The effects of diet type, amino acid (AA), and apparent metabolizable energy (AME) levels in male broiler diets from d 8 to 21 on blood, small intestine, bone, and growth performance were investigated. Eight experimental diets with 2 protein sources [high inclusion of distiller's dried grains with solubles diet (hDDGS) or high inclusion of meat and bone meal diet (hMBM)], 2 AA densities (moderate or high), and 2 AME densities (2,998kcal/kg or 3,100kcal/kg), were fed to the broiler chicks from 8 to 21 days of age (d). High AME diets may lower feed cost by lowering feed intake. Intestinal morphology changes responded to dietary treatments, which may facilitate nutrients digestion and absorption in high MBM diets as well as in high DDGS diets. In addition, high AA or AME diets from 8 to 20 d improved feed conversion during experimental phase and influenced meat yields at 55 d.
