摘要: The relationship of growth potential, relative body components, and chemical composition the weight gain to genotype was studied in bulls some French breeds. It evident that animals large beef breeds such as Charolais Maine Anjou have a birth potential superior those smaller or dairy All had carcass, muscle protein yields greater, but an energy content lower than They were less efficient converting intake into net more meat.
