title: Spatial variability of yield response and morphological Marandu grass depending on the chemical and topographical.

description: SUMMARY This work aimed to evaluate the spatial variability of structural and productive responses of Marandu grass depending on the chemical characteristics of the soil and topography. The experiment was conducted in a topossequence, school of Veterinary Medicine and Animal Science, The V variables were evaluated CTC, SB, m, pH at a depth of 0-20 cm, effective depth, number of tillers (m2), production dry matter (kg ha-1), when sward (cm). 72 samples were collected in georeferenced points on sloping ground. The soil was classified as Entisol in the upper portion (top), Udorthent Eutrophic the upper third of the slope (shoulder), Udorthent eutrophic in the middle third of the slope (half-slope) and Quartzips amment Hydromorphic in the lower third (pedimento). All variables presented spatial dependence with variograms of well-defined structure. The pasture presented heterogeneity in the morphology of the canopy due to the spatial distribution of soil fertility, resulting in canopy and producing higher dry matter at the top and reaching the lower production on the shoulder of topossequence. The sward has heterogeneity in morphology depending on the spatial distribution of soil fertility and the effective depth, resulting in the creation of two management areas: 1àtopo and pediment, and 2à shoulder and half hillside.

title: Metabolic profile of lactating goats fed integral mango meal

description: SUMMARY The work was conducted to evaluate the metabolic profile of lactating goats fed diets containing integral mango meal as a replacement for corn. Four levels of replacement (0, 33, 66 and 100%) were evaluated in diets with forage:concentrate ratio of 60:40. Eight crossbred multiparous lactating Saanen goats (48.72 ± 1.99 kg of BW) were introduced in the experiment 48 days postpartum and maintained up to 124 days of lactation. It was used a double Latin Square (4x4) experimental design, with four treatments, four periods and four animals per square. There was no effects (P&gt;0.05) for the integral mango meal level on the intake of DM (1890 g/day), CP (278 g/day) and NDF (959 g/day). However, the intake of NFC and TDN decreased (P&lt;0.05) 27.9 g/day and 0.082 kg/day, respectively, as the dietary integral mango meal increased. The concentrations of urea, creatinine, gamma glutamyl transferase, aspartate aminotransferase, albumin, total protein, glucose, triglycerides, total cholesterol, and magnesium were not altered (P&gt;0.05) by replacement levels, with average values of 54.52 mg/dl, 0.71 mg/dl, 52.59 UI, 77.37 UI, 4.69 g/dl, 9.32 g/dl, 74.44 mg/dl, 40.10 mg/dl, 39.39 mg/dl, and 11.09 mg/dl, respectively. Considering the metabolic profile, mango meal whole can totally replace corn in diets of dairy goats.

title: Prediction of physical and chemical composition carcass of ewe lambs by 9-11th ribs section or 12th rib

description: SUMMARY The objective of to adjust and evaluate models for prediction the physical and chemical body composition of ewe lambs from measurements of the section 9-11 th rib (section 9-11) or the 12th rib. Thirty-six lambs were confined in individual stalls fed with increasing levels of concentrate (0; 20; 40; 60 and 80%) to reach 37.70 ± 10.23 kg to slaughter. At slaughter, the right half carcass of each animal was dissected to determine the proportion of muscle (PCM), fat (PCF), bone (PCB), crude protein (PCCP) and ether extract (PCEE). Section 9-11 and 12th rib were obtained in the left half carcass for a similar purpose. The models to prediction were adjusted as possible predictor variables PCM, PCF, PCB, and PCCP and PCEE in section 9-11 (PM9-11, PF9-11, PB9-11, PCB9-11 and PCEE9-11, respectively) or 12th rib (PM12, PF12, PO12, PCB12 and PEE12, respectively). Positive correlation was observed between PM9-11 and PCM (r = 0.69; P &lt;0.001). The PF9-11 was correlated with PFC (r = 0.93, P &lt;0.001). PO9-11 was positively correlated with PCB (r = 0.92, P &lt;0.001). The PF12 generated accurate model for predicting the PCF (R2 = 0.92, P &lt;0.001). Prediction equation for estimating of PCB from PB9-11 was more precise and accurate (R2 = 0.86, P &lt;0.001) than PB12 (R2 = 0.55). It is possible generate models predicting of body physical and chemical components of ewes lambs from section 9-11 and 12th rib.

title: Management of anthelmintics to the control of gastrointestinal infections in goats

description: SUMMARY This study aimed to evaluate the effectiveness of the active ingredient oxfendazole and the association of this with levamisol, reduction of eggs per gram of feces (EPG) and larvae of helminths in the feces of goats without defined breed (SPRD) created pasture under continuous grazing grass (Panicum maximum), and the action time after application of medicines. The treatments were: no animals wormed (ND); animals wormed with oxfendazole (DO); and animal wormed with oxfendazole association and levamisole (DOL). Between the treated groups, the group where the goats were submitted to association of active ingredients (DOL), was shown to be 16.75% more efficient compared to the group treated with oxfendazole (DO). A peak reductionTrichostrongylus and Haemonchus larvae at 3th and 9th days, respectively, after application of an anthelmintic in relation to worming day. Nevertheless, until the 9th day was not observed efficacy above 95%, can be considered a likely resistance to the principles used. Although it has not reached the expected efficacy, this combination was more effective in reducing larvae of Trichostrongylus genus, when compared to isolated use of the drug. Could be an alternative to the recommendation of anthelmintics association in the control of gastrointestinal infections in goats raised on pasture.

title: Comparison of methodologies used in the analysis of parameters of blood and total protein of Nile tilapia (“Oreochromis niloticus”)

description: SUMMARY Hematology fish contributes to the understanding of the physiology, phylogenetic relationship, feeding conditions and other environmental parameters. This study comparative the effects of anticoagulants, ethylenediaminetetraacetic acid - EDTA and heparin, on blood constituents of Nile tilapia. 25 animals were used with a mean weight of 28.6 ± 13.0g for the collection of the blood sample and determining the number of erythrocytes, hemoglobin concentration, packed cell volume, total protein, total count and differential leukocytes and thrombocytes. Were also compared some of the techniques used for the analysis of these constituents, as diluents and stains. Data were subjected to analysis of variance, and compared using the Wilcoxon test (P&gt;0,05%). The anticoagulants were as effective inhibition of coagulation and the occurrence of hemolysis. Differences were observed in erythrocyte count, in the comparison of anticoagulants such as the comparison of diluents used (saline and Natt-Herrick). Furthermore, differences between techniques for analysis of hemoglobin concentration and between the stains used for preparation of blood extensions (rapid panoptic and Rosenfeld) was found. The results of this study allow us to conclude that both are effective anticoagulants in the preservation of blood characteristics of Nile tilapia. However, the combination of EDTA with Rosenfeld dye showed better results in morphotypes analysis of leukocytes, particularly with regard to cell differentiation.

title: Greenhouse gases, short-chain fatty acids and ruminal pH in vitro of biodiesel byproducts to replace corn silage

description: SUMMARY The aim of the study was evaluate the production potential for methane (CH4) and carbon dioxide (CO2), short-chain fatty acids, ammonia nitrogen (N-NH3) and pH by semi-automated techniquein vitro from biodiesel byproducts cottonseed cake (Gossypium hirsutum), castor bean (Ricinus communis), moringa cake (Moringa oleifera), jatropha cake (Jatropha curcas) and sunflower cake (Helianthus annuus) substituting corn silage in increasing levels, 0, 30, 50 and 70%. The experimental design used was completely randomized in a 5 x 4 factorial arrangement (byproducts and substitution levels). The inoculum for the in vitro incubations was obtained from three Holstein cows with rumen fistulas. In the experiment, the conditions were verified for the differences in potential gas production among the ingredients. The byproduct of cotton was the ingredient with the greatest potential to produce acetate, butyrate, CO2 and CH4. The byproduct of moringa had the lowest potential for the production of acetate, butyrate, CO2 and CH4 from in vitro degraded dry matter and a greater potential for the production of propionate. Among the byproducts studied, moringa was distinguished for promoting mitigation of CH4 and obtaining levels of pH and N-NH3 satisfactory for maximum rumen fermentation; thus, it is recommended the byproduct of moringa to replace corn silage because reduces environmental impact without impairingin vitro rumen fermentation.

title: Culture of the Nile tilapia “Oreochromis niloticus” in biofloc system with different stocking densities

description: SUMARY This work aimed to evaluate the water quality and the growth performance of Nile tilapia (Oreochromis niloticus) cultured in bioflocs system with different stocking densities. The experiment was conducted at the Aquaculture Station of the Federal Rural University of Pernambuco, Brazil, during 128 days. Fish 123.0 ± 0.6 g were stocked in twelve 800 L circular tanks in a completely randomized design with three treatments (D15, D30 and D45, related to densities of 15, 30 and 45 fish.m-3) and four replicates. Among water quality variables, dissolved oxygen had a significant effect (P≤0.05) between the densities, with the lowest concentration (3.97 mg O2.L-1) for the highest tested density (45 fish.m-3). The total ammonia present statistical difference between the D15 and the others; and also, the nitrite, between density 15 and 45 fish.m-3, but both at a directly proportional relationship with the increasing of stocking density, showing higher average concentrations of 2.56 and 3.26 mg.L-1 (NH3+NH4 and NO2,respectively), in 45 density fish.m-3. The growth performance in the 45 fish.m-3 density showed the best results, with yield of 16.6 kg.m-3, with significant difference between treatments (P≤0.05). Survival was higher than 90% at the three tested densities. Bioflocs technology can be employed in intensive culture of Nile tilapia O. niloticus in the growout phase, using stocking densities up to 45 fish.m-3.

title: Yield and nutritional value of shoots and tuberous roots of eight industry cassava genotypes

description: SUMMARY In this study we evaluated the yield and nutritional value for ruminants of shoots and roots of eight industry cassava genotypes (BGMC 1304, BGMC 1299, BGMC 1297, BGMC 1262, BGMC 991, BGMC 923, BGMC 788 and BGMC 436), grown at Embrapa Cerrados experimental field in Planaltina-DF (15 ° 35 '30' south latitude, 47 42 '30' west longitude at 1000 m altitude). The shoots of all genotypes were pruned twelve months after planting. Eighteen months after planting shoots and the tuberous roots of each genotype in each plot were harvested. The experimental design was a randomized block with three replications and means were compared by Scott-Knott. There were significant differences among genotypes for shoots and roots dry matter yield (DMI) as well as in terms of nutritional traits, except for potassium, phosphorus, magnesium and copper in shoots and in vitro dry matter digestibility (IVDMD), potassium, calcium and magnesium in roots. The BGMC 1304 showed higher yield of shoots (8,554kg ha-1) and mean levels of 44.24% and 12.58% for IVDMD and crude protein (CP), respectively. The BGMC 923 stood out for its higher root yield (17,760kg ha-1) with averages of 86.93% IVDMD and 2.27% CP.
