摘　　要：随机选择6月龄酉州乌羊、本地白山羊和波杂羊公羊各3只,屠宰后进行屠宰性能和肉品质研究.结果表明:1酉州乌羊与本地白山羊生长性状、屠宰性能和肉品质指标均差异不具有统计学意义(p<0.05).2酉州乌羊的体高极显著低于波杂羊(p<0.01),管围显著短于波杂羊(p<0.05).3酉州乌羊的肉骨比高于其他群体,宰后质量、胴体长极显著低于波杂羊(p<0.01),胴体质量、骨质量、净肉质量显著低于波杂羊(p<0.05).4酉州乌羊的皮质量、皮厚、皮张面积、前蹄质量、后蹄质量、肝脏质量、脾脏质量、左肾质量、内脂质量、小肠净质量极显著低于波杂羊(p<0.01),心脏质量、脾脏质量、右肾质量、胃含内容物质量、小肠含内容物质量、小肠长度、大肠含内容物质量、大肠净质量显著低于波杂羊(p<0.05).5酉州乌羊与波杂羊的肉品质指标差异不具有统计学意义(p>0.05).Three 6-month-old male lambs were randomly selected from Youzhou black goats,local white goats and upgrading offspring of Boer goats each,and their carcass quality and meat traits were investigated after slaughtering.The indexes of growth traits,carcass quality and meat traits showed no significant differences between Youzhou black goats and local white goats（p〉0.05）.The height at withers in the Youzhou black goat group was highly significantly lower than that of the upgrading offspring of Boer goat group（p〈0.01）,and the cannon circumference in the Youzhou black goat group was significantly shorter than that of the group of the upgrading offspring of Boer goat（p〈0.05）.Compared with the other groups,the Youzhou black goat had higher meat-bone ratio.Its slaughter weight and carcass length were highly significantly greater than those of the upgrading offspring of Boer goat（p 0.01）,and its carcass weight,bone weight and net meat weight were significantly greater than those of the upgrading offspring of Boer goat（p〈0.05）.Compared with the upgrading offspring of Boer goat,the Youzhou black goat had highly significantly higher skin weight,skin thickness,area of skin,fore-foot weight,hind-foot weight,liver weight,spleen weight,left kidney weight,inner-lipid weight and small intestine net weight（p〈0.01）,and significantly greater heart weight,spleen weight,right kidney weight,content in stomach weight,small intestine content weight,small intestine length,big intestine content weight and big intestine net weight（p〈0.05）.The indexes of meat traits showed no significant differences between the Youzhou black goat and the upgrading offspring of Boer goat（p〉0.05）.
