摘　　要：对180头生长家牦牛和半血野牦牛的产毛量进行了测定。测定结果,家牦牛1岁1.263±0.239kg/头,2岁1.404±0.329kg/头;3岁1.501±0.326kg/头;半血牦牛相应为1.074±0.308kg/头,1.064±0.336kg/头,1.158±0.410kg/头。其绒毛产量分别为家牦牛0.605±0.143kg/头,0.711±0.216kg/头,0.635±0.246kg/头。半血野牦牛0.556±0.177kg/头,0.418±O.201kg/头,0.453±0.217kg/头。裙毛产量分别为家牦牛0.658±0.137kg/头,0.693 ±0.175kg/头,0.866±0.187kg/头。半血野牦牛0.518±0.211kg/头,0.646±0.257kg/头,O.705±0.258kg/头。结果表明,给家牦牛导入野牦牛血液进行血缘更新,牦牛的产绒、产毛性能未能得到提高。180 Growth domestic yaks and half-blood wild yaks were used to determine the wool gield.The resales were that the wool yield of domestic yaks at the age of one. two and three years were 1.263 ± 0.239,1.404 ± 0.329 and 1.501 ± 0.326 kg, resp, those of half-blood wild yaks were 1.074 ± 0.308,1.064 ±0.336 and 1.158±0.410kg, resp., and the down yield of they were 0.653 ±0.143,0.711 ±0.216,0.653 ±0.246 and 0.556 ± 0.177,0.418 ± 0.201,0.453 ± 0.217kg,resp., and Prone Wool yield of they were 0.658 ±0.137,0.693 ±0.175,0.866 ±0.187 and 0.518 ±0.211,0.646 ±0.257,0.705 ±0.258 kg, resp. The results showed that the wool production performance of domestic yak was not improgved by means of infusion of wild yak blood.
