Efeito da substituição de farelo de soja por resíduo seco de destilaria de milho com solúveis na dieta de bovinos terminados a pasto

Abstract

The objective of this experiment was to evaluate the effect of substituting soybean meal by dry corn distillery residue with solubles in the diet of cattle finished on pasture. Fifteen Senepol x Nelore F1 animals were used, with an average age of 13 months, where the animals were randomly divided into three treatments, where they received different supplements for each lot, with treatments divided into levels of 0%, 50% and 100 % replacement of soybean meal by DDGS in its composition. The experiment lasted 75 days, where the animals were in intensive finishing on Mombaça grass pasture, with supply of trough and water ad libitum. The experimental design was randomized blocks, where initial live weight (PVI), final live weight (FW), weight gain (GP), carcass weight (PC), carcass yield (RC) and average daily gain were evaluated (GMD). Data were analyzed using the mean comparison test. There were no significant differences for the variables PVI, PVF, GP, CR, PC and ADG. Therefore, it is concluded that the dry residue of corn distillery with solubles in the diet of cattle finished on pasture did not promote changes in performance compared to soybean meal in the diet of cattle finished on pasture.
