| 摘 要： | 试验系统研究了经连续4个世代选育的戴云山羊新品系的繁殖性能。结果表明，各世代配种率、受胎率均在90％以上；头胎母羊产羔数在1．32～1．48头之间、经产母羊产羔数在1．89～2．12头之间；头胎初生重为1．69～1．77kg，经产为1．47～1．58kg。遗传改良效果为：各世代母羊的配种率与受胎率都得到了一定的改善；产羔数提高约0．2头；各世代羔羊的初生重随着产羔数的增加而减少。

| Abstract: | The experiment was conducted to study the reproductive performances of new strains of Daiyun Goat which were consecutively bred for 4 generations. The results show that the jointing rate and conception rate of each generation were all above 90%; the number of first-born ewes lambing were 1.32 to 1.48, that of parous ewes lambing were between 1.89 and 2.12; the initial weight of lambs of first-born ewes were 1.69 kg to 1.77kg, and that of the parous lambs were 1.47 kg to 1.58kg. The genetic improvement effect showed that the jointing rate and conception rate of ewes of each generation have improved; the lambing number increased about 0.2; and the birth weight of lambs of each generation decreased with the increase of lambing number. |
