摘　　要：对1997—2002年间放牧条件下中卫山羊够毛期日龄、体重和毛股弯曲数等进行了研究。结果表明,中卫山羊公羔羊够毛期平均日龄、体重均略高于母羔羊,平均毛股弯曲数低于母羔羊;中卫山羊羔羊够毛期日龄的长短与其体重的大小及毛股弯曲数的多少存在着一定的关系,即中卫山羊羔羊够毛期日龄越长,体重越小,毛股弯曲数越多。The age, weight and number of hair strands bend of Zhongwei goat under the condition of grazing from 1997 to 2002 were studied. The results showed that average day-age and body weight of Zhongwei goat male lambs in Goumao period were slightly higher than the female lamb,and the average number of hair strands bend was lower than the female lamb. Furthermore, the day-age of Zhongwei goat in Goumao period had a certain relationship with the weight and the number of hair strands bend, that was the longer the day-age was in Goumao period, and the smaller the weight was, the more the number of hair strands bend was.
