The objective of this experiment was to evaluate the carcass characteristics of intact or castrated feedlot-finished males slaughtered at 16 (young steers) or 26 months of age (steers). The diet, with 50% roughage and 50% concentrate, contained 11.8% of crude protein and 2.83 Mcal of digestible energy/kg of dry matter. Intact males from both categories showed heavier carcasses. The weight difference between intact and castrated males was more evident for 26-month-old steers (33%) than for 16-month-old (14%) animals. Carcass subcutaneous […]
