1 CP, crude protein. 2 One kilogram of premix contained the following: 600,000 IU retinol, 400,000 IU rachitasterol, 112.5 mg coagulation vitamin, 110 mg thiamine, 487.5 mg riboflavin, 187.5 mg pyridoxine, 1.375 mg cobalamin, 1.875 g nicotinic acid, 750 mg pantothenic acid, 70 mg folic acid, 4.75 mg biotin, 3 g Fe (ferrous sulfate), 0.5 g Cu (copper sulfate), 5 g Mn (manganese sulfate), 4.5 g Zn (zinc sulfate), 25 mg I (potassium iodide), and 15 mg Se (sodium selenite). 3 Analyzed values except for metabolizable energy. 4 Metabolizable energy was calculated from the ingredient apparent metabolizable energy (AME) values for chickens. 5 α-tocopherol measured via the HPLC method. Mean value of six random samples of each diet.
