摘　　要：为进一步研究羔羊早期断奶技术在天祝牧区肉羊生产的推广应用效果,在天祝牧区开展了天华肉羊羔羊早期断奶育肥试验。选择出生日期、来源地均一致的天华羔羊80只,各试验对象出生重及20日龄体重差异不显著(P>0.05),随机分为试验S1、S2和S3组和对照组D1组,试验组分别于20日龄、35日龄和50日龄集中断奶后育肥,对照组正常补饲。结果显示,试验组育肥期平均日增重分别为217.5、198.1和191.1g,对照组120d的平均日增重为130g,试验组的平均日增重高于对照组,差异显著(P<0.05)。羔羊整个饲养期增重统计显示,试验组的增重和平均日增重分别为32.4kg、231.4g,33.0kg、235.7g和30.4kg、217.1g,各组间差异不显著(P>0.05),而对照组的增重和平均日增重为21.6kg和154.3g,低于试验组,增重量与试验组差异显著(P<0.05)。试验表明,在天祝牧区肉羊生产中推广羔羊早期断奶育肥技术可行且能获得较好的日增重生产效益。In order to further study the promotion and application effect of early weaning technology of lambs in the production of meat sheep in Tianzhu pastoral area,the project team conducted an experiment on early weaning and fattening of Tianhua meat sheep lambs in Tianzhu pastoral area.Eighty Tianhua lambs with the same birth date and origin were selected for the experiment.There was no significant difference in birth weight and body weight among the subjects at 20 day old(P>0.05).They were randomly divided into experimental groups S1,S2,S3,and control group D1.The experimental group was weaned and fattened at 20 day old,35 day old,and 50 day old,respectively,while the control group was fed normally.The results showed that the average daily weight gain of the experimental group during the fattening period was 217.5,198.1 and 191.1 g,respectively.The average daily weight gain of the control group was 130 g at 120 d.The average daily weight gain of the experimental group was higher than that of the control group,and the difference was significant(P<0.05).The weight gain statistics during the entire feeding period of lambs showed that the weight gain and average daily weight gain of the experimental group were 32.4 kg,231.4 g,33.0 kg,235.7 g,and 30.4 kg,217.1 g,respectively.There was no significant difference between the groups(P>0.05),while the control group had 21.6 kg and 154.3 g,which were lower than the experimental group.The difference in weight gain between the experimental group and the experimental group was significant(P<0.05).The experiment shows that promoting early weaning and fattening technology for lambs in the production of meat sheep in Tianzhu pastoral area is feasible and can achieve good daily weight gain production benefits.
