摘　　要：为研究补饲不同剂量复合益生菌对泌乳期奶水牛乳成分及产奶量的影响,选取健康状态良好的奶水牛9头,随机分为3组。对照组和试验组所有奶水牛饲喂相同精料及粗饲料,在此基础上对照组、试验I组、试验Ⅱ组分别补喂0、100和200 g复合益生菌,试验期间称量及记录参试牛每天的泌乳量,并且在试验的第0、7、21和35天采集鲜奶测定乳成分。试验结果表明,在日常泌乳水牛饲料中补饲复合益生菌能在一定程度上提高泌乳水牛的产奶量、乳糖和非脂乳固形物含量。补饲复合益生菌能一定程度提高泌乳水牛的生产性能,改善乳品质,添加量以200 g/d效果更佳。In order to study the effect of different doses of compound probiotics on milk composition and milk yield of milk buffalo in lactation period,9 healthy milk buffaloes were randomly divided into 3 groups.All milk buffaloes in the control group and the test group were fed with the same concentrate and roughage.On this basis,the control group,the test group I and the test group II were fed with 0,100 and 200 g of composite probiotics respectively.During the experiment,the daily milk production of buffalo was measured and recorded,and fresh milk was collected on the 0,7,21 and 35 days of the experiment to determine the milk composition.The results showed that the milk yield,lactose and non-fat milk solids content of buffalo could be increased to a certain extent by feeding compound probiotics in the feed of buffalo.Feeding compound probiotics can improve production performance and milk quality of lactating buffalo to a certain extent,and the effect of 200 g/d is better.
