摘　　要：对野生盘羊与纯巴什拜羊杂种后代的生长发育、总繁殖率、常见病发病率、抗寒能力等适应性性状与纯巴什拜羊进行了比较。结果表明,杂种一代羊的适应性较差,而回交二代羊的适应性(其总繁殖率105%,4.5月龄体重达35.8kg,常见病发病率3.3%)最好,杂交效果明显,是培育瘦肉型巴什拜羊新品系的主要组合。The purpose of this study was to compare the growth and development,total reproduction rate, percent infection of common diseases,cold resistance and other adaptive traits of wild argali and hybrid off- spring of pure Bashibai sheep with those of pure Bashibai sheep. The result showed that the adaptive traits of first generation of hybrid sheep were poor, however, the second backcross generation sheep have the best adaptability （105 % of its total fertility rate,weight was up to 35.8 kg for 4.5 months,the percent infection of common diseases was 3.3%）,the hybrid effect was performed obviously,which was the main combina- tion for developing new lines of lean sheep bashibai.
