Foi avaliado o efeito da suplementação e do tipo do suplemento sobre a digestibilidade dos nutrientes e o desempenho de bezerros Canchim lactentes mantidos em pastagem de Brachiaria brizantha cv. Marandu durante os meses de fevereiro a maio. Os tratamentos foram: sem e com suplementação em creep-feeding com concentrado proteico, com concentrado energético e com concentrado energético-proteico. Em quadrado latino, foi avaliada a digestibilidade dos nutrientes, utilizando-se quatro bezerros mantidos em baias individuais, recebendo feno da mesma forrageira e com mamadas controladas duas vezes ao dia. O desempenho foi avaliado em delineamento inteiramente casualizado, sendo os 23 bezerros mantidos junto com as matrizes. A suplementação com concentrado... |

The objective of this study was to evaluate the effect of the levels of replacement of ground corn by forage cactus meal in the diet on the muscularity and adiposity of carcass of Santa Inês lambs finished at feedlot. This study was carried out at Estação Experimental de Pendência, belonging to Empresa de Pesquisa Agropecuária da Paraíba S.A. (EMEPA-PB). Forty male Santa Inês lambs in feedlot were used in the experiment. Treatments were randomly assigned to the animals according to a completely randomized design, with four treatments, that consisted of growing substitution levels of ground corn for forage cactus meal: 0, 33, 66 and 100% of substitution and ten replications (lambs). Animals were slaughtered and carcasses cooled for 24 hours for later... |

The objective of this study was to evaluate nutrient intake, performance, estimated methane production and carcass characteristics of steers fed diets containing three different levels of soybean grain: 0, 120 and 230 g/kg on the dry matter (DM). The study was conducted on eighteen castrated Nellore males with an average initial body weight (BW) of 370±12 kg in a completely randomized design, with three treatments and six repetitions. Intake of dry matter (DMI, kg/day) and crude protein tended to decrease linearly, and the intake of ether extract increased linearly in response to the soybean grain levels in the diet. Levels of soybean grain in the diet did not affect DMI (g/kg of BW), final average weight, average daily weight gain, feed efficiency and... |

The effect of the substitution of Tifton hay (0, 33, 66, 100 g/100 g) for pineapple (Ananas comosus L.) stubble hay was evaluated in the characteristics of the carcasses of goats of an unknown breed (UB) in feedlot. Thirty-two bucks with an average initial live weight of 17.5±1.3 kg, at approximately 150 days of age, were housed in individual stalls provided with feeding and drinking troughs. The animals were distributed in a completely randomized design with four treatments and eight replications. There was a quadratic effect on the weights of hot carcass and cold carcass, empty body, and loin eye area. A linear increase was observed for losses by carcass cooling. The weights of commercial cuts and the weights of total muscle, total bone, intramuscular... |
