| Este trabalho foi realizado com o objetivo de avaliar a influência do grupo racial e da condição sexual nas características da carcaça de caprinos jovens criados em confinamento. Foram utilizados 91 animais, 52 machos e 39 fêmeas, pertencentes a cinco grupos raciais: Alpino, ½Boer + ½Alpino, ½Anglo Nubiano + ½Alpino, ¾Boer + ¼Alpino, e ½Anglo Nubiano + ¼Boer + ¼Alpino. Foi tomado o peso ao jejum, no dia do abate, após 24 horas de jejum de sólidos. Foram tomadas medidas biométricas e de carcaça, objetiva e subjetivamente. O grupo racial influenciou a altura de cernelha, o comprimento interno e externo da carcaça e o comprimento de perna, que foram maiores nos animais Alpinos, bem como a largura do peito, o escore corporal, os índices de compacidade da... |

| The objective of this work was to analyze the interrelations among weights and carcass measures of the longissimus lumborum muscle thickness and area, and of sternum tissue thickness, measured directly on carcass and by ultrasound scan. Measures were taken on live animals and after slaughter to develop models of multiple linear regression, to estimate the composition of shoulder blade, from selected variables in 89 kids of both genders and five breed groups, raised in feedlot system. The variables considered relevant and not redundant on the information they carry, for the common factor analysis, were used in the carcass composition estimate development models. The presuppositions of linear regression models relative to residues were evaluated, the... |

| Objetivou-se avaliar o efeito da suplementação com cromo complexado à molécula orgânica do suplemento no desempenho produtivo, nas características de carcaça e na qualidade da carne de bovinos terminados em regime de pastagem. Foram utilizados 18 bovinos Nelore e 18 F1 Brangus × Nelore castrados, com 16 meses de idade, mantidos com suplementação mineral protéica, com ou sem cromo complexado à molécula orgânica e abatidos aos 22 meses de idade. O ganho médio diário de peso vivo (GMD) não diferiu entre grupos genéticos, entretanto animais mantidos com suplemento contendo cromo apresentaram maior GMD (494 g) em comparação aos demais (420 g). A adição de cromo orgânico no suplemento não promoveu alterações na área de olho-de-lombo (63,42 cm²) e na espessura de... |

| The objective of this experiment was to evaluate levels of replacement (0, 33, 67 and 100%) of corn silage with fresh sugarcane in dairy-goat diets on the ingestive behavior of these animals. Eight lactating Alpine goats (after lactation peak) with a live weight of 51.95±3.29 kg were distributed into two 4 × 4 Latin squares according to their milk production. Animals were placed in individual pens where they received diets ad libitum, twice a day, with a roughage:concentrate ratio of 40:60, during 72 days of experiment. The evaluated variables were time spent feeding (TSF), ruminating (TSR), idle (TSI) and chewing (TSC), dry matter intake (DMI), neutral detergent fiber intake (NDFI), feeding efficiency of dry matter (FEDM) and neutral detergent fiber... |

| ABSTRACT Pasture-based production systems and alternative foods can be used to reduce goat milk production costs by around 20%.The objective of this study was to examine the effect of substituting the corn and soybean meal of the concentrate with cassava chips and alfalfa, respectively, on the feed intake, fermentation, and rumen degradability parameters of adult, dry, empty, rumen-cannulated Saanen goats reared in a feedlot. The experiment was conducted as a Latin square design in which the following diets were tested: ground corn and soybean meal; cassava chips and soybean meal; ground corn and alfalfa; and cassava chips and alfalfa. The following variables were evaluated: feed intake, rumen parameters, short-chain fatty acid (SCFA) production, and feed... |

| ABSTRACT This study was conducted to investigate the effect of selective feeding habits on the quality of the ingested diet and the effect of feed restriction on the selectivity and behavior of goats in feedlots. Differences were found only in the amount of feed given to the animals, with a difference in the amount of feed rejected as a function of the nutritional level. Higher levels of orts were measured for those animals that received the ad libitum diet. For the composition of orts, differences were measured only in the ether extract fraction. Animals fed the ad libitum diet increased their intake of ether extract and energy, crude fiber, neutral detergent fiber, and acid detergent fiber. Thus, they had a preference for consuming the fibrous and... |
