The rumen fermentative characteristics of Nelore steers grazing Brachiaria Brizantha pastures (Teste), or supplemented during the dry season (Seca), dry and wet seasons (Ano) or with free access to a Leucaena bank (Banco), in a randomized block design with four replications, were evaluated. The dry season supplement had 46.9% CP, 70% rumen degradable, and the wet season supplement, 43.9%CP, 60% degradable. Rumen liquor was collected on August, November, February and May. The molar proportions of propionic acid in the supplemented […]
