The carcasses of 800 steers derived from rotational crossbreeding between Charolais and Nellore breeds, slaughtered at two years of age, were evaluated. The evaluated characteristics were the following: conformation, cushion thickness, arm perimeter, Longissimus dorsi area, Longissimus dorsi area divided by 100 kg of cold carcass weight (AOL100). Two models were used for the data analyses: Model 1 included the genetic effects of the breeding system and steer genetic group nested within the breeding system and Model 2 corresponded to […]
