摘　　要：对１７６头各龄家牦牛和半血野牦牛的年产毛量进行了测定。测定结果：家牦牛１岁０．９８±０．２９ｋｇ／头，２岁１．１２±０．２２ｋｇ／头，３一５岁１．１８±０．３８ｋｇ／头，６岁以上０．８８±０．２７ｋｇ／头；半血野牦牛相应为０．９０±０．２０ｋｇ／头，１．０５±０．２７ｋｇ／头，０．６８±０．２８ｋｇ／头，０．９０±０．３８ｋｇ／头；３一５岁家牦牛组的年产毛量极显著高于６岁以上年龄组（Ｐ＜０．０１），同１岁、２岁年龄组的年产毛量差异不显著（Ｐ＞０．０５），２岁与６岁以上年龄组之间呈显著性差异（Ｐ＜０．０５）；半血野牦牛各年龄组的年产毛量差异不显著（Ｐ＞０．０５）；１岁家牦牛公母间，２岁半血野牦牛公母间，年产毛量差异极显著（Ｐ＜０．０１）。Animal hair production for 176 domestic Yaks(DY)and half-wild Yaks(HWY)of several aged-groups was measured.The results showed that the animal hair production perhead DY of one year-old was 0.98±0.29 kg,and that of two year-old 1.21±0.22 kg,threeto five year-old 1.18±0.38kg,six and the elder year-old 0.88±0. 27kg;and the animal hairproductionper head HWY at the sameageswas0.90±0.20,1.05±0.27,0.68±0. 28and0.90± 0.38kg,correspondingly the animal hair production of 3一5year-old DY was highlysignificant higher than that of six and the elder year-old(P<0.01),but no difference was ob-served between one or two year-old DY and the 3一5year-old DY(P>0.05),The productionof two year-old DY was higher than the six and elder year-old ones, No differences were ob-served between the several agedgrowps of HWY animal hair production(P> 0.05 ).Therewas highly significant difference observed between male and fmale HWY at two year-old.
