Carcass characteristics of 463 steers, born during 1984 to 1996, from two breeding systems: straightbreds (S) and F1 crossbreds were studied. The S breeding system included the 188 Charolais (C) and 125 Nellore (N) steers and the F1 included 72 1/2 C 1/2 N and 78 1/2 N 1/2 C steers. F1 steers were superior than the purebreds in carcass fat percentage, muscle / bone relation, muscle + fat / bone relation and marbling score, being heterosis levels of 3.33, […]
