The non-carcass components of castrated and non-castrated cattle (sex condition) finished in feedlot and slaughtered at 16 (super young) or 26 (young) months of age (animal category) were evaluated. The diet was formulated to contain 11.8% of CP and 2.83 Mcal/kg DM of DE with 50:50 forage to concentrate ratio (%MS). Super young animals showed higher of empty body dressing percentage (92.39 versus 89.76%), as a result of their lower gastrointestinal content (35.23 versus 53.46 kg) as compared to the […]
