One experiment was conducted to evaluate the performance and carcass yield of two strains of male broilers fed the diets with different profiles of amino acids from 43 to 56 days of age. Data of performance (weight gain, feed intake and feed conversion), carcass yield (dressing, breast, wing, legs, head, back percentage, abdominal fat) and edible bowels (gizzard, liver and heart) were collected. The experimental design involved eight treatments in a factorial 2×4 (two strains – Hubbard and HI-Yield and […]
