摘　　要：本试验主要研究自由饮用酸化奶对羔羊生长性能的影响。基础母羊为小尾寒羊和蒙古羊杂交羊。在一胎多羔的羔羊中,随机选取1只随母羊生活、饮食母乳的羔羊列入对照组;其他羔羊出生第1天和母羊生活在一起,从第2天起与母羊分离,自由饮用酸化奶,列入酸化奶组(即试验组)。结果表明:(1)酸化奶可促进羔羊生长,在1~60d的试验期内,酸化奶组羔羊的平均日增重为224g/d,比对照组高了61%;(2)酸化奶组羔羊断奶后平均日增重比对照组高29g,提高幅度为10%;(3)饮用酸化奶可保障多羔存活,提高牧场效益。This experiment focused on the effects of feeding acidifed milk on the growth performance of lambs. The basic ewes are small-tailed Han sheep and Mongolian sheep hybrid sheep. Among the lambs with one litter, one lamb lived with the ewe and eat breast milk was selected randomly as the control group. The other lambs lived with the ewes on the frst day of birth, separated from the ewes from the second day, and freely consumed acidifed milk, which were selected as the acidifed milk group （test group）. The results showed that： （1） Feeding acidifed milk can promote the growth of lambs. During the test period of 1-60 days, the average daily weight gain of the acidifed milk group was 224g/d, which was 61% higher than that of the control group; （2） The average daily weight gain of the acidifed milk group after weaning was 29g higher than that of the control group, increase of 10%; （3） Feeding acidifed milk could ensure the survival of multiple lambs and improve the effciency of the pasture.
