      本试验的目的在于研究经产母猪妊娠后期、哺乳期日粮中添加葡萄籽多酚对繁殖性能、血清抗氧化指标、初乳营养组成和免疫球蛋白含量的影响。

       将64头妊娠80d体况相似的经产母猪随机分为4组,每组16头。4个处理组分别为:1、基础对照组;2、基础日粮+200IU/kg维生素E;3、基础日粮+200g/t葡萄籽多酚;4、基础日粮+300g/t葡萄籽多酚。试验期56d,直至仔猪在21d断奶。检测记录母猪繁殖性能、抗氧化指标、血清孕酮和雌二醇水平、初乳营养组成和免疫球蛋白含量。

       试验数据表明,300g/t葡萄籽多酚组死胎数显著下降,产活仔率显著提高(P<0.05)。200g/t葡萄籽多酚组和200IU/kg维生素E组仔猪断奶前存活率显著提高(P<0.05)。200g/t和300g/t葡萄籽多酚组母猪血清中超氧化物歧化酶和谷胱甘肽过氧化物酶活性显著提高(P<0.05)。200IU/kg维生素E组母猪血清中谷胱甘肽过氧化物酶活性也显著提高(P<0.05)。300g/t葡萄籽多酚组母猪血清中孕酮和雌二醇水平显著高于对照组和200IU/kg维生素E组(P<0.05)。试验处理对初乳中非脂固形物、脂肪、蛋白、乳糖含量无显著影响(P > 0.05)。但是与对照组和维生素E组相比,葡萄籽多酚组母猪初乳中IgM和IgG含量显著提高(P < 0.05)。

       总之,经产母猪妊娠后期、哺乳期日粮中添加葡萄籽多酚提高仔猪分娩存活率和断奶前存活率,改善血清抗氧化功能和激素水平,并提高初乳中IgM和IgG含量。

Effects of dietary grape seed polyphenols supplementation during late gestation and lactation on antioxidant status in serum and immunoglobulin content in colostrum of multiparous sows

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.(转自:猪营养国际论坛)
