| 摘 要： | 试验旨在研究在含葵花籽油奶牛日粮中添加酵母硒对奶牛抗氧化性能及牛奶脂肪酸组成的影响。试验选取32头体况、奶产量、泌乳天数相近的奶牛,随机分成4组。对照组A在基础日粮中添加350g葵花籽油,处理组B、C、D在A组日粮基础上分别添加酵母硒8、15、22g。结果表明:酵母硒的添加极显著提高了血清硒(P<0.01);C、D组乳硒较A、B组均有极显著提高(P<0.01);当酵母硒水平为15g时,血清超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)活力达到最大(P<0.05)。酵母硒的添加提高了CLA的含量,当添加量时,15、22g酵母硒可极显著提高乳中CLA的含量(P<0.01)。
