Two experiments were carried out to determine the nutritional requirement of total lysine for Hubbard and Ross broiler chickens of both sexes, from 1 to 21 and from 22 to 40 days of age. The evaluated traits were weight gain, feed intake, feed:gain, carcass yield, breast with bone yield, breast meat yield and fat pad. In each phase, a completely randomized block experimental design in a 2 x 2 x 6 factorial arrangement was used, with two sexes, two trade […]
