The objective of this study was to evaluate the performance and carcass traits of young bulls, finished in a feedlot and fed diets with sugarcane (Var. SP 80-1816) and two concentrate levels (40 or 60 % of the DM). Fifteen Nellore bullocks, with approximately 330 kg and 18 months old, and 15 Canchim bullocks (5/8 Charolês ×3/8 Nellore), with approximately 300 kg and 15 months old, were used. The animals were housed in individual pens for a period of 126 […]
