摘要: 本实验旨在研究黄芪多糖对泌乳期荷斯坦奶牛抗氧化能力的影响。试验选取年龄、胎次和体重接近的泌乳期荷斯坦奶牛35头,随机分为5组(每组7头),各组每天分别在精料中添加0、5、10、50、100 g黄芪多糖,连续饲喂14 d。分别在第0、14和24 d采血测定血清总抗氧化能力(total antioxidant capacity,T-AOC)、超氧化物歧化酶(superoxide dismutase,SOD)活性、谷胱甘肽过氧化物酶(glutathione peroxidase,GSH-Px)活性及丙二醛(malondialdehyde,MDA)含量。结果显示:在日粮中添加适量的黄芪多糖显著提高(P<0.05)泌乳期奶牛血清总抗氧化能力(T-AOC)、超氧化物歧化酶(SOD)活性和谷胱甘肽过氧化物酶(GSH-Px)活性,同时显著降低(P<0.05)血清中丙二醛(MDA)的含量。结果表明,日粮中添加黄芪多糖有提高泌乳期奶牛抗氧化能力的作用,适宜添加剂量在10 g~50 g/头·d。

Abstract: The aim of this study was to analysis the effect of Astragalus polysaccharides(APS) on antioxidant capacity of lactating Holstein cows.In trial,35 lactational Holstein cows were randomly divided into 5 group(7 per group) with similar age,calving number,and weight.0,5,10,50 and 100 g of APS were added to each group in order with concentrated feed every day and lasting for 14 days.The total antioxidant capacity(T-AOC),activity of superoxide dismutase(SOD) and glutathione peroxidase(GSH-Px),and the content of malondialdehyde(MDA) in serum were determined at 0 day,14th day and 24th day after feeding APS,respectively.The results showed that T-AOC,activity of SOD and GSH-Px were significantly improved (P<0.05),and the content of MDA was significantly decreased (P<0.05) under the influence of the appropriate APS.The results indicated that addition of APS in daily ration can improve the antioxidant capacity of lactational cows and the suitable amount of APS is 10 g to 50 g per day for each cow.

Key words: astragalus polysaccharides, holstein cows, lactational period, antioxidant capacity
