Seventy beef males of three breeding systems (BS), straightbreds Charolais (Ch) and Nellore (Ne), G1 crossbreds: 1/2 Ch + 1/2 Ne (1/2 Ch) and 1/2 Ne + 1/2 Ch (1/2 Ne) and G2 crossbreds: 3/4 Ch + 1/4 Ne (3/4 Ch) and 3/4 Ne + 1/4 Ch (3/4 Ne) were used. The number of animals by genetic group was, respectively, 15, 12, 8, 12, 14 and 9. Thirty-five males were castrated (C) at seven months and 35 were kept intact […]

With the objective to study the carcass and the meat qualitative characteristics of young bulls or castrated males, slaughtered at fourteen months of age, fifteen Hereford males were used, eight castrated at seven months and seven kept entire. From birth to weaning animals were raised on improved native pasture, and after weaning, at seven months, they were confined. Meat measurements were taken from the longissimus muscle, and to determine carcass composition the method of manual dissection of muscle, fat and […]
