摘要

This study was conducted to evaluate the effects of arginine supplementation levels compared with increased feeding during late-gestation on reproductive performance and piglet uniformity in sows. A total of 44 F1 multiparous sows (Yorkshire × Landrace), with an average body weight of 229.5 kg, were allotted to one of four treatment groups in a completely randomized design (CRD). Dietary treatments consisted of an arginine diet with 0.72%, 1.0%, and 1.5% content (2.2 kg/d for 2 parity, 2.4 kg/d for 3+ parity), and increased feeding treatment (IF; 3.0 kg/d arginine 0.72% diet). Sows were fed experimental diets from day 70 to 115 of gestation. The same lactation diet was provided during the lactation period.There was no significant differences neither in body weight and backfat thickness of sows, nor in lactation feed intake, among the dietary treatments. Additional arginine effects also had no significant influences on reproductive performance and growth of the progeny compared with IF treatment. Additional arginine up to 1.5% improved litter weight at 3 weeks, and litter weight gain linearly (linear, P=0.06, P=0.05). Additional arginine intake during late gestation had no significant difference in blood profiles compared with that of IF treatment group. However, 1.5% arginine treatment had more advantages on protein utilization with blood urea nitrogen after farrowing compared with the 1.0% arginine treatment (P=0.05). The significant effect of additional arginine levels compared with the IF treatment group were not observed in the sows’ reproductive performance and the growth of their progeny. The supplementation with arginine 1.5% in the late-gestation diet of sows had an equivalent effect with an increased feeding diet for piglet birth weight and uniformity.
