【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(p0.05).2酉州乌羊的体高极显著低于波杂羊(p0.01),管围显著短于波杂羊(p0.05).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(p0.01),胴体质量、骨质量、净肉质量显著低于波杂羊(p0.05).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(p0.01),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(p0.05).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(p0.05).
[Abstract]:The slaughtering performance and meat quality of 6 month old U Zhou Wu sheep, 3 local white goats and 3 Bo sheep were randomly selected. The results showed that: (1) there was no significant difference in growth traits, slaughter performance and meat quality between Uzhouwu Sheep and Local White Goat (p0.05). 2 the body height of Uzhouwu Sheep was significantly lower than that of Bo Zhouwu Sheep (p0.01). (3) the meat and bone ratio of Youzhou Wu sheep was higher than that of other populations, the postmortem quality and carcass length were significantly lower than those of Bo hetero sheep (p0.01), and the carcass weight and bone quality were significantly lower than those of Bo hetero sheep (p0.01). The net meat quality was significantly lower than that of Bo Zai sheep (p0.05). 4 the skin mass, skin thickness, skin area, front hoof mass, hind hoof mass, liver mass, spleen mass, left kidney mass, internal fat mass of Uzhouwu sheep were significantly lower than those of Bo Zai sheep (p0.05). The net weight of the small intestine was significantly lower than that of the sheep (p0.01), the heart mass, spleen mass, right kidney mass, stomach content mass, small intestine length, large intestine content mass, The net weight of large intestine was significantly lower than that of bow sheep (p0.05). 5 there was no significant difference in meat quality indexes between Youzhou Wu sheep and Bo hetero sheep (p0.05).
