Abstract

This study was realized to evaluate the dry matter intake, nutrient digestibilities, and animal performance of crossbred steers grazing Brachiaria brizantha cv. Marandu, during the rainy season. Thirty-three crossbred steers with an average weight of 203.5 ± 39.5 kg were distributed in a completely randomized design with three treatments and eleven replications. The results were analyzed using an ANOVA and a Tukey test with a 5% probability of error. The three experimental diets were: MSA – mineral salt ad libitum; MSU - mineral salt + urea ad libitum and PSU - protein supplementation (0.1% of body weight). The dry matter intake of forage and total dry matter intake were similar (P > 0.05) among treatments. The dry matter, organic matter, neutral detergent fiber, crude protein, ether extract, non-fibrous carbohydrates and total carbohydrates digestibilitities coefficients were influenced (P < 0.05) by treatments. The final body weight, average daily gain, and feed efficiency were similar (P > 0.05) among treatments. The supplementation strategies used during the rainy season resulted in a similar performance; therefore, the strategy adopted could be chosen according to the economical and regional conditions of the production.
