¹Provided the following quantities of vitamins per kilogram of complete diet: vitamin A as retinyl acetate, 11,136 IU; vitamin D3 as cholecalciferol, 2,208 IU; vitamin E as DL-alpha tocopheryl acetate, 66 IU; vitamin K as menadione dimethylprimidinol bisulfite, 1.42 mg; thiamin as thiamine mononitrate, 0.24 mg; riboflavin, 6.59 mg; pyridoxine as pyridoxine hydrochloride, 0.24 mg; vitamin B12, 0.03 mg; D-pantothenic acid as D-calcium pantothenate, 23.5 mg; niacin, 44.1 mg; folic acid, 1.59 mg; biotin, 0.44 mg; Cu, 20 mg as copper sulfate and copper chloride; Fe, 126 mg as ferrous sulfate; I, 1.26 mg as ethylenediamine dihydriodide; Mn, 60.2 mg as manganese sulfate; Se, 0.3 mg as sodium selenite and selenium yeast; and Zn, 125.1 mg as zinc sulfate.

²Values for ME and NE were calculated based on ME and DE in each energy contributing ingredient. Values for ME and NE in corn, soybean hulls, and soybean oil were based on NRC (2012), and values for ME and NE in soybean meal, high-protein canola meal, and conventional canola meal were from Berrocoso al. (2015).

³Standardized total tract digestible (STTD) P. Values were calculated based on standardized total tract digestibility of P in corn, soybean hulls, and dicalcium phosphate published by NRC (2012), and values for standardized total tract digestibility of P in soybean meal, high-protein canola meal, and conventional canola meal were from She et al. (2017).

⁴Amino acids are indicated as standardized ileal digestible AA. Values were calculated based on values for standardized ileal digestibility of AA in corn, soybean hulls, and l-Lys HCL published by NRC (2012), and standardized ileal digestibility values for AA in soybean meal, high-protein canola meal, and conventional canola meal were from Berrocoso et al. (2015).
