Two levels of CM substitution (25 and 50 percent) for industrial concentrate were studied; 3 treatments (with broiler chicks randomly assigned to blocks) during fattening were compared with a check treatment (100 percent industrial concentrate). Slaughter wt. over 1.5 kg/animal were obtained, wit...
