The objective of this study was to evaluate the performance, qualitative, morphometric and quantitative carcass traits of Santa Inês lambs of different frame sizes finished in a feedlot. Twenty 120-day-old intact lambs with a 25.0±3.1 kg average body weight at the beginning of the experiment were used. Lambs received a diet containing 17% crude protein and 2.70 Mcal/kg dry matter. Frame size influenced performance and tissue composition in the carcasses of the lambs. Lambs with large frame sizes showed better […]

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 […]
