中文摘要：

为研究昌台牦牛的产肉性能．了解昌台牦牛种质资源特性．对8头（5公3母）成年昌台牦牛进行了屠宰测定。结果表明，成年昌台公、母牦牛宰前重分别为364.32、266．83kg，差异极显著（P〈0.01）；胴体重分别为186．60、125．67kg，差异极显著（P〈O．01）；净骨重分别为39．74、25．00kg，差异极显著（P（0．01）；净肉重分别为147．84、100．83kg．差异极显著（P〈0．01）：屠宰率分别为51．15％、49.34％，差异显著（P〈O.05）：净肉率分别为40．54％、37．66％，差异显著（P〈O．05）；胴体产肉率分别为79．29％、80．24％，差异不显著（P〉0．05）；骨肉比分别为l：3．73、l：4．03，差异极显著（P〈0．01）。昌台牦牛生长发育性能较好．产肉性能潜力大．应当进一步挖掘选育，加快其选育进程。

英文摘要：

For studying the germplasm charactedsUcs and carcass traits of Changtai yak, 8 adult yaks （5 male, 3 female） were selected and tested. The results showed that the pre-slaughter weight of the adult male and female Changtai yak was 364.32 and 266.83 kg, respectively, which presented extremely significant difference （P〈0.01）. The carcass weight, net bone weight net meat weight, and the ratio of bone to meat also showed extremely significant difference （P〈O.01）, which were 186.60 and 125.67 kg, 39.74 and 25.00 kg, 147.84 and 100.83 kg, 1：3.73 and 1： 4.03, respectively. The dressing percentage had significant difference which was 51.15% and 49.34%, respectively （P〈0.05）. The neat meat percentage and carcass meat production rate showed no significant difference which were 40.54% and 37.66%, 79.29% and 80.24%, respectively （P〉0.05）. It indicated that Changtai yak has better growth performance and meat performance potential, and worth of further studying and breeding.
