Grain corn maize silage and forage corn maize silage evaluation on nelore and canchim cattle performance in feedlot

摘要

An experiment was carried out to evaluate corn [maize] grain and corn [maize] forage variety productivity and the nutritive value of silage based on the performance of cattle in a feedlot. A completely randomized design was used with a 2 X 2 factorial arrangement based on two cattle breeds (Nelore and Canchim) and two corn [maize] types (grain and forage). The corn [maize] was harvested 120 days after sowing, when plants showed more than two-thirds of dry leaves and grain was in the dough stage. The silage was stored in 400-ton silos.
