| 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、266.83 kg,差异极显著(P＜0.01);胴体重分别为186.60、125.67 kg,差异极显著(P＜0.01);净骨重分别为39.74、25.00 kg,差异极显著(P＜0.01);净肉重分别为147.84、100.83 kg,差异极显著(P＜0.01);屠宰率分别为51.15％、49.34％,差异显著(P＜0.05);净肉率分别为40.54％、37.66％,差异显著(P＜0.05);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1∶3.73、1:4.03,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.

| Abstract: | For studying the germplasm characteristics 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＜0.01),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. |
