摘　　要：试验选取体重相近的荷斯坦奶牛犊牛24头,分为试验组和对照组2组,每组12头。试验组犊牛出生5 d内饲喂初乳,之后饲喂代乳粉至42日龄断奶;对照组一直饲喂牛奶至42日龄。结果表明,试验组平均日增重836 g,对照组平均日增重679 g,试验组比对照组日增重提高23.12%;试验期间,试验组胸围、体高、体长分别比对照组提高2.90、1.01、1.56 cm,差异不显著;试验组与对照组的管围无明显差异。说明代乳粉代替牛乳可以达到良好的生产效果。24 Hostein dairy calves with the similar body weight were divided into two groups （12 calls in each group）： test group and control group. The calves in test group were fed with beastings within five days after the birth, and then they were fed with milk replacer till the 42^nd day. The calves in control group were fed with milk before the 42^nd day. The results indicted that the average daily weight gain in test group was 836 g and that in control group was 679 g. The daily weight gain in test group was increased by 23.12% than that in control group.The increased values of chest girth, body height and body length of calves in test group were higher 2.90, 1.01 and 1.56 cm respectively than that in control group, without significant difference. The test group and the control group had no significant difference between the cannon circumference.It was indicated that milk replacer had good production effect, so it could take place of milk.
