1. PADRÕES COMPORTAMENTAIS DE BOVINOS CONFINADOS COM GRÃOS DE MILHO, AVEIA BRANCA OU ARROZ COM CASCA
Resumo O estudo avaliou o comportamento ingestivo de bovinos terminados em confinamento com dieta de alto grão. Foram utilizados 45 animais do cruzamento das raças Charolês e Nelore, com peso e idade média inicial de 310 kg e 20 meses para os novilhos e 350 kg e 32 meses para as novilhas. Os animais foram distribuídos ao acaso nos tratamentos e bloquead

3. Animal performance and nutrient digestibility of feedlot steers fed a diet supplemented with a mixture of direct-fed microbials and digestive enzymes
ABSTRACT The objective of this study was to evaluate the effect of a mixture of direct-fed microbials (DFM), yeast, and digestive enzymes on animal performance in feedlot cattle, as well as digestibility when finishing feedlot cattle. Thirty crossbreed (Charolais × Beefmaster) steers averaging 15 months old and 321.83±3.73 kg of initial body weight were us

4. Random regression models with B-splines to estimate genetic parameters for body weight of young bulls in performance tests
ABSTRACT The objective of this study was to estimate genetic parameters for body weight of beef cattle in performance tests. Different random regression models with quadratic B-splines and heterogeneous residual variance were fitted to estimate covariance functions for body weights of Nellore and crossbred Charolais × Nellore bulls. The criteria −2 residu

5. Partum and postpartum characteristics on the postpartum rebreeding in beef cattle
ABSTRACT The objective was to evaluate the influence of calving and postpartum characteristics, measured in different genetic predominance, on the postpartum rebreeding. Were evaluated 437 partum from cows that received feeding management consisting of a forage base of the native field and the mating season consisted of 90 days. The measurements were used fr

6. Milk composition and its relationship with weaning weight in Charolais catte
To determine the effects of a number of non-genetic factors on milk components and estimate their indirect relationships with weaning weight (WW205), the percentages of protein, fat, lactose and solids non-fat in Charolais cows from Mexico were estimated. Lactation period (LP) and calving season (CS) had significant effects on protein and fat, whereas lactos

7. Sources of carbohydrates in the ingestive behavior of feedlot steers
In this article we research the influence of different sources of carbohydrates (corn, soybean hulls or wheat bran) upon the digestive behavior of 24 confined castrated steers with an initial average age and weight of 20 months and 330 kg born from the cross between Charolais and Nellore. The diet was composed of 40% sorghum silage and 60% concentrate. The t

8. Risk assessment of finishing beef cattle in feedlot: slaughter weights and correlation amongst input variables
The objective of this study was to evaluate the risk associated with finishing crossbred Charolais × Nellore steers in feedlot at different slaughter weights (425, 467 or 510 kg), considering or disregarding the correlation amongst random input variables. Data were collected from 2004 to 2010 and used in the simulation of the financial indicator Net Present

9. Effects of Lactobacillus buchneri on the nutritive value of sugarcane silage for finishing beef bulls
Lactobacillus buchneri 40788 and the fibrolytic enzymes β-glucanase and xylanase were applied to chopped sugarcane to study their effects on the nutritive value of silage. Sugarcane was mechanically harvested after 14 mo of growth and treated without (control) or with L. buchneri at a theoretical application rate of 5 × 10(4) cfu/g, 1 × 10(5) cfu/g, or 1

10. Performance of finishing steers fed different sources of carbohydrates
The objective of this study was to evaluate the effect of carbohydrate sources (corn, soybean hulls or wheat bran) in the diet on performance of feedlot steers in the finishing phase. Twenty-four Charolais × Nellore crossbred steers, aged 22 months and initial weight of 335.0±10.9 kg were used in the experiment. Diets contained 40% sorghum silage and 60% c

11. FONTES DE CARBOIDRATO NO COMPORTAMENTO INGESTIVO DE NOVILHOS CONFINADOS / CARBOHYDRATES SOURCES ON INGESTIVE BEHAVIOR OF STEERS
Objetivou-se, com este estudo, avaliar a influência de diferentes fontes de carboidratos (milho, casca de soja ou farelo de trigo) sobre o comportamento ingestivo de 24 novilhos castrados com idade e peso médio inicial de 20 meses e 330 kg das predominâncias Charolês ou Nelore. Os tempos despendidos com alimentação (214min./dia) e ruminação total (45

12. SILAGEM DE PAPUÃ OU DE SORGO NA TERMINAÇÃO DE BOVINOS: TECIDOS CORPORAIS E CARACTERÍSTICAS DA CARCAÇA E DA CARNE / ALEXANDER GRASS SILAGE OR SORGHUM IN FINISHING CATTLE: BODY TISSUES AND CARCASS AND MEAT CHARACTERISTICS
O objetivo do presente estudo foi avaliar o efeito do uso da silagem de papuã (Urochloa plantaginea) sobre os tecidos corporais que não perfazem a carcaça, bem como, os aspectos quantitativos e qualitativos da carcaça e da carne de novilhos terminados em confinamento. Utilizaram-se 12 bovinos machos castrados, puros e mestiços Charolês x Nelore, com id
