| 摘 要： | 目的]探讨内蒙古白绒山羊产羔数的遗传规律。方法]对2000-2007年出生的22 721只内蒙古阿尔巴斯白绒山羊羔羊的初生重及3 044只母本羊产羔数进行统计分析。结果]最小二乘方差分析表明,性别、胎次和出生类型对羔羊初生重有显著影响;约束性最大似然法分析表明,胎次、群体和母体效应对产羔数有显著影响。羔羊初生重遗传力单羔为0.16,双羔为0.40,全部为0.17。结论]该研究为下一步建立内蒙古白绒山羊高繁殖性能品系奠定了一定的基础。

| Abstract: | Objective] The study aimed to explore the genetic law of litter size of Inner Mongolia White Cashmere Goat.Method] The birth weights of 22 721 lambs and litter sizes of 3 044 female goats were statistically analyzed.Result]The least square variance analysis results showed that sex,parity and birth type had significant effects on lamb birth weight.Restricted maximum likelihood analysis indicated that parity,population effect and maternal effect influenced litter size of female goats significantly.The birt... |
