Nutrient values of ingredients used for diet formulation were derived from NRC (2012) or from the supplier product information for nutrient composition. Phase 1 diets were fed d 0 to 15 post-weaning. The phase 2 diet was fed to all pigs from d 15 to 28 post-weaning. SPC = soy protein concentrate (Soycomil P, ADM Alliance Nutrition, Quincy, IL); SDPP = spray-dried porcine plasma (AP920, APC Inc., Ankeny, IA); APP = activated porcine plasma (betaGRO, NutriQuest, Mason City, IA).
The vitamin-trace mineral premix provided the following per kg of 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.
Diet samples were analyzed by APC Inc., Boone, IA.
