摘　　要：为了研究柯尔克孜羊羔羊补饲营养调控的效果,选择健康无病、胎次和初生体重相近的羔羊40只,随机分为2组(每组20只),对照组按传统方式饲喂,试验组从10日龄开始设羔羊补饲栏进行补饲,测定0~60日龄两组羔羊各日龄段的体尺、体重,并分析两组羔羊各日龄段的平均日增重、相对生长率和体尺性状变化。结果表明,试验组羔羊平均日增重0.31 kg,显著高于对照组(0.22 kg)(P<0.05);试验组羔羊60日龄体重23.06 kg,比对照组提高了30.50%;试验组羔羊的体高、体长和胸围均显著大于对照组(P<0.05)。说明柯尔克孜羔羊早期补饲营养调控可以有效地促进羔羊生长。In order to study the effect of supplementary feeding nutrition regulation on Kirgiz lambs,40 healthy lambs with similar parity and birth weight were randomly divided into two groups(20 lambs in each group).The control group was fed in the traditional way.The experimental group set up a supplementary feeding bar for lambs from the age of 10 days for supplementary feeding.The body size and body weight of 0-60 day old lambs of the two groups were measured,and the average daily gain,relative growth rate and body size traits of the lambs of the two groups were analyzed.The results showed that the average daily gain of lambs in the experimental group was 0.31 kg,significantly higher than that in the control group(0.22 kg)(P<0.05).The body weight of the experimental group at 60 days of age was 23.06 kg,which was 30.50%higher than that of the control group.The body height,body length and chest circumference of the lambs in the experimental group were significantly higher than those in the control group(P<0.05).It shows that early supplementary feeding nutrition regulation of Kirgiz lambs can effectively promote the growth of lambs.
