  1. a Treatments were supplemental levels of whey permeate in the diets (Agri-Mark, Inc., Middlebury, Vermont, USA)
  2. b The vitamin premix provided per kilogram of complete diet: 6,614 IU of vitamin A as vitamin A acetate, 992 IU of vitamin D3, 19.8 IU of vitamin E, 2.6 mg of vitamin K as menadione sodium bisulfate, 0.03 mg of vitamin B12, 4.6 mg of riboflavin, 18.5 mg of D-pantothenic acid as calcium panthonate, 26.5 mg of niacin, and 0.07 mg of biotin
  3. c The trace mineral premix provided per kilogram of complete diet: 33 mg of Mn as manganous oxide, 110 mg of Fe as ferrous sulfate, 110 mg of Zn as zinc sulfate, 16.5 mg of Cu as copper sulfate, 0.3 mg of I as ethylene diamine dihydroiodide, and 0.3 mg of Se as sodium selenite
  4. d SID = standardized ileal digestible
  5. e STTD P = standardized total tract digestible phosphorus
