| 摘 要： | [Objective] The aim of this study was to explore the genetic law of litter size of Inner Mongolia Cashmere Goat.[Method] A total of 22 721 litter records from 3 044 mothers were statistically analyzed.[Result] As shown by the least square variance analysis,the sex,parity and birth type had significant effect on lamb birth weight.As indicated by restricted maximum likelihood method,the parity,population and maternal effect influenced litter size significantly.The birth weight heritability of single lamb,twins and total was 0.16,0.40 and 0.17,respectively.[Conclusion] The study provided a certain basis for the establishment of Inner Mongolia Cashmere Goat line with superior reproductive performance.

[Method] A total of 22 721 litter records from 3 044 mothers were statistically analyzed.

As indicated by restricted maximum likelihood method, the parity, population and maternal effect influenced litter size significantly. The birth weight heritability of single lamb, twins and total was 0.16, 0.40 and 0.17, respectively.
