The aim of this study was to determine the effects of dietary grape seed polyphenols (GSP) supplementation during the late gestation and lactation period on reproductive performance, antioxidative status in serum, nutrient composition, and Ig content in colostrum of multiparous sows. On day 80 of gestation, a total of 64 sows with similar body condition were allocated to a completely randomized block design with 4 dietary treatments (n = 16 sows per treatment): 1) basal diet (CON, control group); 2) basal diet supplemented with 200 IU/kg vitamin E (200VE, positive control group); 3) basal diet supplemented with 200 mg/kg GSP (200GSP); and 4) basal diet supplemented with 300 mg/kg GSP (300GSP). The trial lasted 56 d until the piglets were weaned on day 21 of lactation. Reproductive performance, parameters of antioxidative status, and levels of progesterone (P4) and estradiol (E2) in serum, nutrient composition, and Ig content in colostrum of sows were determined. The number of dead fetuses was reduced, and farrowing survival was significantly improved in the litters from 300GSP-fed (P < 0.05). Preweaning survivability significantly increased in the litters from sows fed 200GSP and 200VE (P < 0.05). The activity of superoxide dismutase and glutathione peroxidase (GSH-Px) in the serum was significantly increased in sows fed 200GSP and 300GSP (P < 0.05). The activity of GSH-Px in the serum also significantly increased in sows fed 200VE (P < 0.05). Sows fed 300GSP had the greatest levels of P4 and E2 in the serum, which was significantly greater than sows fed 200VE and CON (P < 0.05). No significant differences were found among treatments for the content of solids-not-fat, fat, protein, and lactose in colostrum (P > 0.05). However, sows fed GSP had greater IgM and IgG content in colostrum compared with sows fed 200VE and CON (P < 0.05). In conclusion, dietary GSP supplementation during late gestation and lactation improved the farrowing survival and preweaning survivability, enhanced the antioxidant status and hormone levels in serum, and increased the IgM and IgG content in colostrum of sows.
本研究旨在确定在妊娠后期和哺乳期补充膳食葡萄籽多酚（GSP）对经产母猪繁殖性能、血清抗氧化状态、营养成分和初乳 Ig 含量的影响。在妊娠第 80 天，将 64 头具有相似体况的母猪按完全随机分组设计分为 4 个处理组（每组 16 头母猪）：1）基础日粮（CON，对照组）；2）基础日粮添加 200IU/kg 维生素 E（200VE，阳性对照组）；3）基础日粮添加 200mg/kg GSP（200GSP）；4）基础日粮添加 300mg/kg GSP（300GSP）。试验持续 56 天，直到哺乳期第 21 天断奶。测定母猪的繁殖性能、抗氧化状态参数、血清孕激素（P4）和雌二醇（E2）水平、营养成分和初乳 Ig 含量。结果表明，300GSP 组的死胎数减少，产仔成活率显著提高（P<0.05）。饲喂 200GSP 和 200VE 的仔猪断奶前成活率显著提高（P<0.05）。饲喂 200GSP 和 300GSP 的母猪血清中超氧化物歧化酶和谷胱甘肽过氧化物酶（GSH-Px）活性显著增加（P<0.05）。饲喂 200VE 的母猪血清中 GSH-Px 活性也显著增加（P<0.05）。饲喂 300GSP 的母猪血清中 P4 和 E2 水平最高，显著高于饲喂 200VE 和 CON 的母猪（P<0.05）。各组初乳中非脂固形物、脂肪、蛋白质和乳糖含量无显著差异（P>0.05）。然而，与饲喂 200VE 和 CON 的母猪相比，饲喂 GSP 的母猪初乳中 IgM 和 IgG 含量更高（P<0.05）。综上所述，妊娠后期和哺乳期补充 GSP 可提高母猪产仔成活率和断奶前成活率，增强母猪血清抗氧化状态和激素水平，提高母猪初乳中 IgM 和 IgG 含量。
