摘　　要：贵德黑裘皮羊引入到甘肃岷县,在放牧加补饲饲养条件下,各生理指标正常,各月龄体重、主要体尺等指标与引入地接近,其生长发育、抗病能力、繁殖性能、耐粗饲等方面表现良好。贵×岷F1和岷县黑裘皮羊相比较,羊的初生重、1月龄、6月龄、1岁龄平均体重,公羔分别比岷县黑裘皮羊公羔提高0.11kg、0.67kg、0.97kg和1.33kg;母羔分别比岷县黑裘皮羊母羔提高0.08kg、0.40kg、1.21kg和.1.65kg。4月龄、6月龄的贵×岷F1羔羊在体斜长、胸围、体高方面都有所提高,数据表明,贵×岷F1杂交一代性能好于岷县黑裘皮羊,在甘肃省岷县生态条件下可以生存、繁殖和发展,并可用于杂交改良岷县黑裘皮羊,提高岷县黑裘皮羊的生产性能。Guide black fur sheep were introduced to Min County, Gansu Province. Under the condition of grazing and supplementary feeding breeding, physiological indexes such as body weight and body size of Guide black fur sheep were similar to the local sheep, while the growth and development, disease resistance, reproductive performance, resistance of crude feed and etc. were better than the local sheep. Compared to Min County black fur sheep, the average body weight of 0-day, 1- month, 6--month and 1--year of male lamb in F1 generation （Min 5〈 Guide） were increased by 0. llkg,0.67kg,0.97kg and1. 33kg, respectively, while the above paraments of female lamb were improved by 0.08kg,0.40kg,1.21kg and 1.65kg. Besides, the body slanting length, chest girth and withers height of hybrid generation were increased. The results showed that the production performance of the first filial generation is better than Min County black fur sheep. Furthermore, the filial generation can be used to improve the production performance of black fur sheep.
