摘　　要：相同试验条件下,选1~2岁健康的荷斯坦育成牛47头,随机分为四组（组间体重差异不显著）,用四种不同组合的微生态制剂和复合酶制剂育肥60d。结果表明4组和1组的增重效果最好,平均日增重分别高出2组34.40%、18.80%,4组与3组日增重间差异显著（P〈0.05）,而与2组差异极显著（P〈0.01）;1组与其它三个组日增重间差异均不显著（P〉0.05）。每千克增重耗精、粗料排序为：2组〉3组〉1组〉4组。综合考虑,1组增重效果最好。Under the same test conditions,47 healthy and raising holstein at 1-2 year-old which was randomly divided into 4 groups（the difference of body weight among group was not remarkable）.they ware fattened 60d by 4 kind of different microbioecologics and the compound enzyme preparation..The results showed as follows： The average daily gain of 4 group and 1 group were best,which were higher than that of 2 group by 34.40%、18.80%.The average daily gain of 4 group was higher than that of 3 group（P0.05） and significantly higher than that of 2 group（P0.01） The difference of 1 group and other three groups was indistinguishable（P0.05）.The sequence of each kilogram increasing consumes the concentrated feed and roughage was as follows： 2 group 3 group 1 group 4 group.1 group was the best in conclusion.
