摘要: 系统研究经连续4个世代选育的戴云山羊新品系的生产性能, 结果表明:戴云山羊新品系比零世代群体的体重提高幅度为2.26%14.06%, 胸围提高幅度为1.39%4.20%, 体高、体长、胸宽、胸深提高效果不明显;各世代配种率、受胎率均在90%以上;头胎产羔数在1.321.48头、经产产羔数在1.892.12头。Abstract: Productivity of a new Daiyun Goat Strain which consecutively breeded by four generations were researched.Comparing with the generation Zero, the new Daiyun Goat Strain weight has increased from 2.26%to 14.06%, and the chest girth incretion was 1.39%-4.20%, while height at withers, body length, chest width and chest depth have not increased significantly.The breeding rate and conception rate of each generation were all above 90%;and the lambing number of the first-born in each generation were between 1.32-1.48, which of the laterborn in each generations were between 1.89-2.12.
