摘　　要：为探究在泌乳奶牛日粮中添加大蒜素对奶牛生产性能、乳成分、瘤胃发酵参数和血清生化指标的影响,本研究选择生理状态相近的中国荷斯坦泌乳奶牛32头,随机分为4组,每天分别补充大蒜素0 g、50 g、100 g和150 g,测定生产性能、乳成分、瘤胃发酵参数和血清生化指标。结果表明,添加大蒜素提高了奶牛采食量(P<0.05),150 g/d组在正饲期60 d时产奶量提高(P<0.05),100 g/d组在正饲期30 d时乳脂率显著增加(P<0.05);添加大蒜素降低了体细胞数和碱性磷酸酶含量(P<0.05),提高了总挥发性脂肪酸含量(P<0.05)和免疫球蛋白A、免疫球蛋白G含量(P<0.05)。100 g/d组血清中总蛋白和球蛋白含量显著升高(P<0.05)。综上,大蒜素改善了奶牛生产性能、乳品质,提高了免疫机能。In order to explore the effects of allicin on the production performance,milk composition,rumen fermentation parameters and serum biochemical indices of lactating dairy cows,32 Chinese Holstein lactating dairy cows with similar physiological status were randomly divided into four groups.Allicin 0 g,50 g,100 g and 150 g were supplemented every day to determine the production performance,milk composition,rumen fermentation parameters and serum biochemical indices.The results showed that the addition of allicin increased the feed intake of dairy cows(P<0.05),the milk yield of 150 g/d group increased during the 60 days formal feeding period(P<0.05),and the milk fat rate of 100 g/d group increased significantly during the 30 days formal feeding period(P<0.05).Allicin decreased the number of somatic cells and the content of alkaline phosphatase(P<0.05),increased the content of total volatile fatty acid(P<0.05)and the contents of immunoglobulin A and immunoglobulin G(P<0.05).The contents of total protein and globulin in serum increased significantly in 100 g/d group(P<0.05).In conclusion,allicin can improve the production performance,milk quality and immune function of dairy cows.
