摘　　要：[目的]研究复合预混料对奶牛抗氧化作用的影响。[方法]把20头奶牛随机分成2组,分别为试验组和对照组,试验组奶牛精料补充料中添加2%预混料,180 d后测定试验组和对照组血清中T-SOD、GSH-Px活性和MDA含量。[结果]与对照组相比,试验组可以提高T-SOD和GSH-Px的活性,降低MDA含量。[结论]添加复合预混料可以提高奶牛的抗氧化能力。[Objective] Effect of anti-oxidative action with the additional premix compound on cow was studied. [Method] 20 cows were divided into the control group and the treated group. The treated cow was appended the 2% additional premix compound. After 180 days, the activities of superoxide dismutase （SOD） , glutathione peroxidase （GSH-Px） and the MDA contents in blood serum were tested,[ Results] The results showed that SOD and GSH-Px activities in the treated group were obviously higher than that in the control group （ P〈0.05） and MDA contents obviously lower （ P 〈0.05）. [Conclusion] Appended 2% additional premix compound could increase the cow＇s ability to anti-oxidative action.
