复方中草药制剂对断奶仔猪抗氧化功能的影响

Effects of Compound Chinese Herbal on Antioxidant Function of Early Weaned Piglets

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。

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.
