^aExperimental diets were a corn-soybean meal based diet (CON), CON + 8% soybean oil (HF), HF + medium dose of branch chain amino acids (BCAAs, 0.11% leucine, 0.06% isoleucine and 0.22% valine; HF-MB), and HF + high dose of BCAAs (0.22% leucine, 0.12% isoleucine and 0.44% valine; HF-HB). ^bThe premix contained (per kg of complete diet): vitamin A, 12000 IU; vitamin D₃, 2000 IU; vitamin E, 24 IU; vitamin K₃, 2.0 mg; thiamine, 2.0 mg; riboflavin, 6.0 mg; pyridoxine, 4 mg; vitamin B₁₂, 24 μg; niacin, 30 mg; pantothenic acid, 20 mg; folic acid, 3.6 mg; biotin, 0.4 mg; choline chloride, 0.4 mg; iron, 96 mg; copper, 8.0 mg; zinc, 120 mg; manganese, 40 mg; iodine, 0.56 mg; and selenium, 0.4 mg. ^cAll nutrient levels, except digestible energy, were measured
