野生盘羊与巴什拜羊的杂交研究

对野生盘羊与巴什拜羊进行导入杂交,通过对带有1/2、1/4野血的杂种羔羊生长状况、肉用性能、尾型、外形体质和毛质的变化进行观察及测定,并与纯巴什拜羔羊进行了比较.研究结果表明:第一、二代杂种羔羊在胚胎期四肢生长强度比躯体强,这一点继承了盘羊的遗传特性,从初生到断奶期间躯体的生长速度和强度较好,这方面继承了巴什拜羊早期生长发育快的遗传特征,在体尺指标和外部特征上野生基因占优势,毛质和毛的颜色基因巴什拜羊占优势.研究为今后家养绵羊与野生盘羊杂交和充分利用野生动物资源,提供科学数据.

Study on Hybridication of Wild Argali and Bashibai Sheep

In this paper,the investigation on hybridization of wild argali and Bashibai sheep was carried out on the basis of growth condition,properties for meat,tail shape,appearance physique and change of hair quality of the hybrid lamb with 1/2 and 1/4 of wild blood,compared with that of the purebred Bashibai sheep.The results suggested that the growth intensity of the four legs of the hybrid lambs from 1st and 2nd generation at placenta stage was stronger than the body,which succeeded the former' genetic properties.The body of argali grows well from the birthday to the weaning,which succeeded the former'genetic properties.The study results provided the scientific data for the hybridization between domestic sheep and wild argali.
