摘要:

为了研究复方中草药对断奶仔猪抗氧化功能的影响。选取20日龄杜长大三元杂交仔猪50头，随机分为５组，每组10头。27~31日龄时分别以基础日粮为对照组、4个实验组分别为转移因子组和在基础日粮中添加0.5%、1.0%、2.0%复方中草药组。在35、45、55、65日龄时每组随机抽选5头仔猪，前腔静脉采血，测定谷胱甘肽过氧化物酶（GSH）、超氧化物岐化酶（SOD）、丙二醛（MDA）。结果表明，与对照组相比，中药组和转移因子组均能提高仔猪SOD、GSH-Px活性(P<0.05或P<0.01)和降低MDA含量(P<0.05或P<0.01)，但日粮中添加1.0%复方中草药组提高断奶仔猪抗氧化功能最佳。

Abstract:

To investigate the effect of compound traditional Chinese herbal on the antioxidant function in weaned piglets,a total of 50 healthy Duroc×Landrace× Yorkshire weaned piglets at 20- day-old were divided randomly into 5 groups with 10 replicate per pen and fed corn and soybean meal-based diets containing 0, Transfer factor(TF),0.5%,1.0% or 2.0% of Chinese medicine on 27 to 31 d,repectively. SOD，GSH and MDA were measured on 35,45,55 and 65 d in 5 piglets from each group .Compared to the control group the SOD and GSH-Px were significantly increased and the MDA were significantly decreased(P<0.05 or P<0.01)in Chinese medicine and transfer factor groups(P<0.05 or P<0.01).These data indicated that the compound Chinese herbal medicine improves the antioxidant function,but the group of 1.0% is better than others.
