DM). DM intake was low, amounting to 0.80% and 1.05% body mass daily for sheep and goats, respectively. Sheep lost 227 g day-1 and goats 196 g day-1 while on this diet. Dry matter, organic matter and energy digestibilities were low in both species but were higher for goats than for sheep, and negative digestibilities were measured for acid detergent fibre (ADF) and acid detergent lignin (ADL). Metabolisable energy intake for goats was 121.9 kJ kg -0.75 day-1 and for sheep was 78 6 kJ kg -0.75 day-1. Apparent N digestibility was 17.5% and 0.9% for goats and sheep, respectively, and both species were in negative N balance of 0.25-0.30 g kg-0.75 day-1. Total water intake and output were higher in sheep than in goats. Extractable tannins were virtually absent in faeces in both species however, output of condensed tannins and protein in the ADF and ADL fractions were substantially higher. This showed the presence of tannin-protein complexes in these fractions which explained the negative digestibilities of ADF and ADL. It was concluded that Acacia saligna could not be used as a sole dietary source for small ruminants because of low intake and negative nitrogen balance. This was due mainly to the high tannin content. However, the tree might have a potential as a supplementary fodder due to its high crude protein content.

17 **NAL Call No.:  44.8-J822****Apparent digestibility of minerals by lactating cows from a total mixed ration supplemented with poultry litter.** Ben Ghedalia, D.; Miron, J.; Yosef, E. *J-dairy-sci* v.79(3): p.454-458. (1996 Mar.) Includes references.*Descriptors:* dairy-cows; poultry-manure; digestibility; dietary-minerals; calcium; phosphorus; magnesium; potassium; bioavailability; drinking-water; chemical-composition; intake; trace-elements; sheep; israel

*Abstract*:  Apparent digestibility of minerals by lactating cows from a multiple-component, conventional Israeli TMR (control) and from a TMR containing 10% poultry litter (DM basis) was examined. Ten cows in early lactation were divided into two groups of similar performance (39 kg of milk/d) and fed for ad libitum intake the two TMR for 28 d. Poultry litter contributed, as a percentage of total requirements, 44.4% of Ca, 41.0% of P, 32.0% of S, 22.8% of Mg, and 25.9% of K. Apparent digestibility of the macroelements was higher for cows fed the TMR supplemented with poultry litter than for those fed the control TMR. Apparent digestibility of the control TMR was 22.3% for Ca, 29.4% for Mg, 39.1% for P, and 62.2% for S; the apparent digestibility of the treatment TMR was 30.1% for Ca, 45.6% for Mg, 45.3% for P, and 65.6% for S. Poultry litter contributed the entire requirements of Zn, Mn, and Co; 56% of Cu; and 32% of Se. The apparent digestibility of the control TMR was 15.6% for Cu, 39.6% for Zn, 8.51% for Mn, 42.8% for Co, and 41.6% for Se, and the apparent digestibility of the treatment TMR was 27.9% for Cu, 54.0% for Zn, 17.8% for Mn, 37.0% for Co, and 63.9% for Se. Poultry litter is a good source of macro- and microelements for lactating cows and, at 10% of the TMR, could ensure against mineral deficiencies.

18 **NAL Call No.:  280.8-J822****Approximating farm-level returns to incremental advertising expenditure: methods and an application to the Australian meat industry.** Piggott, R. R.; Piggott, N. E.; Wright, V. E. *Am-j-agric-econ* v.77(3): p.497-511. (1995 Aug.)

*Abstract*:  Equilibrium displacement modeling is used to analyze the effects of incremental advertising expenditure by the Australian beef, lamb, and pork industries in domestic and export markets. The effects on prices, quantities traded, revenues, producer surpluses, and profits net of advertising expenditure are reported. Cross-commodity impacts of advertising are highlighted, including how one industry has to adjust its advertising expenditure to preserve profit levels in the face of increased advertising by another industry. The procedures used are useful when decisions about advertising expenditure need to be made quickly.

37 **NAL Call No.:  49-J82****Butylsoyamide protects soybean oil from ruminant biohydrogenation: effects of butylsoyamide on plasma fatty acids and nutrient digestion in sheep.** Jenkins, T. C. *J-anim-sci* v.73(3): p.818-823. (1995 Mar.) Includes references.*Descriptors:* sheep; dietary-fat; soybean-oil; amides; triacylglycerols; butylamine; rumen-digestion; protected-fat; blood-plasma; blood-lipids; feed-intake; dry-matter; digestibility; volatile-fatty-acids

*Abstract*:  Based on previous results showing partial resistance of fatty acyl amides to ruminal biohydrogenation, butylsoyamide was added to sheep diets in an attempt to increase unsaturation of plasma fatty acids. Twelve wethers averaging 34 +/- 3.2 kg BW were randomly assigned to three diets containing either no added fat (control), 5% soybean oil, or 5% butylsoyamide. Dry matter intake was greater (P < .05) for sheep fed butylsoyamide than for sheep fed soybean oil (740 and 581 g/d, respectively), but neither fat supplement differed from the control diet (680 g/d). The soybean oil supplement reduced (P < .05) total VFA concentration (59.0 and 38.7 mM) and acetate:propionate (4.10 and 2.56) in ruminal samples compared with the control diet. Butylsoyamide had no effect (P > .05) on total VFA (54.4 mM) or acetate: propionate (2.96). Total tract ADF digestibility was not affected (P > .05) by either fat supplement. Relative to the control diet, soybean oil increased (P < .05) plasma linoleic acid concentration 22% compared with a 58% increase from feeding butylsoyamide (26.7, 32.6, and 42.1% of total fatty acids, respectively). Linoleic acid concentration in plasma neutral lipids, relative to the control diet, increased 15.8% (P < .05) for soybean oil compared with 64.9% (P < .05) for butylsoyamide (31.6, 36.6, and 52.1% of total fatty acids, respectively). Converting soybean oil triglycerides to fatty acyl amides substantially reduces negative effects of the oil on ruminal fermentation and increases unsaturated fatty acids in plasma. The increase in plasma unsaturated fatty acids demonstrates at least partial resistance of fatty acyl amides to ruminal biohydrogenation and their and their digestion and absorption postruminally.

(1996 May) Includes references.*Descriptors:* calves; sheep; stunning; throat; cutting; glutamic-acid; aspartic-acid; brain; release; synergism; consciousness; animal-welfare

*Abstract*:  In calves aged two to five months, throat cutting resulted in an increase in the concentration of the amino acid neurotransmitters glutamate and aspartate in the brain. Electrical head-only stunning by itself also increased the concentrations of these two neurotransmitters. The levels induced by stunning resulted in a seizure state characterised by epileptiform-like activity in the electroencephalograph. Combing head-only stunning with throat cutting within 10 seconds of the stun had a synergistic effect upon glutamate and aspartate, increasing their concentration by a greater amount and more quickly than either procedure on its own. An irreversible loss of brain function also occurred more quickly than after throat cutting alone. The administration of glutamate and aspartate receptor antagonists before the throat cutting lengthened the time to the loss of brain function in a dose dependent manner. Similar changes were observed in sheep but they occurred much more quickly than in cattle.

*Abstract*:  Expression of the interleukin 10-encoding (IL-10) mRNA by ovine (ov-) cells, in response to mitogenic stimulation, was assessed by Northern blot and polymerase chain reaction (PCR) analyses using a human (hu) IL-10 cDNA probe and oligodeoxyribonucleotide primers based on homologous regions of the human and murine IL-10 cDNA sequences. A 31 5-bp cDNA generated by the PCR analysis was cloned and used to screen a lipopolysaccharide-stimulated alveolar ov-macrophage cDNA library. The full-length ov-cDNA sequence isolated translates to a protein of 177 amino acids (aa) with a predicted 18-aa leader sequence and molecular mass of 20165 Da. Expression in a mammalian system demonstrated that the ov-cDNA encoded a protein with the expected IL-10 biological activity. Both recombinant huIL-10 and supernatants from COS cells transfected with an expression vector containing the ovIL-10 cDNA inhibited production of IL-1 and tumour necrosis factor-x by ov-alveolar macrophages. Genomic DNA analysis indicated ovIL-10 exists as a single gene within the ov-genome.

*Abstract*:  A full-length ovine acetyl-CoA carboxylase-encoding cDNA (ACC) has been cloned from adipose tissue and completely sequenced. The open reading frame of 7041 nucleotides (nt) is highly homologous to the previously cloned human, rat, chicken, yeast and algal ACC (85, 89, 82, 54 and 54% identity, respectively). Transcript heterogeneity was found in the 5' and 3' untranslated regions (UTR) resulting in ACC transcripts in the range of 9.0 kb to 9.4 kb. Heterogeneity at the 5' end was generated by the insertion of a 47-nt sequence, resulting in transcripts with either 272 or 319 nt in the 5'-UTR. Heterogeneity at the 3' end was the result of the use of different polyadenylation signals. RNase protection analysis demonstrated that shorter transcripts containing 1635 nt predominated over longer transcripts of 2065 nt in the 3'-UTR.

*Abstract*:  A full length ovine steroid 11 beta-hydroxylase (cytochrome P-450(11 beta)) cDNA clone from a sheep adrenal cortex cDNA library was isolated. Sequence analysis indicates that this cDNA clone resembles bovine P-450(11 beta) cDNA (95% nucleotide sequence homology) more closely than rat P-450 (11 beta) cDNA (69% nucleotide sequence homology). Although the levels of nucleotide sequence homology of this cDNA clone to the rat P-450(11 beta) cDNA and the rat P-450(aldo) cDNA are similar, the putative amino acid sequence shows a closer resemblance to rat P-450(aldo) protein. Northern blot analysis shows that there are three sizes of transcript and they are expressed throughout the adrenal cortex.

*Abstract*:  Using the polymerase chain reaction (PCR) and primers based on regions of homology between the human and murine interleukin 7 (IL-7)-encoding cDNAs, we have amplified an ovine (ov) IL-7 cDNA from reverse-transcribed RNA extracted from concanavilin A (Con A)-activated ovine lymph-node cells. The nucleotide sequence of the cDNA and the predicted amino acid (aa) sequence showed significant homology to those of the human and murine molecules. The ovIL-7 cDNA encodes a 176-aa polypeptide that, based on analysis of murine IL-7, is processed to a protein of 151 aa. The cDNA was demonstrated to encode a protein with IL-7 biological activity. Supernatants from COS or CHO-K1 cells transfected with an expression vector containing the ovIL-7 cDNA were able to synergise with a suboptimal level of Con A to induce proliferation of ovine thymocytes. In addition, both supernatants were able to induce thymocyte proliferation, albeit at a reduced level, in the absence of Con A. Further experiments demonstrated that for induction of ovine thymocyte proliferation, recombinant (re)-ovIL-7 was able to synergise with re-human (h) IL-2 but not re-hIL-6 or tumor necrosis factor-alpha (re-hTNF alpha).

*Abstract*:  A cDNA for equine insulin-like growth factor I (IGF I) has been isolated by reverse transcriptase-polymerase chain reaction and subsequently sequenced. The sequenced fragment contained 465 bp including the coding regions for the signal peptide, the entire mature protein, and 4 amino acids into the E-peptide. Like its human counterpart, the mature equine IGF I peptide contains 70 amino acids and was 100% homologous between horse and man. The 49-amino-acid signal peptide had the threonine in position 26 of the human signal peptide substituted by isoleucine. The nucleotide homology across the entire clone was 96.3% between horse and man and 91.6% between horse and rat. The isolated cDNA hybridized to the same transcripts in fetal and adult tissues.

*Abstract*:  CD3 epsilon and the zeta-chain of the bovine T-cell receptor (TCR) are two invariant molecules with an important role in signal transduction via the TCR/CD3 complex. The nucleotide sequence of a bovine CD3 epsilon cDNA clone containing the complete coding sequence was determined and the deduced amino acid (aa) sequence compared to that of other species. The cytoplasmic domains of the different CD3 epsilon clearly show a higher degree of conservation than the extracellular domains. Bovine CD3 epsilon produced in Escherichia coli using different bacterial expression vectors was recognised by antibodies (Ab) directed against the intracytoplasmic domain of human CD3 epsilon. A partial bovine TCR zeta-chain cDNA was generated by the polymerase chain reaction (PCR) using primers that were based on sequences that are conserved between different species; 3' and 5' RACE-PCR were carried out to obtain the complete TCR zeta-chain cDNA sequence. A comparison of the predicted TCR zeta-chain aa sequence reveals that the GDP/GTP-binding motif, which is conserved in other species, shows marked differences in the bovine and ovine TCR zeta-chains. In contrast to CD3 epsilon, the short extracellular domain of the TCR zeta-chain is 100% conserved between the different species and the transmembrane domain also shows a high degree of identity. Ab were raised against the TCR zeta-chain, produced as a glutathione S-transferase fusion protein in E. coli, and were used in Western blot analysis to further characterise TCR zeta-chain expression in T-cells. These reagents provide valuable tools for the study of signal transduction pathways in normal and transformed bovine T-cells.

*Abstract*:  Winter wheat (Triticum aestivum L.), harvested at late milk, early dough, and hard dough stages of maturity was ensiled for nutritive comparisons. Diets were adjusted to 13% CP with a soy protein concentrate and fed to six ruminally fistulated growing steers and nine adult wethers in a repeated 3 X 3 Latin square design to study the effects of maintenance and ad libitum intakes on digestibility of different feed fractions. At both intakes, digestion values for the steers were greater than or equal to those for the sheep for all feed fractions except CP. Wethers achieved greater intake per unit of BW than steers during ad libitum intake. Voluntary OM intakes of steers only differed between the milk stage diet and the dough stage diets. At low intake, the diets containing the more mature silage were more digestible. At high intake, the OM of diet containing the early dough stage silage was most digestible. Increased intake caused a depression in digestibility of different feed fractions. The magnitude of the depression varied among diets and fractions. Data indicated that the nutritive value of diets based on whole crop wheat silage is affected by stage of maturity, animal species, and amount of intake. The assessment of the nutritive value of diets based on whole crop wheat silage should therefore be made with the animal species and at the amount of intake for which the diets are intended.

*Abstract*:  A three year study was conducted in the irrigated Sonoran Desert to compare the effect of different weed management methods in seedling alfalfa (Medicago sativa L.) on crop stand and yield. Treatments included; grazing with sheep (Ovis aries L.) when the crop was ready for the first harvest, a combination of preemergence and postemergence herbicides, postemergence herbicides only, and an untreated control where weeds were harvested with the hay. Weed management practice did not affect alfalfa yield in the first season, although the herbicide treatments reduced total forage (alfalfa plus weeds) yield compared with the grazed treatments and the untreated control. Crop density was not different between treatments. Herbicide treatments lowered forage yields at the first harvest by eliminating of weeds and because of crop injury in 2 of the 3 yr. At the third and subsequent harvests, there were no differences in forage yield for treatments. Plots were weed free after the second harvest. Lamb grazing selectivity in weedy seedling alfalfa was also quantified by analyzing esophageal extrusa. The lambs were selecting the weeds over the alfalfa as grazing progressed. This preference was consistent between lambs and plots, although there were year differences. Forage quality of the winter annual broadleaf weeds present in this study was comparable with the alfalfa. We concluded that grazing lambs are a good weed control method in seedling alfalfa during the winter grazing season in the irrigated Sonoran Desert.

(1996 Mar.) Includes references.*Descriptors:* calves; sheep; crab-waste; meal; nutritive-value; digestibility; rumen; protein-degradation; chemical-composition; feed-intake; liveweight-gain; soybean-oilmeal; rape

*Abstract*:  The nutritive value of dried shellfish waste (referred to as crab meal) produced in New Brunswick in the mid-1980s was evaluated by physical, chemical and biological assays. Typically, the crab meal was high in ash content (about 50%), consisting mainly of calcium carbonate and contained about 20% chitin, 25% crude protein (CP) and less than 2% lipid material. The meal could be separated by screening into a coarse fraction high in ash and chitin and a fine fraction lower in ash and higher in CP. Although the reactivity rate of crab meal ash was not as high as that of similar sized limestone particles (42 vs. 30.4 min for particles that passed a 500-micrometers screen but were retained on a 300-micrometers screen), it was high enough to suggest crab meal could be a useful rumen buffer. The CP of crab meal was highly resistant to degradation in the rumen in sacco. Less than 18% of the crab meal CP disappeared from bags suspended in the rumen for 24 h, compared with more than 87% for soybean meal and full-fat canola seed. The digestibility of crab meal dry matter by sheep was only 34.3 +/- 3.7%, but the CP digestibility was 69.6 +/- 4.1%. The chemical and physical attributes assayed and the results of the in sacco and sheep digestibility trials all suggest that crab meal should be a useful supplement for diets low in digestible undergraded protein. However, its inclusion in a supplement for beef calves fed legume silage resulted in lower feed consumption and rate of gain (P < 0.01). Feeding soybean meal or full-fat canola resulted in a significant increase (P < 0.01) in feed efficiency, compared with calves fed the control and crab meal supplements. It was concluded that crab meal produced in New Brunswick would be a useful supplement for beef cattle if problems of palatability could be overcome.

*Abstract*:  The activities of D-glucose transport (D-GT) and the glycolytic enzymes hexokinase (HK) and pyruvate kinase (PK), were measured in the erythrocytes of dogs, pigs, cats, horses, cattle and sheep. The erythrocytes of dogs had the highest activities of D-GT, HK and PK, significantly higher than the activities in the erythrocytes of the herbivores. The activities of D-GT and HK in cat erythrocytes were significantly lower than in those of dogs. The differences between the activities of D-GT in the erythrocytes of the different species followed the differences in activities of HK but not those in the activities of PK or in the blood glucose concentrations. It is considered that the activity of HK provides a convenient measurement of the relative rates of glucose oxidation in erythrocytes.

*Abstract*:  A mechanistic model of intake and chewing activities was developed using data from confined sheep in order to integrate the relationships between feeding behavior and digestive processes. The model consists of two interconnected submodels. The ruminal digestion submodel describes flows of nutrients and is based on differential equations to simulate the dynamic evolution of particulate matter and volatile fatty acids (VFA) in the reticulorumen. The diet is characterized by cell wall content and its potential digestibility, by the proportion of large particles (LP) retained on a 1-mm mesh sieve, and by an index of palatability. Particle comminution occurs during eating and ruminating. Intake is determined from attributes of the diet, animal live weight, and satiety status. Particulate outflow is calculated from a description of the activity of the reticulo-omasal orifice. Microbial digestion rates vary with lag phase, chemical fraction, size of particles, and ruminal pH. The VFA are aggregated into one compartment. The feeding decision submodel distinguishes among eating, ruminating, and resting. The choice among these activities is decided at each minute of simulation according to the relative values of functions of intake motivation (FMI) and of satiety (FSAT). The FMI function is based on diet palatability, energy balance, and the diurnal cycle. The FSAT function is determined by rumen load signals and energy balance. When the animal does not eat, the decision between ruminating and resting is related to the proportion of long particles in the rumen. Sensitivity analysis and validations indicate that the overall behavior of the model is adequate.

100 **NAL Call No.:  QL750.A6****Dietary habits and social interactions affect choice of feeding location by sheep.** Scott, C. B.; Provenza, F. D.; Banner, R. E. *Appl-anim-behav-sci* v.45(3/4): p.225-237. (1995 Nov.) Includes references.*Descriptors:* lambs; feeding-preferences; food-preferences; sorghum; wheat; novel-foods; foraging; avoidance-conditioning; spatial-distribution

*Abstract*:  Individuals often occur in subgroups that differ in their choice of forage and habitat, even within the same environment. Different foods occur in disparate locations and thus differences in dietary habits could provide one explanation for the formation of subgroups and their use of the environment. In addition, subgroups may form as a result of social interactions. We conducted experiments to study the effects of food preference and social interactions on choice of feeding location by lambs. In 1992, 12 lambs that had been reared together were separated into two groups of six lambs. Groups were conditioned to prefer one of two grains, either milo (Sorghum bicolor) or wheat (Triticum aestivum) by feeding milo or wheat for 14 days. Lambs were conditioned to avoid the other grain by following its ingestion with a mild dose of the toxin lithium chloride (LiCl) on 3 consecutive days. During testing, milo and wheat were placed at opposite ends of a 0.25 ha pasture. Lambs were first allowed to feed as groups consisting of three lambs that preferred milo and three lambs that preferred wheat, and then allowed to feed as groups in which one lamb preferred milo with three lambs that preferred wheat, and vice versa. Under both conditions, lambs always foraged on their preferred food, even when the locations of the foods were switched. In 1993, we repeated the study from 1992 in a larger pasture (1 ha) and without the use of LiCl. Lambs were reared in three different groups and fed either milo (Group 1), wheat (Group 2), or half of the lambs were fed milo and the other half were fed wheat (Group 3) for 4 months to condition a preference for either milo or wheat. When we combined lambs that preferred milo from Group I with lambs that preferred wheat from Group 2 to form subgroups of strangers, lambs fed in different locations. Conversely, social interactions and food preferences both affected choice of foraging location when lambs were reared together (companions). For instance, some lambs that preferred wheat grazed in the vicinity while peers ate milo, whereas lambs that preferred milo grazed in the vicinity while peers ate wheat. In other cases, one or two lambs separated from the rest of the group and ate their preferred grain. We conclude that food preference had a primary influence on choice of foraging location when lambs were reared separately (strangers) and preferred different foods. Food preferences and social interactions both influenced choice of foraging location for companions unless animals were made averse to one of the foods with LiCl, in which case dietary preferences overrode social influences.

*Abstract*:  Modulation of somatotrophic and homeorhetic hormones, along with changes in visceral mass and metabolic activity, were measured in growing lambs restricted in energy (ER) or metabolizable protein (PR) to maintain BW for 7 wk and then repleted for 2 wk. Control lambs were fed an adequate diet for 9 wk. Serum IGF-I decreased more rapidly in PR, but both ER and PR were 70% of controls by wk 7 of restriction (P < .05) and increased above controls by d 14 of repletion. Somatotropin, increased by PR, returned to control levels upon repletion (P < .05). Insulin was decreased by PR (P < .02) but was transiently elevated above controls by repletion in ER and PR at d 2 (P < .01). Serum triiodothyronine, reduced to 70% of controls by PR and ER, returned to control levels after d 6 of repletion (P < .05). Thyroxine declined gradually to 65% of controls in ER and PR (P < .07) but did not respond to repletion. By wk 7 of restriction, liver mass in ER and PR was decreased to 50% of controls (P < .05). Return of liver mass, on an empty body weight basis, occurred by d 2 of repletion (P < .01). In vitro O2 consumption per gram of liver tissue was increased to 125% of controls by ER and PR (P < .05). Calculated whole liver O2 consumption in ER and PR was 68% of controls at wk 7 of restriction (P < .10). Protein restriction had a more immediate impact on hormones but not on visceral mass or activity compared with energy restriction. Elevated IGF-I levels, as observed in previously restricted lambs, may mediate compensatory growth in ruminants.

*Abstract*:  Leafy spurge (Euphorbia esula L.) is a noxious weed on rangelands throughout the Northern Great Plains. Most of these ranges are grazed by cattle which do not use leafy spurge as forage. Although sheep graze leafy spurge, most land managers are reluctant to use sheep to control this noxious weed, which may be related to economic uncertainties regarding their profitability. The purpose of this study was to evaluate the economic feasibility of implementing a sheep enterprise to control leafy spurge on cattle ranches. The physical characteristics of a typical Northern Great Plains ranch, recommended stocking rates for cattle and sheep on native and leafy spurge-infested rangelands, and a sheep enterprise budget were developed using information from the literature. A LOTUS spreadsheet was developed to calculate returns over total costs of implementing various sheep enterprises. Annual returns from implementing sheep grazing on 520 ha of leafy spurge on a 4,905 ha ranch exceeded total costs by $4,675. Given the ownership costs and returns of our ranch, the breakeven lamb price would be $1.16 kg-1. Returns per head and per unit of land will vary with the distribution and size of a leafy spurge infestation, and sheep production costs and returns. Returns from sheep grazing were higher when leafy spurge was concentrated in fewer rather than in many pastures. Returns were positive when as little as 4% of the ranch was infested with leafy spurge. The availability and utility of our model will allow land managers to assess the feasibility of developing sheep enterprises to control leafy spurge.

122 **NAL Call No.:  QP251.A1T5****The effect of diet in late pregnancy of progesterone concentration and colostrum yield in ewes.** O'Doherty, J. V.; Crosby, T.

*Abstract*:  In the ewe, high level feeding is associated with low levels of circulating progesterone and that progesterone withdrawal is a prerequisite for lactogenesis and the onset of copious milk secretion. A total of 108 ewes was allocated to a 3 X 2 factorial experiment to determine the effect of diet on serum progesterone (P4) concentration and colostrum yield. On D 96 of pregnancy, the ewes were offered either grass silage, molassed sugar beet pulp (beet pulp) silage or grass silage supplemented with beet pulp. A ewes were given ad libitum access to silage. From D 126 of pregnancy, half the diets were supplemented with soybean meal with the aim of achieving a total crude protein intake of 220 g/ewe/day. Blood samples were taken on D 142 of pregnancy and at 1, 10 and 18 h post lambing for P4 determination. Metabolizable energy intakes (Mega Joules/ewe/day) of 9.1, 11.2 and 12.1 (SEM 0.37) and crude protein intakes (g/ewe/day) of 142.8, 167.4 and 162.0 (SEM 3.46) were recorded for grass silage, beet pulp ensiled and beet pulp supplemented silages, respectively, from D 126 to D 147 of pregnancy. Soybean meal supplementation increased the crude protein intake from 97.1 to 217.0 g/ewe/day (SEM 2.86) and Metabolisable Energy intake from 9.0 to 12.6 Mega Joules/ewe/day (SEM 0.31). Supplementation with soybean meal decreased P4 concentration (ng/ml)on D 142(p < 0.05)and at 1 h(P <0.01), 10h (P <0.01)and 18h post lambing(P < 0.01). Ewes offered grass silage had higher P4 concentrations on D 142 (P < 0.01) and at 1 h after lambing (P < 0.05) than the beet pulp-supplemented ewes. There were negative linear relationships between P4 concentration at D 142 and colostrum yield at 1 h (P < 0.01) and between P4 concentration at 1 h and colostrum yield at 1 h (P < 0.001) and total yield at 18 h (P < 0.001). In conclusion, ewes which were underfed had higher P4 concentrations at all times, and there were negative linear relationships between colostrum yield and P4 concentrations on D 142 of pregnancy and at 1 h post lambing.

124 **NAL Call No.:  41.8-R312****Effect of dietary protein on the regulation of populations of Nematodirus battus by lambs.** Israf, D. A.; Coop, R.

(1996 May) Includes references.*Descriptors:* lambs; nematodirus-battus; dietary-protein; protein-supplements; nematode-larvae; experimental-infections; nutritional-state; immunity; susceptibility; nematode-control

*Abstract*:  Two groups of seven and two groups of six lambs were offered either a complete basal ruminant diet (13.2 per cent crude protein [CP]) (groups 2 and 4) or the same diet supplemented with fish meal (18.3 per cent CP) (groups 1 and 3). Groups 1 and 2 were infected daily for seven weeks with Nematodirus battus larvae (L3) and groups 3 and 4 served as uninfected challenge controls. All the groups were treated with anthelmintic in the eighth week, challenged with a single dose of 30,000 N battus L3 one week later and killed nine days after the challenge. Although protein supplementation tended to enhance the regulation of the population of N battus in the lambs which had been infected continuously, the effect was not statistically significant. The worm burdens in both the groups of previously infected lambs were significantly reduced both in number and size (P<0.001) and they had a lower proportion of male worms than the uninfected challenge controls. The lambs could be segregated into high or low responders on the basis of their worm burdens, and there was a significant reduction in worm burdens (P<0.001) and size (P<0.01) in parallel with the lambs' responsiveness. The identification of high and low responders shows that when the dietary protein supply is adequate the predominant effect of the host on the pathogenicity of its parasites is the host's genetically-determined susceptibility.

125 **NAL Call No.:  41.8-R312****Effect of dietary protein supplementation on the development of immunity to Ostertagia circumcincta in growing lambs.** Coop, R. L.; Huntley, J. F.; Smith, W.

(1995 July) Includes references.*Descriptors:* lambs; teladorsagia-circumcincta; protein-supplements; casein; immunity; development; supplementary-feeding; feed-intake; liveweight-gain; growth-rate

*Abstract*:  Thirty four-and-a-half-month-old worm-free lambs were used to determine whether the rate of development of immunity to Ostertagia circumcincta infection in growing lambs could be influenced by the addition of a by-pass protein supplement. Sixteen lambs (groups 1 and 2) were fitted with an abomasal catheter and infected daily with 2000 O circumcincta L3 for eight weeks. Group 1 lambs received 45 g of crude protein day 1 (sodium caseinate) as a continuous infusion into the abomasum from week -1 to week 8. At week 9, groups 1 and 2, together with eight naive controls (group 3), were treated with anthelmintic and challenged one week later with 50,000 O circumcincta L3 and killed after a further 10 days. An additional six worm-free lambs provided feed intake and growth rate data. All the lambs were offered a complete ruminant ration (167 g crude protein kg-1) ad libitum. The cumulative liveweight gain of both the trickle-infected groups was less than that of the controls. The mean faecal egg counts were lower in group 1 from day 39 after infection and the mean worm burdens were significantly lower than in group 2. Total Ostertagia populations did not differ significantly between group 3 and either group 1 or 2 lambs. Early L4 stages constituted a greater percentage of the total worm population in group 1 (79.5) and group 2 (48.5) than in the challenge controls (group 3) (20.4). The trickle-infected lambs also had higher concentrations of gastric mast cell protease which correlated positively with the proportion of early L4 stages and negatively with the total worm burden. The provision of by-pass protein supplement accelerated the development of immunity to O.

128 **NAL Call No.:  QP251.A1T5****Effect of exogenous melatonin and plane of nutrition after weaning on estrous activity, endocrine status and ovulation rate in Salz ewes lambing in the seasonal anestrus.** Forcada, F.; Zarazaga, L.; Abecia, J.

(1995 May) Includes references.*Descriptors:* ewes; melatonin; blood-plasma; controlled-release; estrous-cycle; ovulation-rate; body-weight; body-condition; weaning; hormone-secretion; lh; spain

*Abstract*:  Forty-nine Spanish Salz ewes lambing in the second fortnight of March (20 March +/- 15 d) were used to determine the effects of exogenous melatonin and postweaning nutrition on endocrine status, date of first estrus and ovulation rate. Experimental design was a factorial defined by 2 postweaning planes of nutrition, 1.80 (high) and 1.35 (low) times the maintenance requirements, and treatment with a single 18-mg subcutaneous implant of melatonin (M) 32 d after lambing or no treatment control (C). Mean weaning to first estrus interval was shorter in treated than in control ewes (50.8 +/- 4.2 vs 87.6 +/- 6.3 d; P < 0.01). Considering both the treated and control animals together, the ratio between mean night and daytime plasma melatonin levels was significantly correlate with the implant insertion-first estrus interval on Day 5 (0.67; P <0.01) and Day 35 (0.63; P < 0.05) after implantation. Melatonin implants induced a significant increase of mean LH concentrations at Days 14 and 33 after implantation (P < 0.01) without any significant influence of plane of nutrition. Ovulation rate was higher for treated than control ewes the second estrus (P < 0.05). An interaction between plane of nutrition and exogenous melatonin on ovulation rate at the second cycle after weaning was detected (P < 0.01), being close to the significance in the first, fourth and fifth cycles (P < 0.1). These result suggest that exogenous melatonin in April may be an effective way of advancing the breeding season and enhancing ovulation rate associated with a low rather than a high plane of nutrition.

(1996 Apr.) Includes references.*Descriptors:* sheep; psorobia-ovis; infestation; population-density; nutritional-state; diet; fleece; damage; fleece-weight; skin; histology; australia; skin-scurf

*Abstract*:  A group of thirty-two Merino sheep infested with itch mites (Psorergates ovis) and fed a maintenance diet which imposed moderate nutritional stress had a significantly higher mite population, significantly more skin scurf, and significantly more fleece damage or derangement (P < 0.05) than a second group of thirty-two infested sheep fed a diet designed for unrestricted body weight gain and wool growth. Histologically there were no significant differences between the groups in the numbers of mast cells, neutrophils or eosinophils observed in skin sections, but sheep that had high mite counts (> 10 per 200 cm2 of skin area) in both groups, had more dermal mast cells than sheep with fewer mites irrespective of the plane of nutrition. Skin thickness and greasy fleece weight in the group maintained on the low plane of nutrition were significantly less (P < 0.05) than in the well-nourished group, reflecting the difference in protein and energy content of the two diets. Within the nutritionally stressed group, the sheep with low mite counts had a significantly lower (P < 0.05) greasy fleece weight and a shorter mean staple length than the sheep with high mite counts. There was no significant difference in greasy fleece weight between sheep with low or high mite counts in the group fed on the high plane of nutrition.

*Abstract*:  This experiment investigated the effect of intrajugular infusion of glucose on whole-body glucose metabolism and the absorption of nutrients by the portal-drained viscera of four Suffolk-cross sheep average BW 46 +/- 7 kg, fed a cereal/straw-based pelleted diet. Each sheep received by random allocation 0 (control), 1.0, or 2.0 mg of glucose kg BW-1.min-1 for 8 h infused into the jugular vein. Glucose irreversible loss rate, measured by simultaneous infusion of 6-[3H]-glucose, increased approximately stoichiometrically during glucose infusion (.51, .75, and 1.09 error mean square [EMS] .032 mmol/min for control, 1.0, and 2.0 mg of glucose infused kg BW-1.min-1, respectively). Utilization of glucose increased in portal tissues (P = 0.89) as a result of glucose infusion (.17, .18, and .33 EMS .008 mmol/ min) and was a constant proportion of glucose irreversible loss (.28). Portal blood flow was not affected by glucose infusion (overall mean 1.13 L/min EMS .034). Net portal absorption of acetate increased during glucose infusion although ruminal VFA concentrations were not affected. In contrast, net free amino acid absorption by portal-drained tissues was reduced during glucose infusion (291, 115, and 4 EMS 33,816 micromoles/min, P = .054). These results show that metabolism of nutrients across the gut wall is influenced by glucose availability to gastrointestinal tissues and affects the pattern of nutrients available to the liver and peripheral tissues.

Includes references.*Descriptors:* sheep; trypanosoma-congolense; plane-of-nutrition; trypanosomiasis; body-weight; hematocrit; anemia; carcass-composition; growth-rate; protein-content; diet; experimental-infections

*Abstract*:  The influence of nutritional level on the bodyweight, degree of anaemia and carcase composition of 24 sheep infected experimentally with Trypanosoma congolense was investigated. The infection caused a marked retardation of growth in the animals fed a low protein ration whereas the infected and control animals fed a high protein ration grew at similar rates. Both groups of infected animals developed similar degrees of anaemia but the infected group fed the high protein diet tended to sustain a higher intensity of parasitaemia than the group fed the low protein diet. The infection was also associated with low killing out percentages and a general reduction of total carcase protein, energy and fat. The decline in these carcase components was greater in the animals fed the low protein diet than in those receiving the high protein diet.

*Abstract*:  Six mature wethers (BW 72 kg) with ruminal, duodenal, and ileal cannulas were fed a control (no added soybean meal [SBM]) diet or diets containing unheated SBM or SBM roasted at 165 degrees C for 75, 150, 180, or 210 min in a 6 X 6 Latin square experiment. Concentrations of indicators of heat exposure (ADIN, ADF, NDF) in SBM increased with increasing roasting time. Duodenal flows of total N, non-bacterial N, and SBM N increased (P < .05) linearly with increased roasting time. Small intestinal (SI) digestibility (percentage entering SI) of total N and SBM N was influenced quadratically (P < .05) by roasting time; SI digestibilities were modestly increased by heating SBM to 150 min, then declined dramatically when SBM was heated for 180 and 210 min. These responses resulted in a quadratic (P < .05) increase in quantity of total and SBM N disappearing in the SI; quantities increased as SBM was heated to 150 min and remained unchanged when SBM was heated for 180 and 210 min. These responses resulted in a quadratic (P < .05) increase in quantity of total and SBM N disappearing in the SI; quantities increased as SBM was heated to 150 min and remained unchanged when SBM was heated for 180 and 210 min. Duodenal flows and SI digestibilities of total and non-bacterial amino acids (AA) and of most individual AA followed patterns similar to those observed for N. Maximum quantities of total and individual AA disappeared from the SI when wethers were fed SBM roasted at 165 degrees C for 150 min. Evaluation of the effects of heat treatment on the nutritive value of a protein source for ruminants should include considerations for both ruminal protein escape and SI availability of escaped protein and for the nature of the AA supply absorbed from the SI.

Lambs were fed one of five barley and canola meal based diets: (1) high energy, 15% CP, no fishmeal, (2) high energy, 15% CP, added fishmeal, (3) high energy, 18% CP, no fishmeal, (4) high energy, 18% CP, added fishmeal, and (5) moderate energy, 18% CP, added fishmeal. Canola meal contained 42.3% CP with a rumen degradability of 48.1%, while fishmeal contained 76.2% CP with a degradability of 15.2%. Diet 5 reduced growth rate, increased days on test, decreased feed efficiency, decreased dressing percentage, reduced internal fat and marginally decreased subcutaneous fat deposition, compared with a higher energy diet. Level of CP and protein degradability had little effect on growth and carcass characteristics. Dietary regime has limited potential to alter carcass leanness of feedlot lambs except by feeding for reduced growth rate which may increase production costs. Genetic selection and use of low input production systems may be more promising methods of improving carcass leanness.

154 **NAL Call No.:  41.8-C163****Effects of dietary cation-anion concentrations on performance and acid-base balance in growing lambs.** Fauchon, C.; Seoane, J. R.; Bernier, J. F. *Can-j-anim-sci* v.75(1): p.145-151. (1995 Mar.) Includes references.*Descriptors:* lambs; experimental-diets; ion-balance; cations; anions; balance-studies; feed-intake; liveweight-gain; digestibility; nutrients; blood-chemistry; urine; acid-base-equilibrium

*Abstract*:  Twenty-four castrated lambs (32.4 +/- 4.1 kg BW) were used to study the effect of varying dietary cation-anion concentration [C-A] on performance and acid-base balance. The diets contained approximately 100, 300, 500 and 700 mequiv Na+K-Cl kg-1 of feed. Each group of six lambs was fed one of the diets ad libitum during a 6-wk test. Increasing the [C-A] of the diets resulted in higher feed intake and higher daily gains (P < 0.01) without affecting feed efficiency. Apparent digestibility of nutrients was not affected by the dietary treatments but a negative relationship was found between intake and energy digestibility (P < 0.01). Blood pH was lower in lambs receiving the 100 [C-A] diet (P < 0.05). Blood bicarbonate and base excess increased as [C-A] in the diet increased from 300 to 700 mequiv (P < 0.05). Plasma Mg concentration decreased with increasing dietary [C-A] (P < 0.01). Urinary pH and urine volume increased as [C-A] in the diet increased (P < 0.01). The results indicate that diets containing between 500 and 700 mequiv Na+K-Cl kg-1 stimulated growth by allowing greater feed intake and greater daily gains with little effect on nutrient digestibility. Blood profile showed a systemic response to dietary changes in [C-A], but indicated that lambs were able to adapt to cation loads since the values obtained for acid-base balance were within physiological range for lambs.

Includes references.*Descriptors:* wethers; sheep-feeding; calcium-hydroxide; hydroxides; feed-intake; digestibility; rumen-fermentation; acid-base-equilibrium; metabolites; barley; magnesium-hydroxide

*Abstract*:  Eight mature wethers fitted with rumen cannulae were used in a double 4 X 4 Latin square feeding trial to study the effect of dietary alkalis on digestive physiology of sheep fed a high-barley diet. The treatments were: C = control diet composed of 17% alfalfa meal and 83% concentrate, on as-fed basis; CA = control plus 1% Ca(OH)2; MG = control plus 0.79% Mg(OH)2; CAMG = control plus 0.5% Ca(OH)2 and 0.39% Mg(OH)2. Dry matter intake averaged 1.91, 2.54, 2.79, and 2.72% of BW for diets C, CA, MG and CAMG, respectively (P < 0.01). Digestible DM intake was also affected by the treatments and averaged 0.97, 1.26, 1.35 and 1.37 kg d-1 for C, CA, MG, and CAMG diets, respectively (P < 0.01). Apparent DM digestibility was higher in sheep fed the C diet than in those fed the other diets (P < 0.03) and it was inversely related to intake (P < 0.01). Total VFA concentration was lower in sheep fed C than in those fed the hydroxides (P < 0.01). Proportions of individual VFA were not altered by the diet except for isobutyrate which was higher in sheep fed the C diet (P < 0.01). Rumen NH3-N concentration was lower in sheep fed the hydroxide-containing diets than in animals fed the control diet (P < 0.01). Plasma urea nitrogen was lower for the C diet (P < 0.01). Plasma glucose tended to be lower for the C diet than for the other diets (P < 0.06). The control diet induced a mild form of systemic acidosis as indicated by the decrease in blood pH, HCO3- and base excess (P < 0.01). Addition of Ca(OH)2 and Mg(OH)2 to the diet, alone or in combination, improved the systemic acid-base status of sheep and was associated with increased DM intake.

*Abstract*:  The effects of dietary protein and beta-agonist, (L-644,969) on mammary growth from weaning to puberty, hormone secretions, and milk yield were studied. Twelve lambs were assigned to each treatment in a 2 x 2 factorial arrangement with dietary protein at 15 or 20% and beta-agonist at 0 or 1 ppm of concentrate. Lambs were fed pelleted concentrate to achieve a target weight gain of 260 g/d. The treatment period continued for 102 d, with protein starting on d 1 and beta-agonist on d 20. Five lambs in each group were slaughtered at the end of treatment to investigate mammary growth before puberty. The remainder were maintained, and, after lambing, daily milk yield was recorded for 7 wk and ewes were then slaughtered. In prepubertal lambs, compared with control, the 20% protein diet had no effect on any variable measured in the mammary glands, whereas beta-agonist increased (P < .05) RNA:DNA ratio. In lactating ewes, the 20% protein diet enhanced mammary gland weight, parenchyma, parenchymal dry fat-free tissue (P < .05), and parenchymal fat (P < .01). The beta-agonist reduced mammary gland weight (P < .01), parenchyma, parenchymal dry fat-free tissue (P < .05), and parenchymal fat (P < .01). There was a nonsignificant trend for increased milk yield for ewes fed the 20% protein diet and decreased milk yield for beta-agonist. The beta-agonist increased somatotropin concentration, but there was no evidence that increased somatotropin concentration induced mammogenesis in lambs. In conclusion, increased dietary protein may play a role in stimulating mammogenesis in rapidly growing lambs before puberty.

162 **NAL Call No.:  49-J82****Effects of dietary supplementation of vitamin E on storage and caselife properties of lamb retail cuts.** Wulf, D. M.; Morgan, J. B.; Sanders, S. K.; Tatum, J.

Includes references.*Descriptors:* lambs; vitamin-e; vitamin-supplements; lamb-meat; meat-cuts; lipid-peroxidation; liveweight-gain; body-weight; dressing-percentage; carcass-weight; fat-thickness; color; keeping-quality; storage-life

*Abstract*:  Thirty wether lambs were randomly assigned to three treatments consisting of a control (C) and two vitamin E-supplemented treatments (VE), one fed 500 IU of vitamin E.lamb-1.d-1 (E500) and the other fed 1,000 IU of vitamin E.lamb-1.d-1(E1000). After a 56-d feeding period, lambs were slaughtered and carcass traits were evaluated. Wholesale legs and loins were vacuum-packaged, stored at 4 degrees C for 7, 14, 21, or 28 d, fabricated into retail cuts, and packaged and displayed to simulate retail industry conditions. The E1000 lambs gained less (P < .05)(kg/d; total gain) and had lower (P < .05) carcass weights than the E500 lambs. Alpha-tocopherol levels in the longissimus lumborum were higher (P < .05)(5.79 vs 3.50 microgram/g of tissue) for VE than for C; however, there was no difference in alpha-tocopherol level in longissimus lumborum between E500 and E1000. Leg retail cuts experienced greater (P < .05) lipid oxidation and received lower (P < .05) lean color scores than did loin retail cuts. Less (P < .05) lipid oxidation occurred from 1 to 7 d of display in VE retail cuts than in C retail cuts. Longer storage periods before retail display resulted in greater (P < .05) lipid oxidation at both 1 and 7 d of display and a higher (P < .05) rate of lipid oxidation during the display period. Supplementing vitamin E had the greatest effect in reducing lipid oxidation when cuts were stored for longer periods before retail display. Subjective scores for lean color and overall appearance were more (P < .05) desirable for VE cuts than for C cuts at all retail display periods. Lean discoloration scores and fat color scores for VE and C cuts were not different at 0 d of display but were more (P < .05) desirable for VE cuts during subsequent display. Supplementing vitamin E extended the caselife of lamb approximately 4 d; supplementing with 1,000 IU did little to improve storage/caselife attributes of lamb cuts beyond that achieved by supplementing 500 IU/d.

*Abstract*:  Livestock and range managers would have a powerful tool to direct utilization and modify plant communities if animals could be conditioned to eat specific foods or plants. We attempted to condition preferences for a low-quality forage through nutrient loading. Sheep were fed licorice or orange-flavored straw pellets then were gavaged with glucose or propionate (.381 Mcal, which amounted to approximately 13% of the daily maintenance energy requirement) or water. Four groups of ewes (n = 4) were arranged in a cross-blocked design such that each group received a unique energy/flavor combination: 1) propionate + licorice, 2) propionate + orange, 3) glucose + licorice, or 4) glucose + orange. On alternate days, each group received the other flavor plus water to create an internal control. At the end of 8 d of conditioning, preference for the two flavors was measured by two-choice preference tests. A second trial was conducted for 4 d in which the energy level was doubled to .762 Mcal. Low energy levels of either glucose or propionate did not create significant preferences. Propionate at the low-level caused satiety but at the high level conditioned an aversion to both flavors. This high level of propionate apparently caused malaise that was then associated with the taste of the flavors. The high level of glucose conditioned a preference. The high glucose treatment increased rumen microbial mass, the nutrients of which would have been absorbed in the lower gastrointestinal tract, and may have indirectly provided the positive nutrient feedback required to form a preference. There was a flavor preference for orange that was independent of the energy supplements.

*Abstract*:  Fifty-six mature Polypay ewes were used in two experiments to examine the effects of feeding a high-grain diet at a restricted intake on milk production and composition, lamb performance and out-of-season breeding. Ewes were fed either a high-grain diet (85% concentrate and 15% forage) or a high-forage diet. The high-forage diets were 68% forage and 32% concentrate in Experiment 1 and 80% forage and 20% concentrate in Experiment 2. Forage source was orchardgrass hay (Experiment 1) or alfalfa cubes (Experiment 2). Feed intake of the high-grain diet was restricted by 20% (compared with ewes fed high forage) so that intake of energy was similar for both dietary groups. Daily milk production was 19% higher (P < .05) in Exp. 1 and 8% higher (P < .10) in Exp. 2 for ewes fed high grain than for those fed high forage (2.71 vs 2.28 kg/d and 3.18 vs 2.95 kg/d in Exp. 1 and 2, respectively). Milk protein percentage and daily amount of milk protein were higher (P < .05) and the percentage of milk fat was lower (P < .03) for ewes fed the high-grain diet than for those fed the high-forage diet. Diet did not affect milk fat production (grams/day) or lamb growth rate. In both experiments blood insulin concentration was higher for ewes fed the high-grain diet than for those fed the high-forage diet; however, no improvements in reproductive performance were observed. Limit feeding high-grain diets is an effective alternative to forage for lactating ewes.

Includes references.*Descriptors:* ewes; lambs; dairy-wastes; bacterial-protein; diet; chemical-composition; body-weight; liveweight-gain; survival; blood-picture; dietary-minerals

*Abstract*:  Diets containing 0, 10, or 20% dried wash-water solids (WWS) from a milk processing plant were fed to 48 Hampshire crossbred ewes (average weight 58.1 kg) for 3 yr. Data were obtained on BW gains, hematology, tissue elements, and survival for ewes and BW gains, tissue elements and survival for their lambs. Ewes fed 20% WWS gained less (P < .05) BW during gestation and lactation in yr 1 and had lower BW (P < . 05) in yr 2 and 3 than those fed O or 10% WOOS. Lambs from ewes fed 20% WWS gained less (P < .05) BW in yr 2 and 3. Hematology variables of ewes, survival of ewes and survival of lambs were not affected by diet. Although WWS-containing diets contained high concentrations of Ca, P, Mn, and Fe and moderate concentrations of Mo, Mg, and Zn, diets had few effects on tissue elements in ewes and lambs. Concentrations of some tissue elements were less (P < .05) in lambs in yr 2 and 3 than in yr 1. Wash-water solids can be incorporated into ruminant diets, providing a disposal alternative that recycles and conserves nutrients. Long-term feeding posed only minor or negligible health or safety problems. Because of low energy and N availability and high ash content, WWS probably should be limited to 10% or less of conventional diets.

*Abstract*:  In Exp. 1, 39 ewe lambs (initial BW 29 +/- .1 kg) were used in a 2 X 2 factorial arrangement with two breeds (Polypay and Targhee) and two diets (high-forage and high-grain) to examine the effects of restricting intake of a high-grain diet on onset of puberty and lamb performance. The experimental diets were fed from 13 to 40 wk of age. The high-forage diet was composed of 80% alfalfa cubes and 20% supplement. The high-grain diet was 90% concentrate and 10% alfalfa cubes. Feed intake of the diets was controlled so that lambs fed the high-grain diet had the same growth rate as those fed the high-forage diet. Plasma insulin concentration was higher (P < .001) for lambs fed the high-grain diet than for those fed the high-forage diet. However, no diet effect on age at puberty was observed. In Exp. 2, 88 mature Targhee ewes were used to determine the effects of limiting intake of a high-grain diet on pregnancy and number of lambs born per ewe. Intake of the high-grain diet was restricted to achieve similar ME intake between diets. There were no diet effects on number of lambs born per ewe or subsequent lamb performance. Ewes fed the high-forage diet had a lower (P < .001) weight gain than those fed the high-grain diet. It was concluded that restricting intake of high-grain diets is an effective alternative to feeding high-forage diets for meeting the nutrient requirements of ewe lambs and gestating ewes; however, no improvements on reproductive performance were observed.

*Abstract*:  The effects of microbial inoculant and moisture content of alfalfa, stored as large round bales, on preservation and quality were examined in a 3-yr study. Alfalfa was round baled at 18, 45 and 60% moisture with 45 and 60% moisture bales stored in 23-m-long plastic tubes. At each moisture level, half the bales were treated with a microbial inoculant (Lactobacillus plantarum) during baling. All bales were weighed and sampled prior to storage (into storage) and prior to feeding (out of storage) with a core sampler. Field recovery and crude protein content of forage at 18% moisture were significantly lower than for forage at 45 and 60% moisture levels. ADF contents were decreased (P < 0.01) by moisture content in year 1, while the NDF contents were affected similarly in all the 3 yr. Storage recoveries were not affected by either moisture content or inoculant. Nutritive value of forages was evaluated, using completely randomized designs, in feeding trials with 96 steers and digestibility trials with 36 wethers. Dry matter intake by steers and nutrient digestibility in sheep were not affected (P < 0.05) by either moisture level or inoculant treatment. Feed conversion efficiencies and average daily gain of steers receiving 45 and 60% moisture forage were higher than for those fed 18% moisture forage. Results from this study indicated that harvesting alfalfa at 45 and 60% moisture as silage produced a better-quality product for steers than at 18% moisture dry hay and that treatment with microbial inoculant was not beneficial in preserving high moisture forage.

*Abstract*:  We proposed an hypothesis that ruminants attempt to select a diet that promotes high levels of feed intake by maintaining optimal ruminal conditions. Three tests of the hypothesis considered whether the diet selection of sheep given either a choice of two high energy density (ED) feeds or a choice between a high and a low ED feed is affected by 1) sodium bicarbonate inclusion (NaHCO3; 1, 2, and 4% [wt/wt]) in the high [ED] feed); 2) dietary carbohydrate source (barley-based, B and sugar beet/ barley, S) of the high ED feed; or 3) physical form (alfalfa: pelleted, ALFP and long chop, ALFL) of the low ED feed. To conduct these, 42 lambs were used in seven 6 x 6 Latin squares, which were either foods ALFL and ALFP offered alone and paired with feed B or S and their NaHCO3 derivatives as a choice, or foods B and S offered alone and paired with their NaHCO3 derivatives as a choice. Each Latin square period lasted for 3 wk. For the choices between a NaHCO3-supplemented high ED feed and either a high or a low ED one, the inclusion of NaHCO3 increased feed intake. Its level of inclusion had a marked effect on the proportion of unsupplemented high ED feed selected (P < .05) but not on the proportion of low ED feed (alfalfa) selected. More alfalfa was selected when the high ED feed was based on barley (B) rather than sugar beet/barley (S) (P < .05). The physical form of the alfalfa affected diet selection because its selection was greater (P < .001) when ALFP (pelleted) was offered in the feed choice rather than ALFL (long-chop). The significant effects of NaHCO3 level, dietary carbohydrate, and physical form on the diet selection and feed intake of the sheep are consistent with the proposed experimental hypothesis.

*Abstract*:  Crossbred lambs (47.3 kg BW) were used to study the effects of restraint and isolation stress on endocrine status and blood metabolites, antemortem glycogenolysis, and incidence of the dark-cutting condition (DCC) in the longissimus muscle (LM) and to determine the role of muscle contraction in the formation of the DCC in sheep. Lambs were assigned randomly to three treatments: unstressed controls (C); a single 6-h period of restraint and isolation stress (RIS); and a single 6-h period of RIS following epidural blockade (RISEB) with lidocaine. Blood was collected immediately before lambs were subjected to RIS and RISEB and at 12-min intervals during the 6-h period. Serum concentrations of glucose, lactate, and insulin were higher (P < .01 ) in RIS and RISEB lambs than in C lambs. Serum free fatty acid concentrations were higher (P < .01 ) in stressed lambs only during the first 4 h of stress. Plasma epinephrine and cortisol concentrations also were higher ( P < .01) in RIS and RISEB lambs than in C lambs. Lambs were slaughtered within 30 min after completion of stress. Immediately after stunning and at .75. 3, 6, 12, and 24 h postmortem, samples were removed from the LM in the hindsaddle and foresaddle for glycogen, lactate, and pH determinations. Muscle pH was elevated (P < .01) by RIS and RISEB; ultimate pH exceeded 6.0. The LM from carcasses of RIS and RISEB lambs had lower (P < .01) glycogen and lactate concentrations in both regions than the LM of C lambs. Subjecting sheep to a single 6-h period of RIS was an effective animal model to induce the DCC. Failure of the epidural blockade to inhibit antemortem glycogen metabolism and formation of the DCC indicates that muscle contraction was not requisite to those processes in sheep.

*Abstract*:  We studied a unique group of rams that would not mate with estrous ewes during extensive testing for sexual behavior. The same rams courted males in preference to females in 30-min sexual preference tests and were classified as male-oriented (n = 6). We compared the following endocrine profiles: systemic steroid concentrations, the capacity of the testes to biosynthesize 17alpha-hydroxyprogesterone and testosterone from 3H-progesterone in vitro, and the levels of brain aromatase activity (AA) in male-oriented rams vs. rams that were proven breeders and designated as female-oriented (n = 7). After the last behavioral test, sera were collected, and males in each experimental group were killed. Brains and testes were obtained for subsequent determinations of AA and measurements of steroidogenic enzyme activity. All dissections and subsequent assays were performed without knowledge of experimental group assignments. Serum concentration of testosterone (T), dihydrotestosterone (DHT), androstenedione, estrone (E1), and estradiol-17beta (E2) were determined by RIA. AA was quantified by a 3H2O assay validated for neural tissue of the ram. We studied frontal, parietal and cingulate cortex, cerebellum, hippocampus, olfactory bulb, septum, amygdala, infundibulum-median eminence, and preoptic area (POA). Serum T, E1, and E2 concentrations of female-oriented subjects were significantly higher (p < 0.05) than those in ma  le-oriented subjects (SEM: 1559 +/- 228, 46 +/- 2, and 15 +/- 3 pg/ml vs. 874 +/- 196, 40 +/- 2, and 8 +/- 1 pg/ml serum, respectively). DHT and androstenedione concentrations in the systemic circulation did not differ between groups. Likewise, biosynthesis of labeled T and 17alpha-hydroxyprogesterone from 3H-progesterone by testicular homogenates in vitro was significantly higher (p < 0.05) in female-oriented than in male-oriented subjects (28.8 +/- 8.1 vs. 12.1 +/-   2.3 micromole.h-1.mg protein-1 for T and 416.9 +/- 100.8 vs. 186.3 +/- 30.7 micromole.h-1.mg protein-1 for 17alpha-hydroxyprogesterone). The highest level of AA was found in the POA, which was significantly greater in female-oriented than in male-oriented rams (472 +/- 34 vs. 296 +/- 24 fmol 3H2O.h-1.mg protein-1, p < 0.05). AA in other brain areas did not differ between experimental groups. Our data suggest that the testes of the male-oriented ram have reduced capacity for T production. In other species, T controls in situ estrogen formation not only by providing substrate for aromatization but also by up-regulating P450arom mRNA in the POA. Because the POA is part of a neural circuitry that mediates male sexual behavior in many species, we hypothesize that the capacity for aromatization influences sexual orientation of these rams.

*Abstract*:  A model of producer behavior, which explicitly accounts for both output price and production uncertainty, is formulated and estimated. If the production technology is multiplicatively separable in its deterministic and stochastic components, then the expected utility maximization problem implies cost minimization for planned or expected output. Consequently, our empirical model of three lamb- and wool- producing sectors in Australia involves the estimation of a system of input cost share and cost equations whose disturbances have an error-components structure. The empirical results are evaluated in terms of input demand elasticities, and estimates of the stochastic components of production are presented.

Includes references.*Descriptors:* sheep; cattle; andropogon-gerardii; botanical-composition; infrared-spectroscopy; grasses; diet; digesta; esophagus; sampling; forbs; oklahoma

*Abstract*:  The objective of this study was to evaluate the potential of near infrared reflectance spectroscopy (NIRS) for estimating botanical composition of esophageal extrusa samples. Spectral data were collected on 361 samples from fistulated sheep and cattle grazing native tallgrass range. Principal components analysis was used to identify a subset of 73 samples with spectral dissimilarity. These samples were microhistologically analyzed to determine botanical composition and were considered 'actual' for regression and calibration purposes. Thirty-six species (12 grasses, 22 forbs, and 2 sedges) were identified in the microhistologically analyzed samples. However, most accounted for less than 5% of the total diet. Additional pure calibration samples were obtained by feeding individual species to confined fistulated sheep. Initial regression analyses and predictions were made on 13 major species or species groups. Satisfactory prediction equations could only be developed for big bluestem andropogon gerardii Vitman) (r2 =0.61), and the total grasses (r2= 0.79) and total forbs (r2 = 0.79) groups. Addition of spectra from pure samples into the calibration set was beneficial. In general, valid predictions could not be made for individual species that constituted less than 10% of the sample and/or had a low frequency of occurrence in the calibration samples. The NIRS method offered acceptable precision and accuracy in the prediction of major botanical components and it would be practical and efficient because it reduces the number of samples that would have to be microhistologically analyzed.

*Abstract*:  Prior influence of estrogen is required for many physiological effects of steroid hormones. This study addresses positive autoregulation of estrogen receptor gene expression in endometrium. Groups of ovariectomized ewes (n = 6) were treated with a single i.m. injection of 50 pg 17 beta-estradiol for 6, 12, 24, or 48 h or of vehicle for 24 h (control) prior to collection of endometrium. Three ewes received a regimen of estradiol-progesterone-estradiol (EPE) designed to mimic the estrous cycle. Northern analysis of endometrial RNA using an ovine estrogen receptor complementary RNA probe indicated that estradiol increased (p < 0.0001) estrogen receptor messenger RNA abundance over time to be 5-fold greater at 24 h postinjection. This effect also occurred after a period of progesterone dominance in EPE ewes (p < 0.05). Ribonuclease protection assays with a complementary RNA probe for the ovine progesterone receptor demonstrated that estradiol treatment increased progesterone receptor messenger RNA abundance at 48 h (p < 0.005). Nuclear runoff analyses indicated that whereas estradiol enhanced the transcription rates of progesterone receptor (p < 0.1) and 28S ribosomal RNA genes (p < 0.002), activity of the estrogen receptor gene was unchanged (p > 0.25). These results suggest that a physiological dose of estradiol, similar to the preovulatory surge of estrogen, up-regulates endometrial estrogen receptor gene expression by a posttranscriptional mechanism.

*Abstract*:  The reported cDNA sequences for the bovine (Bos taurus) and ovine (Ovis aries) alpha(s1)-caseins display a high degree of identity with the exception that a 24 bp region, corresponding to bovine exon 16, is absent in the ovine sequence. Here we show that the ovine gene for alpha (s1)-casein contains a sequence block displaying 23/24 identity to bovine exon 16, indicating that the absence of this block from ovine mRNA is due not to genomic deletion but to exon skipping. Analysis of the products obtained by reverse transcription of ovine alpha(s1)-casein mRNA followed by amplification, demonstrated the presence of mRNA species containing the exon 16 sequence as well as the species in which it had been spliced out. It was estimated that the latter constitutes 20% of the total ovine alpha(s1)-casein mRNA. We propose that a substitution within the donor splice site is responsible for the partial skipping of exon 16, possibly through the formation of an inhibitory RNA secondary structure.

*Abstract*:  To mitigate chronic shortage of feeds for livestock in developing countries, neem seed kernel cake (34-40% CP, bitter in taste, unsuitable for livestock feeding) was waterwashed (WWNSKC) and fed to 5-6-month-old male, growing goats for 180 days as a major source of protein by incorporating it at 15% (group II) and 25% (group III) in the concentrate mixtures. Their performance was compared with goats fed 15% deoiled mustard (Brassica sp.) cake (group I). CP content of group I, II and III concentrate mixtures was 16.7, 15.9 and 17.8%, respectively. Average daily DMI (g), BW gain (g/d) and feed conversion efficiency (unit DM intake/unit gain) on group I, II and III diets were 307.3 +/- 23.27, 324.0 +/- 26.78 and 325.6 +/- 25.57; 22.6 +/- 3.64, 28.9 +/- 3.34 and 25.2 +/- 2.89; 14.6 +/- 1.68, 11.4 +/- 0.63 and 13.1 +/- 0.62, respectively. Goats on all diets digested most nutrients similarly and were on positive N, Ca and P balance. Lowered total as well as NH3-N levels in rumen liquor of WWNSKC-fed goats due to residual neem bitters was indicative of passage of more by-pass protein for digestion in the lower gut. Intake of protein and energy increased linearly with level of WWNSKC incorporation and was within stipulated NRC standards. Among blood and plasma constituents, glucose (P < 0.01) (maybe because of residual neem bitters which exert antihyperglycemic effects), urea-N (P < 0.01) and total protein (P < 0.05) were lower in both experimental groups. Rumen fermentation pattern, urinary creatine and creatinine were comparable among the groups. Thus, WWNSKC can be incorporated in diets of growing goats up to 25% without deleterious effects on nutrient utilisation and metabolism.

(1996 Oct.) Includes references.*Descriptors:* lambs; feeding-preferences; barley; alfalfa-meal; novel-foods; wheat; pelleted-feeds; unrestricted-feeding; feed-intake; flavor; nutrient-requirements; aversions; rabbit-pellets

*Abstract*:  Ruminants eat a variety of foods, varying in toxins and nutrients, but no hypotheses adequately explain this behavior. We offer an explanation, one which encompasses avoidance of toxins and acquisition of nutrients. A key concept in this hypothesis is aversion, the decrease in preference for food just eaten as a result of sensory input (taste, odor, texture, i.e., a food's flavor) and postingestive effects (of toxins and nutrients on chemo-, osmo-, and mechano-receptors) unique to each food. On the basis of this hypothesis, we predicted lambs would prefer familiar and novel foods that complemented the macronutrient composition of their basal diet. To assess the validity of this prediction, we fed 10 lambs in each of three treatments different levels of ground barley (high in energy) and alfalfa (high in protein) as a basal diet. We then offered them daily a meal of three ground foods differing in proportions of barley and alfalfa (familiar foods) or wheat and rabbit pellets (novel foods). We found that lambs fed a basal diet high in energy (barley) preferred food lower in energy and higher in protein (alfalfa); those fed a diet high in alfalfa preferred food high in barley (P < .01). In addition, the higher the barley or alfalfa content of the basal diet, the greater the acceptance of novel foods high in alfalfa (i.e., rabbit pellets) or grain (i.e., wheat), respectively (P < .01). All lambs preferred foods high in wheat to rabbit pellets or alfalfa (P < 0.01), evidently because wheat is high in energy and it differs in flavor from barley, which was eaten repeatedly as part of the basal diet. On the basis of these results, we contend that lambs preferred familiar and novel foods that complemented the flavors and macro-nutrient contents of their basal diet.

*Abstract*:  We have isolated four lambda clones, which, in their aggregate, contain the entire coding sequence of the ovine gene encoding the gonadotropin-releasing hormone (GnRH) receptor (GnRHR). Like its human and murine counterparts, ovine GnRHR exists as a single-copy gene and is comprised of three exons and two introns. Furthermore, the locations of all exon-intron boundaries are perfectly conserved among the human, ovine and murine genes. The most striking difference among these genes is the location of the transcription start points (tsp) and, thus, the length of 5' untranslated region (UTR). This variation in size of the 5' UTR between the murine, human and ovine genes raises the possibility that different mechanisms have evolved for cell-specific expression of this gene. Isolation of the ovine GnRHR and its associated 5' flanking region is the essential first step in defining the molecular mechanisms underlying cell-specific and hormonal regulation of its expression in ruminants.

268 **NAL Call No.:  QL750.A6****Heterosexual experience differentially affects the expression of sexual behavior in 6- and 8-month-old ram lambs.** Price, E. O.; Borgwardt, R.; Dally, M.

*Abstract*:  The sexual performance of 6- and 8-month-old ram lambs (175 and 26 subjects, respectively) was quantified when individually exposed to four estrous ewes for 30 min on four occasions 7 days apart. In addition, half of the animals in each age class (experimental subjects) were exposed to 16 estrous females for 6, 16 or 24 h after testing on Test Days 1, 2 and 3. Control subjects received no additional exposure to females. Sexual performance improved for all groups over the 4 weeks of testing. However, 6-month control rams improved at a slower rate than 6-month experimental rams. By the fourth weekly test, 58% of the control rams and 85% of the experimental rams had attained ejaculatory competence. Treatment did not affect the sexual performance of the 8-month-old subjects; both control and experimental groups had attained 100% ejaculatory competence by the fourth week. Length of the extended exposure to females did not affect the results. It was concluded that the sexual responsiveness of ram lambs toward females is sufficiently undeveloped at 6 months (i.e. puberty) that extended exposure to sexually receptive ewes is needed for many males to exhibit adult levels of sexual performance. At 8 months, the sexual development of ram lambs has sufficiently matured so that relatively brief encounters with estrous females releases the full expression of adult sexual behaviors. These findings may be of benefit to sheep breeders who wish to use ram lambs in their breeding programs.

*Abstract*:  A controlled study was carried out to investigate the physiological effects of road transport on sheep. Animals (n = 10; body weight 38.9 +/- 1.3 kg), previously with catheters in their jugular veins, were rounded up and loaded onto a vehicle where they were held in a communal pen with eight other lambs. Blood samples were taken at 30 min intervals during the next 15 h while the vehicle remained stationary or was driven a distance of 548 miles (876 km). Measurements were made of plasma concentrations of cortisol, prolactin, creatine phosphokinase and lactase dehydrogenase isozymes and also of plasma osmolality, haematocrit and body weight; heart rate was also recorded in one animal. Loading and the start of driving produced large increases in cortisol and prolactin concentrations. Heart rate also increased whereas osmolality and haematocrit decreased. The major changes in hormone release occurred in the first 3 h period while, during the remaining 12 h, the stimulatory effect of transport was present but small. Body weight loss was similar under both stationary and driven conditions.

*Abstract*:  Small proline-rich (SPRR) proteins are markers frequently associated with squamous cell differentiation. They have been proposed to be a novel group of precursor polypeptides for the cornified envelope in epidermal keratinocytes. A plus/minus screening procedure was used to identify cDNA clones expressed in mature but not in neonatal sheep ruminal epithelium. Two clones encoding SPRR proteins were identified and are reported here. Clone 27 encodes an ovine SPRR protein corresponding to the human type-II SPRR protein. Clone 26 encodes an ovine SPRR protein similar to human type-II SPRR protein, but which also contains an N-terminal His-Pro repeat similar to the paired repeats found in the Drosophila paired proteins. The unique combination of a paired domain and an SPRR protein has not been reported prior to this study. The tissue distribution indicates that specific expression of the genes corresponding to these two clones occurs in the epithelium of the ruminant forestomach, and to a lesser extent in skin epithelium. In situ hybridization demonstrated that the SPRR mRNA for both clones were localized in the stratum granulosum, in support of their putative physiological function, i.e. formation of the cornified envelope. Based on Northern blot analysis, mRNA complementary the two clones appears in the ruminal epithelium by 1 week of age, corresponding to the formation of the stratum granulosum during ruminal epithelial development. The different patterns of changes in amount of mRNA corresponding to these clones during rumen epithelial development indicate that they play different roles in rumen epithelial development.

*Abstract*:  Lambs typically display behavioral and physiological indicants of distress when they are removed from their mother. In the present experiment, we assessed the effects of the presence of agemate conspecifics on the rate of distress bleating by 3-week-old lambs immediately following maternal separation. When removed from their mother and tested in isolation, lambs emitted more distress bleats than they did when paired with a social partner--either their twin (P < 0.01) or an unfamiliar lamb (P<0.05). Moreover, rates of distress bleating by paired unfamiliar lambs were greater than for familiar twins tested together (P < 0.02). The presence of an agemate lamb therefore appears to alleviate, at least to some extent, the stress associated with maternal separation. Lower rates of bleating by twin pairs in contrast with paired unfamiliar lambs suggest that twins recognize one another. Prior to testing, twins interacted closely and thereby had the opportunity to become mutually acquainted.

*Abstract*:  Twenty-four Suffolk lambs (average BW 38 +/- 2.7 kg; 16 ewes and 8 wethers) were fed either a corn-cottonseed hull-based control diet (CON) or CON plus 250 ppb of Cr as chromium tripicolinate (CrPic). Lambs were penned in groups of three and ADG and DMI were measured through d 85 of the experiment. Jugular blood samples were obtained during wk 2, 7, and 11. An i.v. glucose tolerance test (IVGTT; 500 mg of glucose/kg BW) and an i.v. insulin challenge test (IVICT; .1 IU of ovine insulin/kg BW) were performed during wk 2 and 10 of the trial. This was followed by a N balance trial during wk 3 and 11. Wethers were slaughtered at the end of the experiment and carcass characteristics determined. No differences (P > .10) were observed between dietary treatments in DMI, ADG, or N balance; however, the CrPic-fed wethers had 18% less fat over the 10th rib (P = .082) and a lower yield grade ( P = .014). Plasma NEFA was lower throughout the trial (P < .03) and cholesterol was 17% lower during wk 2 (P < .02) in lambs fed CrPic. There were no differences due to diet (P > .10) in plasma concentrations of urea N, glucose, albumin, total protein, insulin, glucagon, triiodothyronine, or thyroxine. Glucose clearance rate and half-life during the IVGTT and IVICT did not differ (P > .10) between CON and CrPic groups; however, during the IVGTT on wk 2, plasma insulin was elevated (P < .05) and glucose reduced (P = .067) in the lambs fed CrPic. Supplemental CrPic seems to influence metabolic measurements that may affect performance of growing lambs.

Includes references.*Descriptors:* lolium-multiflorum; nitrogen-fertilizers; lambs; diet; chemical-composition; defoliation; harvesting-date; rumen-fermentation; ammonia; louisiana

*Abstract*:  Two experiments were conducted to determine the seasonal effects of N fertilizer (NF) and defoliation interval (DI) on specific N fractions within annual ryegrass (AR) and overall usage of AR N by growing lambs. In Exp. 1. NF (0, 112, 224, and 336 kg of N/ha) and DI of 2, 4, or 6 wk were factorially applied to AR plots. Both decreasing DI and increasing NF increased N levels in AR in a manner that depended on harvest date (NF or DI X harvest date interaction, P < .05). The proportions of .2% NaOH soluble N or soluble protein N were not affected (P > .05) by NF or DI. Although NF had no effect (P > .05 ) on in situ disappearance of DM, decreasing the DI seemed to reduce the severity of the season-induced reduction in DM disappearance (DI X harvest date interaction, P = .04). In Exp. 2, NF (0 or 224 kg of N/ ha) and a DI of 2 or 6 wk were factorially applied to AR plots. Fresh, frozen AR was fed in semipurified diets (48% of DM as AR) to four wether lambs (23 + 1.3 kg) using a 4 X 4 Latin square. Diets including AR had greater ruminal DM and plant N digestibilities when AR had a 2-wk vs a 6-wk DI with NF but had reduced digestibilities when AR had a 2-wk vs a 6-wk DI without NF. Lambs retained more N when fed diets with fertilized vs unfertilized AR (P = .01) and when fed diets with AR harvested every 2 wk vs every 6 wk (P = .08). Data suggested that forage management scheme and advancing plant maturity affected ryegrass N distribution and ruminal usage in manners that had only minor consequences relative to animal performance.

298 **NAL Call No.:  44.8-J822****Influence of prepartum protein and energy concentrations for dairy goats during pregnancy and early lactation.** Sahlu, T.; Hart, S.

*Abstract*:  Sixty-three multiparous Alpine does were blocked by pregnancy type (single vs. multiple) on d 90 of pregnancy and assigned to one of nine diets to evaluate the interaction of prepartum protein and energy intake on BW change, kidding, and subsequent production and composition of milk. Treatments were factorial with three percentages of CP (8.5, 11.5, and 14.5% of DM) and three concentrations of metabolizable energy (1.80, 2.16, and 2.53 Mcal/kg of DM). Does were fed for ad libitum intake during pregnancy and switched to a lactation diet (16% CP and 2.35 Mcal of metabolizable energy/kg of DM) after parturition. Milk production and composition were recorded for the first 15 wk of lactation. Prepartum BW gain increased quadratically as protein amount increased but was unaffected by energy. Kidding rate, litter weight, and gestation length were unaffected by protein or energy amounts. Milk production in the subsequent lactation increased quadratically in response to prepartum CP (2.59, 3.26, and 3.07 kg/d for 8.5, 11.5, and 14.5% CP, respectively). Milk production increased linearly in response to prepartum metabolizable energy concentration (2.63, 3.05, and 3.26 kg/d for 1.80, 2.16, and 2.53 Mcal/kg of DM, respectively). Milk fat percentage increased linearly in response to increased prepartum energy. Production of milk fat, protein, SNF, FCM, and SCM were affected quadratically by increased prepartum CP and linearly by prepartum energy, following the pattern for milk production. The present recommendations for prepartum CP and energy appear to be adequate for gestation and subsequent lactation performance of dairy goats.

*Abstract*:  The influence of dietary protein supplementation on resistance to haemonchosis was examined in Hampshire down lambs fed either a basal diet or a diet supplemented with soyabean. At seven months of age the lambs were challenged with an initial loading dose of Haemonchus contortus. followed by a trickle infection three times a week. Blood and faecal samples were collected three times a week and bodyweights were recorded weekly. After 10 weeks the lambs were slaughtered and their worm burdens and carcase composition determined. Although their mean worm burdens were similar, the lambs given the basal diet had higher faecal egg counts, lower packed red cell volumes and lower concentrations of total plasma protein and plasma albumin than the lambs given the supplemented diet. The dietary supplementation also improved the carcase composition of the lambs.

*Abstract*:  The effect of ensiling barley treated with two bacterial inoculants containing mixtures of Lactobacillus plantarum and Enterococcus faecium (1.0 X 10(5) cfu g-1 as fed silage) on the nutritional value and aerobic stability of barley silage was examined. Inoculants differed in the strains they contained and were originally selected by Pioneer Hi-Bred International for use with corn or alfalfa silage, SILA-BAC (1174), or with grass silage (X2637). Concentrations of water-soluble carbohydrates were higher (P < 0.05) in inoculated than in control silages. Although inoculants appeared to increase the numbers of lactic acid producing bacteria (LAB) at ensiling, post-ensiling numbers (cfu g-1) of yeasts and molds were lower (P < 0.05) in inoculated than in control silages. Lactic acid concentrations and pH were similar among the silages and variations in the growth of yeast and mold populations could not be explained by differences in the production of volatile fatty acids (VFA) among silages. Inoculation of barley silage with either inoculant increased (P < 0.01) the average daily gain of lambs. A digestibility experiment with 12 growing ram lambs showed that inoculants did not alter (P > 0.05) DM intake, feed efficiency or the digestion of DM, organic matter, acid detergent fiber (ADF) and neutral detergent fiber (NDF). Nitrogen intake and retention were greater (P < 0.05) in lambs fed silage inoculated with 1174 as compared with control silage. Yeast populations were increased (P < 0.05) in control and 1174 after 2 d of exposure to air but it required 13 d for a similar yeast population to be established in X2637 silage. Increases in the mold populations within the silages were noted after 2, 5 and 13 d of exposure to air for control, 1174 and X2637, respectively. The temperature of control silage increased (P < 0.05) 2 d after exposure to air, whereas increases in temperature were delayed for 4 d in 1174 and 8 d in X2637. Temperatures rose as high as 30 degrees C in control silage, but did not exceed 24 degrees C in inoculated silages during the 13 d period.

*Abstract*:  To identify genes involved in the postnatal development of sheep ruminal epithelium, a lambdagt22a cDNA library was constructed from poly(A)+ RNA isolated from mature sheep ruminal epithelium. A plus/minus screening procedure was used to identify genes expressed in mature but not in neonatal ruminal epithelium. One of the cDNA clones isolated encodes an ovine carbonic anhydrase, based on nucleotide and deduced peptide sequence analysis. The deduced peptide is most closely related to eukaryotic type I carbonic anhydrase, based on a comparison with all available carbonic anhydrase sequences. Northern blot hybridization confirmed that the amount of mRNA complementary to the carbonic anhydrase cDNA clone is more than five times higher in ruminal epithelium from mature sheep (12 wk old) than in ruminal epithelium from neonatal lambs (< 12 h old). Messenger RNA complementary to this cDNA clone was found only in the epithelium of the ruminant forestomach compartments (i.e., rumen, reticulum, and omasum), but small amounts of hybridizable mRNA were also found in sheep skin. This carbonic anhydrase cDNA clone will allow the study of transcriptional regulation of the carbonic anhydrase gene during ruminal epithelial development.

*Abstract*:  Lifetime (5 yr) lamb production and wool production from 207 straightbred Targhee (T) and 474 1/4 Finn-1/4 Dorset-1/2 Targhee (FDT) crossbred ewes managed in a range or farm flock system were evaluated for ewe fertility, prolificacy, ewe fleece weight, and total lamb weight weaned per ewe exposed. Data included 2,620 ewe exposures, 2,384 parturitions, 4,638 lambs born, and 3,498 lambs weaned. Ewes were born in 1984 through 1987 and lambed the first time as 2-yr-olds. Expressed as mean annual values, ewe fertility rates were similar (92.2 vs 91.0%, P = .30) for FDT and T ewes. Finn-Dorset-Targhee ewes had higher (P < .001) prolificacy (2.11 vs 1.75), weaned more lambs per ewe exposed (1.41 vs 1.18), produced more total lamb weight weaned per ewe exposed (33.8 vs 29.9 kg), and lambed 2 d earlier than T ewes. Targhee ewes produced more (P < .001) wool (4.5 vs 3.5 kg) than FDT ewes. Range flock ewes had a higher (P < .001) fertility rate (94.5 vs 88.7%), higher number of lambs weaned per ewe exposed (1.38 vs 1.22), and higher total lamb weight weaned per ewe exposed (34.7 vs 29.0 kg) than farm flock ewes. Farm flock ewes had a higher (P < .001) prolificacy (2.00 vs 1.86) and produced more wool (4.2 vs 3.8 kg) than range flock ewes. Targhee ewes had heavier lambs at birth (5.2 vs 4.6 kg; P < .001) and at weaning (25.8 vs 25.4 kg; P < .05). Range flock lambs were heavier (P < .001) at weaning than farm flock lambs (26.2 vs 24.9 kg). Lambs from FDT dams had a higher (P < .01) survival rate than lambs from T dams (75.6 vs 71.4%). Lamb survival from birth to weaning was higher (P < .001) for range flock lambs than for farm flock lambs (76.6 vs 70.4%). Incorporation of Finnsheep and Dorset breeding increased the reproductive performance in both management systems but decreased wool production.

322 **NAL Call No.:  49-J82****Lifetime lamb and wool production of Targhee or Finn-Dorset-Targhee ewes managed as farm or range flock. II. Cumulative lamb and wool production.** Iman, N.

*Abstract*:  Cumulative lifetime (five lamb crops) lamb production and wool production of 681 ewes were evaluated in this study. Lamb production and wool production from each ewe at the end of age 2, 3, 4, 5, and 6 yr were added to the previous year's production and analyzed within age of ewe. If a ewe failed to lamb, died, or was culled, it received a zero for that year and subsequent years. Main effects in the model included ewe breed and management system. Per ewe entering the study, Finn-Dorset-Targhee (FDT) ewes had a higher (P < .01) number of lambs born (7.42 vs 5.70), number of lambs weaned (5.39 vs 4.48), and total lamb weight weaned (131.7 vs 110.5 kg) than did Targhee ewes. Targhee ewes produced more (P < .01) wool (16.1 vs 13.6 kg) than FDT ewes. Range flock ewes had a higher number of lambs born (6.74 vs 6.38; P < .05), number of lambs weaned (5.39 vs 4.48; P < .01), and total lamb weight weaned (135.8 vs 106.5 kg; P < .01) than did farm flock ewes. Farm flock ewes produced more (P < .01) wool (15.2 vs 14.5 kg). A second analysis based on only those ewes retained at the start of each subsequent breeding season showed FDT ewes had a higher (P < .01) number of lambs born (9.96 vs 8.11), number of lambs weaned (7.61 vs 6.57), and total lamb weight weaned (183.8 vs 165.7 kg) after five lamb crops. Targhee ewes produced more (P < .01) wool (22.5 vs 17.6 kg). Farm flock ewes had a higher (P < .10) number of lambs born (9.18 vs 8.89) and produced more (P < .01) wool (21.1 vs 19.0 kg) than range flock ewes. Range flock ewes weaned more (P < .05) lambs (7.27 vs 6.92) and had more (P < .01) total lamb weight weaned (184.3 vs 165.2 kg) than farm flock ewes.

*Abstract*:  For several decades better crop-livestock integration of farming systems in West Asia and North Africa has been promoted as a way to improve crop and livestock output. To achieve this integration, pasture or forage legumes are usually introduced into rotations or grown on fallow land. This paper reports the conceptual framework and methods used in a six-year on-station project which used model farms to investigate the benefits of closer crop-livestock integration and improved husbandry practices. Three farm types were compared. One consisted of a model farm, experimental sheep flock and natural pasture managed using traditional (T) practices. The second had the same enterprise combination but rotations that allowed better integration (1) of the crop and sheep enterprises which were subjected to improved management practices. The third farm type consisted of a sheep flock and natural pasture, with poor (C, control) management practices being applied to the sheep flock. The model farms and experimental flocks were managed by researchers.

*Abstract*:  A six-year project was conducted to show how better crop-livestock integration and improved management increase the outputs of crops and sheep products. Three farm types were compared, consisting of different crop and sheep enterprise mixes, together with natural pastures. The conceptual framework and experimental methods used were reported in a previous paper. This paper reports the crop and sheep enterprise results. Higher yields of grain and straw from wheat and barley crops resulted from improved crop management and better varieties although the contribution of these two factors could not be ascertained. Harvest losses from all crops were substantial and represented a significant economic loss. Input of feeds harvested from the farms or purchased doubled from the poorly managed to the well-managed flock and most of them were offered during late pregnancy and early lactation. Substantial responses in ewe fertility, and offtake of cull ewes, lambs and milk were associated with improvements in feeding level.

*Abstract*:  A six year on-station research project used a model-farm approach to study the benefits of improved crop-livestock integration, achieved through the introduction of leguminous forage species into crop rotations. Previous papers reported the conceptual framework, methods and experimental results. A model farm with integrated crop-sheep enterprises had twice the output of metabolizable energy and a higher stocking rate compared to a model farm with traditional rotations. A linear programming model suggested that integration improved farm profits and stocking rates, but improving the nutritional regime of ewes reduced farm profits. The model-farm approach allows close supervision of animals but otherwise had several weaknesses, in particular the difficulty of mimicking the real farm environment on a research station. If the weaknesses are corrected, the approach could be applied with substantial benefits in national programs that have under-utilized land, animal and staffing resources.

Includes references.*Descriptors:* sheep; free-range-husbandry; lambs; ewes; mortality; age-differences; predation; ursus-arctos; growth-rate; sex-differences; mountain-grasslands

*Abstract*:  Lamb mortality during three summer grazing seasons (1988 to 1990) among 1,399 lambs in three flocks of free-ranging domestic sheep in southeastern Norway was modeled using logistic regression. Ewe mortality during the same three seasons among the 295 ewes in one of the three flocks was also modeled. During the period, mortality among the 1,399 lambs and 295 ewes was 7.2% and 12.5%, respectively. Other work has shown predation by brown bears to be the single most important mortality factor in all three flocks, especially among ewes. Year, herd, sex, age of dam, and spring growth rate (i.e., from birth to release onto summer range) were statistically significant (P less than or equal to .05) in explaining mortality among lambs. Lamb mortality was higher in 1989 and 1990, higher in Herd(A) (the most isolated herd that grazed adjacent to the Swedish border), higher among lambs of yearlings, among male lambs, and among lambs with low spring growth rate. Ewe mortality increased with age (P = .07). Adjustment of age for weight weakened the statistical association between age and mortality, however (P = .16). The negative association between lamb mortality and age of dam and the positive association between ewe mortality and ewe age may both be related to the quality of maternal care provided by ewes of different ages. Subsequently, attempts to compensate for losses, especially those due to predation by bears, lead to a younger herd that may increase the herd's overall vulnerability.

Includes references.*Descriptors:* sheep; artemisia-tridentata; feed-intake; dry-matter; digestibility; hay; voluntary-intake; feces; chemical-composition; urine; nitrogen-content; nitrogen-balance; wyoming

*Abstract*:  A metabolism study evaluated the influence of increasing quantities (0-30% dry matter basis) of mountain big sagebrush (Artemisia tridentata ssp. vaseyana Rydb. Beetle) on dry matter intake and in vivo digestibility of wether diets. Diets consisted of hand-harvested, coarse-ground and frozen current year's growth of mountain big sagebrush leaves and twig tips mixed with chopped native grass hay. Dry matter intake decreased from 93 to 23 g dry matter day-1 kg metabolic weight-1 and in vivo dry matter digestibility from 59 to 0% with increasing levels of sagebrush in the diet. With increasing levels of sagebrush in the diet, water, lignin, and nitrogen contents increased in the diet, but decreased in the dung, while fiber components decreased in both the diet and dung. Total nitrogen intake decreased from 1.58+/-0.041 to 0.406+/-0.070 g day-1 kg metabolic weight-1, and nitrogen retention decreased from 0.80 g day-1 kg metabolic weight-1 with no sagebrush to a slight loss of nitrogen with 30% sagebrush in the diet. Mountain big sagebrush was not readily consumed by wethers when fed together with grass; as low as 10% sagebrush in the diet seems to adversely influence intake and digestibility. Therefore, when other more favorable forages are not available, sheep and other ruminants with similar physiological responses to mountain big sagebrush may not meet their nutrient requirements through increased sagebrush consumption.

*Abstract*:  Nutritional insufficiency and gastrointestinal nematode parasitism are major constraints to small ruminant production in south-east Asia and the Pacific Islands. Research on the effects of low cost supplements which supply nitrogen and essential minerals on the ability of small ruminants to resist infection is summarised. In controlled pen studies in young Merino sheep offered a low quality roughage diet of oaten chaff and essential minerals, supplementation with urea reduced the effects of parasitic infection by increasing weight gain and wool production and reducing faecal egg output and parasite burden. In Fiji, field studies have shown that supplementation with urea-molasses blocks can result in increased live-weights of lambs at weaning, increased reproduction rates in maiden ewes and reduction in faecal egg output in grazing sheep. Additional benefits were derived from the inclusion of anthelmintic in the blocks in similar groups of sheep particularly during periods of greater susceptibility to parasites. Pen studies with young goats have shown that urea supplements alone gave no production benefits, but when accompanied by 100 g/d of cotton seed meal beneficial responses were observed. It is expected that parasite control in the small ruminant production systems of developing countries in south-east Asia and the Pacific Islands will benefit from the introduction of low cost nitrogen supplements along with anthelmintic therapy delivered strategically by molasses blocks.

*Abstract*:  In a digestibility experiment, six adult wethers of the Karagouniko breed were used to determine the nutritive value of dried citrus pulp. The rations consisted of 800 g of hay and 75, 150, 225, 300, 375, and 450 g of citrus pulp. The apparent digestibilities of the DM, OM, CP, ether extract, crude fiber, and N-free extract for dried citrus pulp were 78.6, 87.2, 52.7. 82.0, 93.2, and 83.1%, respectively. Energy content was estimated to be 1.66 Mcal of NEL/kg of DM. In a second experiment, 26 lactating ewes of the Karagouniko breed were used to study the nutrient utilization of dried citrus pulp for milk yield when citrus pulp was used as a replacement for cereal grains. The ewes were divided into two groups immediately postweaning and fed daily 700 g of alfalfa hay, 300 g of wheat straw, and 580 or 550 g of concentrates with or without 30% citrus pulp, respectively. The inclusion of citrus pulp in rations for ewes had no significant effect on milk yield and composition but decreased the C4 to C10 fatty acids. Citrus pulp is a valuable, high energy by-product that can partly replace cereal grains in sheep rations without adverse effect on milk yield or composition.

*Abstract*:  The parturient behavior of 90 Murciano-Granadina goats was analyzed. Hourly frequencies of births showed a unimodal distribution with a maximum number of births between 10:00 and 18:00 h (74.45%). Twenty-four births (26.66%) took place with the goat standing, and sixty-six births (73.33%) took place with the goat recumbent. Fetuses were presented head-first (80.95%), breech (14.97%) and forelegs first (4.08%). Length of labor was 19.49 min for single birth and 30.36 min for twins (first born and second born, 14.52 and 15.84 min, respectively). Time for complete expulsion of placental tissue for goats with single and twin births was 86.58 +/- 4.93 and 106.57 +/- 4.80 min, respectively.

Includes references.*Descriptors:* ewe-milk; volatile-compounds; pecorino-cheese; aroma; diet; gas-chromatography; sesquiterpenes; grasses; feed-grains

*Abstract*:  The neutral volatile compounds of ovine milk from ewes fed on natural pasture, grass meadow, and on mixed grain rations were isolated by distillation under vacuum and then collected in traps that were cooled with liquid nitrogen. The distillate was extracted with dichloromethane, and the extract obtained was analyzed using high resolution gas chromatography and high resolution gas chromatography coupled to mass spectrometry. Seventy compounds were identified and quantitatively determined. The volatile compounds obtained were mainly esters, aldehydes, alcohols, ketones, nitrogen compounds, sulfur compounds, aromatic hydrocarbons, and lactones. The olfactometric indices and olfactory properties of 16 compounds were determined by gas chromatography and olfactometry. All of the substances were present in all three milk types with the exception of two sesquiterpenes, which were not detected in the milk from ewes fed the mixed grain ration. The two sesquiterpenes were absent also in ovine cheese obtained from milk from ewes fed the mixed grain ration, but the two sesquiterpenes were identified in cheese produced from milk of sheep fed on natural pasture. The presence of these constituents in the milk can be significant because of their potential role in determining milk and cheese flavor. Accordingly, cheese obtained during summer may be identified using sesquiterpenes as chemical markers of the milk used to make cheese.

(1996 May) Includes references.*Descriptors:* sheep; feeding-behavior; voluntary-intake; hay; eragrostis-curvula; avena-sativa; forage; nitrogen-retention; sorghum

*Abstract*:  The aim of this study was to determine the effects of experience early in life with cured weeping lovegrass (Eragrostis curvula) (low-quality roughage) or fresh oats (Avena sativa) (high-quality roughage) on voluntary intake and nitrogen retention when sheep ate a low-quality roughage 9 mo after initial exposure. From 1 to 5 mo of age, experienced wethers (EW) grazed cured weeping lovegrass, whereas inexperienced wethers (IW) grazed fresh oats (initial exposure). Then both EW and IW were fed sorghum (Sorghum bicolor) hay for 45 d, fresh weeping lovegrass for 105 d, and finally alfalfa hay for 120 d. Nine months after completion of the initial exposure EW and IW were offered sorghum hay (low quality roughage), and, in addition, both groups were offered sorghum with ad libitum access simultaneously to alfalfa hay at six levels of availability. Experienced wethers ingested 15% more (P < .02) sorghum than IW. When given sorghum simultaneously with alfalfa at different levels of availability, EW ingested more (P < .10) sorghum than IW when only sorghum was freely available. Nitrogen retention was negative in both groups, but it was less negative in EW than in IW per unit of metabolic weight (P < .09) and per wether (P < .04). The results show that early dietary experience can have profound and persistent effects on consumption of foods low in nutritional quality, apparently through changes in critical physiological mechanisms.

*Abstract*:  Analysis of producers' and intermediaries' livestock price expectations was used to describe the market in Quetta, the largest livestock market in the highlands of Balochistan Province, Pakistan, and to identify factors that determine price expectations of small ruminants. A total of 4800 expected prices for sheep and goats were collected from producers and market intermediaries at monthly intervals between January 1991 and December 1992. In addition to the expected price of the animal, liveweight, species, sex, breed, body condition (fatness), calendar day and month were recorded, and whether data were collected on a meat or meatless day. Monthly rainfall data were also collected. Models of goat and sheep price expectations were built to compare the similarity of the behaviour of producers and intermediaries. Results indicated that producers and intermediaries expected high prices from November to January and during religious holidays. They expected premiums and discounts related to animals' attributes. Liveweight and seasonality had the strongest effect on prices. Rainfall in the current and previous month was positively related to seller's expected prices suggesting that livestock are retained to take advantage of favourable grazing conditions. The models of price expectations showed that producers adjusted expected goat prices (P less than or equal to 0.10) for seasonality, liveweight, body condition, age, sex and breed, while they adjusted sheep prices for seasonality and liveweight only. High pay-offs could be expected if extension efforts focused on factors that determine sheep meat quality; however, the retail ceiling price of meat and the lack of grading are a disincentive to work in this direction.  Seasonality of supply and demand is important in determining prices and this study provides baseline information for market scheduling; however, scheduling of sales of transhumant pastoralists may be difficult to achieve. Further investigation is justified to understand the gap in marketing knowledge between producers who sell in the villages and those who sell in Quetta.

*Abstract*:  Eighty Targhee ewes with single or twin lambs were used to investigate the effects of chelated zinc methionine and level of dietary CP on milk and wool production, DMI, and ewe and lamb BW change. Treatments were arranged as a 2 X 2 X 2 factorial. Dietary treatments started 30 d prepartum and continued until 42 d postpartum. Milk production was estimated at 4, 10, 18, and 28 d postpartum. During gestation, DMI by ewes receiving zinc methionine and the 14.9% CP diet was greater (P < .10) than DMI by ewes not supplemented with zinc methionine and ewes fed the 11.3% CP diet. Ewes fed the 14.9% CP diet tended (P < .14) to gain more BW from 30 d prepartum to 4 d postpartum and lose more BW from 4 to 42 d postpartum than ewes fed the 11.3% CP diet. Ewes fed zinc methionine and the 14.9% CP diet produced more (P < .10) milk on d 28 than their counterparts. Ewes rearing twins produced more (P < .05) milk on d 4, 10, and 18 than ewes rearing single lambs. However, milk production on d 28 was not affected by number of lambs reared ( P = .68). Lamb ADG at 28, 42, and 59 d postpartum was greater (P < .05) for both the zinc methionine treatment and the 14.9% CP diet. Zinc methionine (P = .11) and the 14.9% CP diet (P = .02) increased weaning weights by 6 and 9%, respectively. We conclude that both the zinc methionine supplement and the 14.9% CP diet resulted in more persistent milk production. In addition, when ewes and lambs were fed for an average of 42 d during early lactation, a 14.9% CP diet, and to a lesser degree, a chelated zinc methionine supplement, lamb weaning weights were improved.

*Abstract*:  Two experiments were conducted to study the effect of high dietary Cu and duration of feeding time on tissue mineral composition of sheep to establish a standard curve for future bioassay of supplemental Cu sources. In Experiment 1, 24 crossbred wethers were fed a basal diet (9.24 mg/kg Cu) supplemented with 15, 30 or 45 mg/kg added Cu as cupric acetate for 15 or 30 days. An additional four sheep were killed at day 0 to serve as controls. In Experiment 2, 30 crossbred wethers were injected i.v. with 50 mg ammonium tetrathiomolybdate (ATM) twice weekly for 3 weeks to reduce body Cu stores, then fed the basal diet (7.29 mg/kg Cu) or the basal plus 20, 40, 60 or 80 mg/kg added Cu as cupric acetate for 10 or 20 days. Treatment with ATM reduced liver Cu stores by 52%. In Experiment 1, liver and bone Cu concentrations were greater in sheep supplemented with Cu compared with controls, but there was no difference among sheep fed various added Cu concentrations. In Experiment 2, liver Cu concentration increased linearly in sheep fed 10 days and quadratically in sheep fed 20 days, but serum, spleen and kidney Cu concentrations were not affected by treatment. A bioassay for Cu bioavailability based on liver Cu uptake with a 10-day supplementation period appeared feasable.

Includes references.*Descriptors:* sheep; cloning; embryos; embryonic-development; cell-lines; embryo-transfer

*Abstract*:  Nuclear transfer has been used in mammals as both a valuable tool in embryological studies and as a method for the multiplication of 'elite' embryos. Offspring have only been reported when early embryos, or embryo-derived cells during primary culture, were used as nuclear donors. Here we provide the first report, to our knowledge, of live mammalian offspring following nuclear transfer from an established cell line. Lambs were born after cells derived from sheep embryos, which had been cultured for 6 to 13 passages, were induced to quiesce by serum starvation before transfer of their nuclei into enucleated oocytes. Induction of quiescence in the donor cells may modify the donor chromatin structure to help nuclear reprogramming and allow development. This approach will provide the same powerful opportunities for analysis and modification of gene function in livestock species that are available in the mouse through the use of embryonic stem cells.

*Abstract*:  This paper is the first in a series that presents the development and use of a quantitative model of a sheep grazing system. The animal growth model presented here draws from a range of sources reported in the literature, and accounts for interactions between an animal's physiological state and herbage quality on diet selection and levels of feed intake. The model estimates partition of energy between maintenance, pregnancy, lactation, wool growth and fat and protein accretion. The model was tested against a range of published data and was found to be acceptable for its intended use as a research tool to evaluate animal performance and the physical and economic consequences of alternative technologies and management strategies.

*Abstract*:  This paper presents the implementation of a farm management model of sheep grazing systems and demonstrates how the model can be used to gain incremental information about the system being investigated. The structure of the model is presented in detail, including a description of the data structures used to represent paddocks, mobs, pasture and animal production, and a flexible management component which controls the operation of the model. An experiment is presented that explores potential carrying capacities, requirements for pasture conservation, and appropriate levels of winter feeding for dryland and irrigated properties in the Canterbury Plains of New Zealand. The results of this experiment are then used as inputs to a second experiment that evaluates the effects of stocking rate on animal performance, meat and wool production and profitability.

Includes references.*Descriptors:* mouflon; ewes; lambs; animal-behavior; rams; peer-relationships; spatial-distribution; proximity

*Abstract*:  The spatial structure of groups of Mediterranean mouflon was compared during spring/summer in a small population living on a sandy terrace in eastern Germany and within part of a large population inhabiting a low mountain in southern France. A similar comparison was also conducted throughout the year in the French population. The aim of the study was to define proximate mechanisms participating in the spatial structure of the groups. We measured the proximities in the group, distances to nearest neighbours and activity of the individuals according to their sex and age. Lambs and females were closer to each other than to the other individuals on average at both sites and throughout the year (closer in 55-57% of the couples). Lambs tended to be central to the groups and females peripheral (19 groups with central lambs vs. eight groups with peripheral lambs in Niederfinow in spring/summer, P = 0.04). Lambs, yearling males and adult males were closer to peers but some variations were found between sites and periods. The distance to the nearest neighbour was not clearly correlated with the frequency of association. The proportion of individuals behaving like their nearest neighbour was higher when the distance between them was short (Niederfinow, spring/summer: N = 8, p = -0.857; Vialais, autumn/winter N = 8, p = 0.976). This was no longer true when lambs were excluded from the analyses. Nearest neighbours were close when both were engaged in the same activity other than feeding, they kept a medium distance when both were feeding and they were more distant when only one of them was feeding. The differences between the two populations did not affect the spatial behaviour of the individuals in the groups except for a slight tendency of the animals to be closer in the German population. We propose an explanation of the spatial structure of the groups based on the behavioural characteristics of the different sex and age classes and we discuss the concordance of our results with those found in domestic species.

Includes references.*Descriptors:* agave-tequilana; vinasse; distillery-effluent; waste-water; pollutants; sheep; feeds; nutritive-value; digestibility; fattening-performance; waste-utilization; efficacy; fermented-solids

*Abstract*:  Digestibility and sheep feeding trials were conducted to determine the efficacy of using fermented solids (FS) collected by centrifugation from tequila distillery wastewater. In the digestibility trial, 12 growing Pelibuey crossbred male sheep weighing 30 kg on average were randomly assigned to one of the following four dietary treatments (dry basis) in three replicates: (1) basal diet (BD); (2) DB + 15% fermented solids (FS); (3) BD + 30% FS and (4) BD + 45% FS. Apparent digestibility of dry matter, crude protein and organic matter for these diets were determined. Apparent digestibility of dry matter and crude protein for FS were also determined. The feeding trial was conducted with 36 sheep (average initial weight 19 kg). Animals were randomly assigned to one of 12 pens (three sheep per pen). Each pen was randomly assigned to one of the four diets used in the digestibility trial, so that each dietary treatment was fed to three pens of sheep. Average daily gain and feed intake were measured over a 56 day period with subsequent calculations of the feed:gain ratio. It seems that fermented solids can be utilized successfully by sheep which consequently can contribute to feed cost savings and to solve environmental problems of the tequila industry.

500 **NAL Call No.:  TD930.A32****The value of cowpea husk to the goat.** Adeloye, A. A. *Bioresour-technol* v.52(3): p.281-282. (1995) Includes references.*Descriptors:* cowpeas; husks; goats; goat-feeding; fattening; nutritive-value; acceptability; liveweight-gain; feed-conversion; fattening-performance

*Abstract*:  Eight Sokoto red grower goats weighing 10-12 kg, in a randomized complete block design, were used in growth and digestion studies to determine the value of cowpea husk to the goat. The experimental diet was milled cowpea husk, providing an all-concentrate diet. The control diet was a 40:60 concentrate:grass mixture. The concentrate was made up of 3 parts of ground maize to 2 parts of soybean cake. The grass forage was Pennisetum purpureum. Parameters for assessment were dry matter feed intake, live weight changes, feed conversion and nitrogen utilization. The experiment lasted 65 days, comprising 60 days of growth study and 5 days digestion trial. The performances of the goats on cowpea husk were superior (P < 0.05) to the control, with growth rate of 110 g/day, dry matter feed intake of 4.03% BW and feed conversion of 225.2 g gain/kg feed intake. The cowpea husk was well accepted by the goats, as indicated by its dry matter intake and conversion. Nitrogen utilization tests indicated a high nutritive value of the protein from the crop waste. The energy utilization was suggested to be due to the crude fibre content of the diet. These observations indicate the suitability of cowpea husk feed properties and nutrient utilization for the goat. Cowpea husk could serve as an efficient fattening ration and dry-season feed for the ruminants.

501 **NAL Call No.:  49-J82****The value of soybean hulls as a replacement for corn in beef cattle diets formulated with or without added fat.** Ludden, P. A.; Cecava, M. J.; Hendrix, K.

*Abstract*:  One hundred twenty crossbred yearling steers (average weight = 445 +/- 32 kg) were used in an 84-d randomized complete block design experiment to determine the value of soybean hulls (SH) as a replacement for corn in concentrate diets formulated with or without added fat (lard). The steers were blocked by weight and allotted to one of eight treatments in a 4 X 2 factorial arrangement of treatments. The main factors were amount of SH (0, 20, 40, or 60% of diet DM) and amount of added fat (0 or 5% of diet DM). The basal diet without added fat or SH contained cracked corn (80%), a urea-based protein supplement (15%), and ground corn cobs (5%). Replacing corn with SH linearly (P = .03) decreased ADG, increased DMI (linear, P = .003; quadratic, P = .06), and linearly (P < .001) decreased gain efficiency. Fat addition tended (P = .08) to improve efficiency; ADG and DMI were unaffected (P > .05) by fat addition. Similar diets were fed to 16 wethers (average weight = 47 +/- 2.3 kg) in a randomized complete block design experiment to determine digestibility of NDF and dietary concentration of DE. Replacing corn with SH linearly increased DMI (P = .001) and NDF (P < .001) and linearly decreased (P < .001) the digestibility of DM. The digestibility of NDF tended to increase with increased SH. The digestibility of energy linearly (P = .0001) decreased with increased SH. The amount of fat had no effect (P > .05) on DMI or intake of NDF or digestibilities of these nutrients. The addition of fat tended (P = .07) to improve the intake of DE. For the conditions of this study, addition of fat to diets had similar effects on performance regardless of the dietary amount of SH. The feed value of SH was estimated as 74 to 80% of that of corn. The use of SH in concentrate diets should be dictated by the cost of SH relative to cereal grains within the context of reduced gain and efficiency, particularly when SH are fed at high concentrations of diet DM.
