| Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at an average weight of 26.24 kg. No significant differences were observed on morphometric measurements, hot (11.67 kg) and cold (11.39 kg) carcass weight, hot (44.46%) and cold (43.37%) carcass yields, biological yield and on cooling losses. There was also no significant effect of silages of different genotypes of sorghum on the weights and yields of... |

| Este experimento visou estudar os efeitos in vitro dos ionóforos sobre a fermentação ruminal de aminoácidos. Utilizou-se líquido de rúmen de um novilho alimentado com dieta à base de capim-elefante, acrescentando solução de tripticase, em três tratamentos (controle-C, monensina-M e lasalocida-L). Foram feitas transferências diárias de inóculos para novos tubos e, no 11º dia, cada tratamento deu origem a três novos (C, M, L), totalizando nove combinações (2ª fase). Do 1º ao 10º dia de incubação, os ionóforos evitaram o aumento expressivo na produção de amônia comparado ao controle. Do 11º ao 12º dia, os ionóforos foram mais eficientes em decrescer a produção de amônia quando os mesmos estavam ausentes na 1ª fase; e a lasalocida foi ainda capaz de diminuir a... |

| ABSTRACT The objective of this study was to evaluate the effect of substituting soybean meal for urea in diets based on deferred buffelgrass on the performance of feedlot sheep. Thirty mixed-breed sheep with an average initial body weight of 17±1.5 kg were distributed in a completely randomized design in which the experimental treatments consisted of five diets with six replicates. Diets were composed of deferred buffelgrass plus concentrates and calculated to be isoproteic. Treatments were represented by the substitution of soybean meal for the urea levels (0, 25, 50, 75, and 100%). Nutrient intake did not differ among animals fed diets with urea levels. Hot and cold carcass weights, hot and cold carcass dressing percentages, initial and final pH, and... |
