¹ Experimental diets were fed from day 90 of gestation and farrowing and provided 63 or 200% of the estimated standardized ileal digestible sulfur AA requirements (NRC, 2012). Lactation diet was fed during a 23 ± 5-day period. Dietary treatments were as follows: 0.29% and 0.92% standardized ileal digestible sulfur AAs, which correspond to 63 or 200% of the estimated SID SAAs requirement for primiparous sows in late gestation (requirements from d 90 to d 114 of gestation, 145 kg of body weight at breeding, expected litter size of 15, and piglet birth weight of 1.35 kg). ² Provided per kg of premix: vitamin A, 22,046,000 IU; vitamin D3, 4,188,740 IU; vitamin E, 189,992 IU; vitamin K, 8818 mg as menadione; pantothenic acid, 66,138 mg; riboflavin, 198,414 mg; folic acid, 8836 mg; niacin, 110,472 mg; thiamin, 6613 mg; pyridoxine, 30,313 mg; vitamin B₁₂, 88,184 µg; biotin, 795 mg; Cu, 8088 ppm; Fe, 80,882 ppm; Mn, 21,617 ppm; Zn, 80,882 ppm, as Zinc 80,882 ppm; Se, 147.05 ppm; I, 176.5 ppm. ³ Standardized ileal digestible values are provided in parentheses.
