The performance of 192 weaned Nelore steers grazing on Brachiaria brizantha pastures(Teste), or supplemented during the dry season (Seca), all year around (Ano) or with free access to a leucaena bank (Banco), was evaluated in a random block design with four replications. The dry season supplement had 46.9% CP, 70% rumen degradable, and the wet season supplement, 43.9% CP, 60% degradable. During the dry season, the animals of Ano and Seca showed higher gains than Banco and Teste (.534 and […]
