Abstract The aim of this study was to assess the effects substituting traditional forage fiber sources with cottonseed cake in diet on both quantitative and qualitative characteristics carcass meat Nelore young bulls. Twenty-four steers starting an average weight 377.8 ± 43.5 kg, were individually housed stalls provided individualized feeding over a 112-day confinement period. followed completely randomized design two treatments 12 replications. diets incorporated either whole plant corn...
We investigated the effects of nitrogen (N) fertilisation levels on structural, productive and morphogenetic traits, chlorophyll content, tiller number (TN) macronutrient uptake capacity three Panicum maximum cultivars (BRS Zuri, BRS Quênia Tamani). The experiment was laid out in a completely randomised design with five N doses (0, 50, 100, 200, 400 mg dm−3). concentration increase linearly increasing Zuri. There significant interaction effect between forage mass (FM), yield (FY), TN uptakes...
It was aimed to evaluate the use of cottonseed cake (CSC) as a source physically effective neutral detergent fibre (peNDF) replace corn silage (CS) in diet feedlot-finished cattle. The design used completely randomised, with 2 treatments (30% CSC and 30% CS) 12 replications. There interaction between nutrient material retained Penn State Particle Separator. highest concentrations (P = 0.0001) peNDF vitro digestibility (DpeNDF) were for CSC. higher (p < 0.05) dry matter intake (DMI) (NDF)...
It is estimated that approximately 47% of the world’s ruminant meat and milk produced in tropical subtropical regions, with pasture comprising main food base these animals. Nitrogen fertilisation an essential practice for maintenance productivity, considering a deficiency this nutrient primary factor triggering degradation. In addition to directly influencing photochemical biochemical phases photosynthesis, nitrogen stimulates enzyme activity synthesis enzymes responsible fixing CO2 (Rubisco...
The aim of this study was to predict carcass traits Santa Inês lambs finished in tropical pastures by using biometric measurements. Data originated from two experiments involving 56 (32 experiment I and 24 II). In both experiments, the sheep were that Panicum maximum Brachiaria brizantha, being conducted rainy season II dry season. following measurements recorded before slaughter: body length (BL), withers height (WH), rump (RH), thorax width (TW), (RW), chest (CW), heart girth (HG), thigh...
ABSTRACTThe objective was to investigate the effects of increasing levels extruded urea (EU) in supplementation lambs grazing. Crossbred Texel (n = 45) were used and kept continuous grazing paddocks with Brachiaria spp. The design completely randomised, five EU replacing soybean meal (0; 6; 12; 18 24 g/kg) two sexes (male female). animals slaughtered, qualitative quantitative evaluations carcass, non-carcass components, meat quality chemical composition carried out. There an interaction...
The effects of diets containing oilseeds were measured to evaluate the productive and economic parameters in finishing young, feedlot Nellore bulls. Twenty-four young bulls used, with an initial body weight (BW) 311.46±0.37 kg 24 months age, distributed into individual stalls () a completely randomized design, totaling four treatments six repetitions per treatment. Four (control, based on corn soybean meal, three cottonseed, soybean, sunflower) [...]
This study examined fermentation rates and kinetics of sheep rations based on combinations elephant grass hay, gliricidia (Gliricidia sepium) hay or silage, soybean meal corn using in vitro techniques. Three were prepared, namely: Control (elephant + meal); hay); silage silage). A fixed ratio roughage:concentrate 55:45 was maintained for all rations, which isocaloric designed to support gains 200 g/day. The replaced 57.6% the containing 81.8% hay. Fermentation kinetics, dry matter...
ABSTRACT: This study examined the use of Gompertz, Groot, monomolecular, Richards and two-compartment-logistic mathematical models to investigate kinetics in vitro gas production diets composed combinations Gliricidia hay or silage. In addition, effects silage inclusion on cumulative these were evaluated. Rumen fermentation analyzed by methodology. The model parameters estimated using Gauss Newton method, with exception model, which was used Marquardt’s algorithm. Model fit assessed...
The objective of this study was to evaluate the effect fermentation time on qualitative and chemical characteristics Gliricidia sepium silage grown in sergipe agreste. A completely randomized experimental design with five treatments six replicates used. were different opening periods silos (7, 14, 30, 42 60 days after closing date). PVC minisilars 10 cm diameter 30 length production lactic acid influenced (P = 0.01) time, presenting a quadratic positive behavior. buffer capacity showed...
O objetivo foi discutir o efeito da compactação do solo na nutrição mineral e produtividade de plantas forrageiras, resultados obtidos em diferentes situações, a importância avaliar as características físicas pontuar causas efeitos sistemas produção pastos tropicais. Além disso, descrever práticas capazes garantir sustentabilidade áreas implantadas com cultivados minimizar os pisoteio física solo.
Avaliou-se a composição química e cinética de fermentação ruminal quatro espécies forrageiras submetidas ou não à irrigação. As avaliadas foram Urochloa brizantha cv. MG5 (MG-5), Andropogon gayanus (Andropogon), humidicola (Humidicola) Digitaria umfolozi (Digitaria umfolozi). O experimento foi conduzido na fazenda experimental Campus Rural, São Cristóvão, SE. Observou-se diferença significativa (P
The aim of this study was to verify the precision and accuracy 5 models for leaf area prediction using length width blades Megathyrsus maximus cv. BRS Zuri reparametrize models. Data predictor variables, (L) (W) grass tillers, were collected in May 2018 experimental Embrapa Gado de Corte, Mato Grosso do Sul, Brazil. variables had high correlation values (P<0.001). In analysis adequacy models, first-degree that use blade (Model A), × B) linear multiple regression C) promoted estimated...
Abstract The objective of the present study was to evaluate relationship between body weight (BW) and hip width (HW) in dairy buffaloes ( Bubalus bubalis ). HW measured 215 Murrah with a BW 341 ± 161.6 kg, aged three months five years, raised southeastern Mexico. Linear non-linear regressions were used construct prediction models. goodness fit models evaluated using Akaike information criterion (AIC), Bayesian (BIC), coefficient determination R 2 ), mean squared error (MSE), root MSE (RMSE)....
