摘要
本研究利用南江黄羊系统的育种资料 ,采用公畜模型和母女回归对生长发育性状、繁殖性状及一些质量性状的遗传参数作了测定 ,结果表明 :生长发育性状属中等遗传力 ,范围 0 1 8～ 0 89,其中日增重遗传力为 0 39～ 0 4 4;繁殖性状的遗传力除初胎产羔率的遗传力为 0 0 2外 ,其余各胎次的遗传力为 0 1 8～0 4 6 ,属中等遗传力 ;但各胎次产羔率的重复力仅为 0 0 6 ;
In the essay,taking advantage of Nanjiang Yellow Goat systematization breed materials and using the sir-pattern and daughter-dam methods,determined the genetic parameter of the growth and reproductive and quality traits.The results showed that the heritabilities of the growth traits were medium,the extent was 0.18～0.89.The heritability of the daily gain was 0.39～0.44.The heritability of the reproductive was 0.18～0.46.But the repeatability of the presentation lambing rate was 0.06.The most traits were significance relative.
