2Vitamin-mineral premix (JBS United, Sheridan, IN) included the following per kilogram of complete diet: Vitamin A (retinyl acetate), 11,128 IU; Vitamin D3 (cholecalciferol), 2,204 IU; Vitamin E (dl-α tocopheryl acetate), 66 IU; Vitamin K (menadione nicotinamide bisulfite), 1.42 mg; Thiamine (thiamine mononitrate), 0.24 mg; Riboflavin, 6.58 mg; Pyridoxine (pyridoxine hydrochloride), 0.24 mg; Vitamin B12, 0.03 mg; d-Pantothenic acid (d-calcium pantothenate), 23.5 mg; Niacin (nicotinamide and nicotinic acid), 44 mg; Folic acid, 1.58 mg; Biotin, 0.44 mg; Cu (copper sulfate), 10 mg; Fe (iron sulfate), 125 mg; I (potassium iodate), 1.26 mg; Mn (manganese sulfate), 60 mg; Se (sodium selenite), 0.3 mg; and Zn (zinc oxide), 100 mg.
3Metablizable energy and standardized ileal digestible (SID) amino acid values were calculated using NRC (2012). Analyzed crude protein determined as CP = (N × 6.25).
