      本試驗的目的在于研究經(jīng)產(chǎn)母豬妊娠后期、哺乳期日糧中添加葡萄籽多酚對繁殖性能、血清抗氧化指標、初乳營養(yǎng)組成和免疫球蛋白含量的影響。

       將64頭妊娠80d體況相似的經(jīng)產(chǎn)母豬隨機分為4組，每組16頭。4個處理組分別為：1、基礎(chǔ)對照組；2、基礎(chǔ)日糧+200IU/kg維生素E；3、基礎(chǔ)日糧+200g/t葡萄籽多酚；4、基礎(chǔ)日糧+300g/t葡萄籽多酚。試驗期56d，直至仔豬在21d斷奶。檢測記錄母豬繁殖性能、抗氧化指標、血清孕酮和雌二醇水平、初乳營養(yǎng)組成和免疫球蛋白含量。

       試驗數(shù)據(jù)表明，300g/t葡萄籽多酚組死胎數(shù)顯著下降，產(chǎn)活仔率顯著提高（P＜0.05）。200g/t葡萄籽多酚組和200IU/kg維生素E組仔豬斷奶前存活率顯著提高（P＜0.05）。200g/t和300g/t葡萄籽多酚組母豬血清中超氧化物歧化酶和谷胱甘肽過氧化物酶活性顯著提高（P＜0.05）。200IU/kg維生素E組母豬血清中谷胱甘肽過氧化物酶活性也顯著提高（P＜0.05）。300g/t葡萄籽多酚組母豬血清中孕酮和雌二醇水平顯著高于對照組和200IU/kg維生素E組（P＜0.05）。試驗處理對初乳中非脂固形物、脂肪、蛋白、乳糖含量無顯著影響（P > 0.05）。但是與對照組和維生素E組相比，葡萄籽多酚組母豬初乳中IgM和IgG含量顯著提高（P < 0.05）。

       總之，經(jīng)產(chǎn)母豬妊娠后期、哺乳期日糧中添加葡萄籽多酚提高仔豬分娩存活率和斷奶前存活率，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.（轉(zhuǎn)自：豬營養(yǎng)國際論壇）
