摘  要：
选择4、6、8月龄巴美肉羊、小尾寒羊、苏尼特羊公羊和母羊各10只进行屠宰实验,分别分析其屠宰性能和胴体质量,最终确定不同性别的巴美肉羊是否具有优越性。结果表明:4月龄巴美母羊的屠宰率显著大于巴美公羊(P<0.05),眼肌面积显著大于巴美公羊及小尾寒羊和苏尼特羊各性别组(P<0.05);6月龄巴美公羊的屠宰率显著大于小尾寒羊公羊(P<0.05),眼肌面积显著大于巴美母羊;同时,6月龄和8月龄巴美公羊的眼肌面积和背肉厚均分别显著大于同月龄小尾寒羊和苏尼特羊各性别组(P<0.05)。巴美公羊和巴美母羊的屠宰率从4月龄到6月龄显著增加(P<0.05),而净肉率从4月龄到8月龄持续显著增加(P<0.05),巴美母羊的眼肌面积和巴美公羊的背肉厚从4月龄到8月龄持续显著增加(P<0.05),而巴美公羊的眼肌面积和巴美母羊的背肉厚仅从4月龄到6月龄显著增加(P<0.05)。

摘  要：
Bameilamb,a new species cultivated in Inner Mongolia,is of significant value for research.In the current study,Bamei,Small-Tailed Han and Sunit lambs at 4,6 and 8 months of age were chosen.A slaughter experiment with 10 lambs of each sex for each breed was conducted.Comparison of slaughtering characteristics and carcass quality between both sexes was carried out as well.Dressing percentage in female Bamei lambs was higher than in male ones at the age of 4 months(P < 0.05).Meanwhile,female Bamei lambs had larger loin eye area than did their male counterparts and both sexes of the other lamb breeds at the age of 4 months(P < 0.05).Six-month-old male Bamei lambs had significantly higher dressing percentage than did their Small-Tailed Han counterparts(P < 0.05) and presented significantly larger loin eye area than did theirfemale counterparts from the same breed.Meanwhile,male Bamei lambs aged 6 and 8 months had significantly higher levels of loin eye area and back meat thickness than did male and female Small-Tailed Han and Sunit lambs of the same ages,respectively(P < 0.05).As the age increased,dressing percentage in both genders of Bamei was significantly increased from 4 to 6 months old(P < 0.05),and pure meat percentage was significantly increased from 4 to 8 months old(P < 0.05).Moreover,loin eye area in female Bamei lambs and back meat thickness in male Bamei lambs both from 4 to8 months old were also significantly increased(P < 0.05).However,a significant increase in loin eye area and back meat thickness was observed for male and female Bamei lambs from 4 to 6 months,respectively(P < 0.05).
