Structural, electronic, and magnetoresponsive properties of triangular lanthanide clusters and their free‐standing nitrides
Authors: Tsipis Athanassios C. , Stalikas Alexandros V. 
Published: September 2010

AbstractThe molecular and electronic structures, stabilities, bonding features, and magnetoresponsive properties of three‐membered [c‐Ln3]+/0/− (Ln = La, Ce, Pr, Nd, Gd, Lu) and heterocyclic six‐membered [c‐Ln3E3]q (Ln = La, Ce, Pr, Nd, Gd, Lu; E = C, N; q = 0 or 1) rings have been investigated by means of electronic structure calculation methods at the DFT level. The [c‐Ln3]+/0/− clusters are predicted to be bound with respect to dissociation to their constituent atoms, the estimated binding energies ranging from 45.8 to 2056.4 kJ/mol. The [c‐Ln3] rings capture easily a planar three‐coordinated nitrogen atom at the center or above the center of the ring yielding the lanthanide nitride clusters [c‐Ln3(μ3‐N)] adopting a planar geometry, except [c‐La3(μ3‐N)] which exhibits pyramidal geometry. The [c‐Ln3(μ3‐N)] clusters are predicted to be bound, with respect to dissociation to N (4S) atom and [c‐Ln3] clusters in their ground states, the binding energies ranging from 53.9 to 257.9 kcal/mol. The six‐membered [c‐Ln3E3]q rings are predicted to be bound with respect to dissociation to LnEq monomers in their ground states with dissociation energies in the range of 173.8 to 318.0 kcal/mol. Calculation of the NICSzz‐scan curves of the clusters predicted a “hermaphrodic” magnetic response of the [c‐Ln3]+/0/− and heterocyclic six‐membered [c‐Ln3E3]q rings, manifested by the coexistence of successive diatropic (aromatic) and paratropic (antiaromatic) zones. The [c‐La3]+/0/− and [c‐Lu3]− are predicted to be weakly antiaromatic, the [c‐Lu3]0/+, [c‐Lu3C3]+, and [c‐Lu3N3] double (σ+π) aromatic, and the [c‐Gd3C3] and [c‐Gd3N3]+ rings (σ+δ)‐aromatic systems. © 2010 Wiley Periodicals, Inc.

The influence of level of concentrate feeding on the voluntary intake of grass and on live-weight gain by cattle
Authors: Tayler J. C. , Wilkinson J. M. 
Published: September 2010

SUMMARYGrazing and stall-feeding experiments were conducted to examine the effect of giving different amounts of cereal-protein concentrate with grass on the live-weight gain of cattle initially 6 months of age. The effect of level of concentrate on grass intake was also studied in the indoor trial. Experiment 1 took place at pasture, with two stocking rates (high and low) and three levels of supplementation at each stocking rate. The response to supplementation, and rate of live-weight gain by the unsupplemented groups was similar at both stocking rates for a 101-day period from late April to mid-August. The results are discussed in relation to other pasture supplementation experiments, and to those obtained in the indoor experiment. Experiment 2 (stall-feeding) consisted of five levels of concentrate feeding from zero to 100% of the diet. There was little increase in total intake as the proportion of concentrate in the diet increased, and the relationship between grass intake and concentrate intake was rectilinear.Gut fill estimates are presented for each level of concentrate feeding, and results for empty body-weight gain are discussed in relation to live-weight gains. There was a linear increase in weight gain with increasing proportion of concentrate in the diet. Empty body-weight gain is recommended as a less biased assessment of the response of cattle to concentrates given with pasture or forages.
Milk and herbage intake of suckled and artificially reared lambs at pasture as influenced by lactation pattern
Authors: Doney J. M. , Smith A. D. M. , Sim D. A. , Zygoyannis D. 
Published: September 2010

ABSTRACTEast Friesland × Blackface (EFX) ewes with sustained lactation (S) and pure Scottish Blackface (BF) ewes with normal lactation (N) were mated to Suffolk rams. Twenty pairs of twin lambs born to the EFX ewes were used in the experiment. One lamb of each pair was re-allocated as a single lamb to either an EFX or a BF ewe (ER) and the second lamb was artificially reared (AR). At pasture the AR lambs were fed four times daily at levels corresponding to the milk intake of the ER lambs, which was measured weekly. Herbage intake was measured only in wether lambs.The intake of milk and herbage between weeks 3 and 12 was lower in the AR groups than in the corresponding ER groups but the differences were not significant.Total metabolizable energy intake as milk in the ER-S group from weeks 3 to 12 was significantly higher than that in the ER-N group (668 v. 450 MJ). Corresponding intakes in the AR-S and AR-N groups were 613 and 416 MJ. Herbage intake over the same period was 187 and 238 MJ for ER-S and ER-N, and 137 and 219 MJ for AR-S and AR-N. Total intake from milk plus herbage was significantly higher in the S group (855 and 750 MJ, respectively, for ER and AR lambs) than in the N group (688 and 634 MJ).There were negative correlations of herbage intake with milk intake (–0·533) and with live-weight gain (–0·094), and positive relationships between live-weight gain and milk intake (r = +0·832), and between live-weight gain and total intake (r = +0·900). Differences in milk intake resulted in significant differences in live weight at 12 weeks (respectively, 34·6 and 29·7 kg for ER-S and ER-N; 32·3 and 29·1 kg for AR-S and AR-N).It is concluded that lambs reared artificially at pasture may be used to investigate the relationship between milk and herbage intake. It was suggested that if milk does not meet the requirements of voluntary intake or growth potential, herbage intake may be increased to fill the deficit but this does not compensate fully for a lower milk supply.

Authors: Valderrábano J. , Ramón J. P. , Barberán M. 
Published: September 2010

ABSTRACTThe effect on the morphology of the reproductive organs of ewe lambs of exposure to phyto-oestrogens for long periods of time were studied in 10 ewe lambs reared on lucerne compared with 10 controls on Italian ryegrass.Anatomical studies of the reproductive organs showed that the ewe lambs reared on lucerne had significantly bigger reproductive tracts than the controls, the thyroids and the mammary glands were heavier and the latter showed secretory activity. The ovaries of the ewes fed on lucerne were smaller and lighter than those of the controls but no difference in ovarian activity was detected.Microscopic examination showed specific features affecting the uterus, cervix and vagina. The prevalence of neutral mucopolysaccharides in the composition of the cervical mucus found in ewe lambs fed on lucerne indicated a decrease in viscosity of the mucus.
Effects of air temperature, air velocity and feeding level on apparent digestibility, water intake, water loss and growth in calves given a milk substitute diet
Authors: Cockram M. S. , Rowan T. G. 
Published: September 2010

ABSTRACTSix groups of eight 2-day-old calves were placed successively in a controlled environment chamber. Three groups were exposed to air temperatures of 10° and 25°C. A liquid diet of skimmed-milk substitute and 4 I/day of drinking (free) water was offered to each calf. Within each group, calves were allocated to either a low (<0·2 m/s) or a high (>3 m/s) air velocity and to either a low (30 g dry matter (DM) per kg M0·75per day) or a high (40 g DM per kg M0·75per day) feeding level. At 8 days of age the apparent digestibilities of DM at air temperatures of 10° and 25°C were 0·77 (s.e. 0·126) and 0·82 (s.e. 0·126) respectively (P > 0·05). The apparent digestibilities of DM were greater at the low feeding level with low air velocity than for either this feeding level with high air velocity or the high feeding level at both air velocities (P< 0·05) between which there was no significant difference (P > 0·05). At 8 days of age there were significant air temperature × air velocity (P< 001) and air velocity × feeding level interactions in the intake of free water (P< 005). There was a significant air temperature × feeding level interaction for total water intake (P< 0·05). Urinary water loss relative to total water intake was significantly greater at the low air velocity than at the high air velocity (P< 0·05).In a further two groups of eight calves given 30 g DM per kg M 75 per day at 8 days of age, the apparent digestibilities of DM at air temperatures of 10° and 25°C were 0·71 (s.e. 0·020) and 0·90 (s.e. 0·013) respectively (P< 0·01). In the same calves given 40 g DM per kg M0·75per day at 20 days of age, the apparent digestibilities of DM at air temperatures of 10° and 25°C were 0·89 (s.e. 0·009) and 0·93 (s.e. 0·011) respectively (P< 0·05). The free and total water intakes, the ratios of (total water intake-faecal water loss): total water intake and the urinary losses of water were significantly greater at the air temperature of 25°C than at 10°C (P< 0·05). Live-weight gains were lower at 10°C than at 25°C (P< 0·01).The results suggested that air temperature, air velocity and feeding level can affect the health and growth of calves less than 4 weeks of age.
A comparison of soya-bean, sunflower and fish meals as protein supplements for yearling cattle offered grass silage-based diets
Authors: Steen R. W. J. 
Published: September 2010

ABSTRACTTwo experiments were carried out to examine the relative value of soya-bean, sunflower and fish meals as protein supplements for growing beef cattle offered grass silage ad libitum. In each experiment, well preserved grass silage (116 and 119 g crude protein (CP) per kg dry matter (DM) and 69 and 76 g ammonia-N per kg total N in experiments 1 and 2 respectively) was supplemented with (1) barley (107 g CP per kg DM), (2) barley/soya-bean meal (224 g CP per kg DM), (3) barley/sunflower meal (223 g CP per kg DM) and (4) barley/fish meal (218 g CP per kg DM). Each of the supplements was offered at a rate of 1·3 kg per head daily to 32 British Friesian castrated male cattle (mean initial live weight 334 kg) n i each experiment. The treatments were imposed for 118 and 134 days in experiments 1 and 2 respectively and the animals were slaughtered 8 months after the end of the treatment periods. On average over the two experiments for supplements 1 to 4 respectively, silage DM intakes were 6·2, 6·3, 6·3 and 6·2 (s.e. 0·053) kg/day; live-weight gains 0·69, 0·78, 0·71 and 0·80 (s.e. 0·039) kg/day; carcass weights 375, 377, 377 and 374 (s.e. 8·1) kg, carcass fat classification (1 = leanest, 5 = fattest); 3·5, 3·5, 3·4 and 3·6 (s.e. 0·14) and areas of m. longissimus dorsi 19·8, 19·9, 19·7 and 19·3 (s.e. 0·66) mnv/kg carcass weight. It is concluded that when part of a barley supplement given in addition to well preserved grass silage was replaced with soya-bean, sunflower or fish meals, silage intake was not affected. The inclusion of fish meal in the diet increased live-weight gain by HOg/day and the response to soya-bean meal was 0·78 of the response to fish meal per unit of crude protein. Sunflower meal did not affect performance. The treatments did not affect carcass weight or fatness 8 months after the end of the treatment periods.
Rumen degradation of straw. 7. Effects of chemical pre-treatment and addition of propionic acid on degradation characteristics of botanical fractions barley stra treated with a cellulase preparation
Authors: Nakashima Y. , Ørskov E. R. 
Published: September 2010

ABSTRACTFour experiments were carried out to measure the effects of exposure to a cellulase preparation on the degradation characteristics of whole barley straw and its botanical fractions. The effect of chemical pre-treatment (NaOH and H2O2) on treatment with a cellulase preparation and the addition of propionic acid to inhibit loss of dry matter were also studied during the fermentation of ensiled straws. Samples of each preparation were incubated in polyester bags in the rumens of three sheep to estimate degradability. The data were described using the equationp = a + b (1—ec) where p is degradability at time t and a, b and c are constants.The pH of ensiled straw was consistently decreased (P < 0·01) and the solubility increased (P < 0·01) by treatment with a cellulase preparation and by increasing the period of ensiling. The b values were decreased by increasing the length of the ensiling period (F < 0·01). The increase in the solubility of the treated botanical fractions was particularly apparent for the leaf blades, followed by leaf sheath, with the internodes being least affected (P < 0·01). However, treatment with a cellulase preparation had little or no effect in increasing the potential degradability (a + b) of any botanical fraction. The degradability of the whole plant and botanical fractions of straw increased (P < 0·01) with NaOH treatment and was further improved (P < 0·01) by alkaline H2O2 treatment. The increase was greater in internodes than in leaf sheath (P < 0·01). Treatment with a cellulase preparation and chemical pre-treatment had little or no effect on the 48-h dry-matter loss (DML) and the (a + b) values, but it increased (P < 0·01) the a values and solubility.DML from straw treated with a cellulase preparation during fermentation decreased (P < 0·01) from about 60 to less than 10 g/kg with 30 g propionic acid added per kg straw to inhibit bacterial activity. The decreased fermentation loss was reflected in an increase in the 48-h DML and potential (a + b) values of straw treated with a cellulase preparation.
