1Pigs were fed for 21 d on each experiment, 7.1 to 16.6 kg BW for experiment 1 and 9.2 to 12.8 kg BW for experiment 2.
2Dietary treatments consisted of 10% refined soybean oil that was either fresh oil, heated for12 d at 45 °C, heated for 72 h at 90 °C, or heated for 6 h at 180 °C. All heated soybean oil groups had a constant compressed air flow rate at 15 L/min.
3Provided the following per kilogram of diet: vitamin A, 7,044 IU; vitamin D3, 805 IU; vitamin E, 57.5 IU; vitamin K, 3.45 mg; vitamin B12, 0.06 mg; riboflavin, 12.65 mg; niacin, 64.4 mg; and pantothenic acid, 31.05 mg.
4Provided the following per kilogram of diet: Cu (as CuSO4), 15.4 mg; Fe (as FeSO4), 154 mg; I (as Ca(IO3)2), 0.28 mg; Mn (as MnSO4), 36.4 mg; Zn (as ZnSO4), 154 mg; and Se (Na2SeO3), 0.28 mg.
