中文摘要：

选择4、6、8月龄巴美肉羊各20只,按性别分类并与同月龄的小尾寒羊、苏尼特羊做对比屠宰实验,分别测定其背最长肌的色泽、嫩度、p H和熟肉率,研究基于性别因素的巴美肉羊肉用品质特性。结果表明：4月龄巴美母羊和巴美公羊背最长肌未表现出色泽的差异。6月龄巴美母羊的L＊值显著大于苏尼特母羊的L＊值,而a＊值在6月龄和8月龄时都显著大于对照组母羊和公羊的a＊值（P〈0.05）。同时,巴美母羊和巴美公羊在4月龄、6月龄和8月龄的剪切力值分别显著小于寒羊母羊、苏尼特母羊和寒羊公羊、苏尼特公羊的剪切力值（P〈0.05）。同时,8月龄巴美母羊和巴美公羊的熟肉率显著大于苏尼特母羊和公羊的熟肉率（P〈0.05）,而寒羊母羊和公羊的熟肉率虽然也分别小于巴美母羊和公羊的熟肉率,但并不显著（P〉0.05）。各试验组的pH_24值随着月龄增加呈先上升后下降趋势,但并不显著（P〉0.05）,而熟肉率却呈现出先显著增加后显著下降趋势（P〈0.05）。巴美母羊和公羊在6月龄时表现出了p H_24值的优势。同时,巴美母羊和巴美公羊的剪切力值随着月龄增加却在一直下降,表明其月龄因素还暂未影响到其剪切力值,因此,有待于肉品研究者进一步扩大月龄范围进行研究。

英文摘要：

Bamei lamb, which has little studies, had significant research value because it was a new species that cultivated in Inner Mongolia. In this experiment, Bamei lamb at 4 months-of-age, 6 months-of-age and 8 months-of-age were chosed, and made a slaughter experiment with Small tailed sheep and Sunit lamb at same ageb. According to the comparison of colour, tenderness, pH and cooked rate from Longissimus Dorsi of different gender, the result showed that no significant difference on colour was found between female and male of Bamei lamb at 4 months-of-age. Female of Bamei had higher L＊ than that of Sunit lamb whereas the value of a＊ in meat from Bamei was higher than that of Small tailed sheep and Sunit lamb at both 6 months-of-age and 8 months-of-age （P〈0.05）. Meanwhile, the shear force in meat from Bamei lamb was lower than that of Small tailed sheep and Sunit lamb at 4 months-of-age, 6 months-of-age and 8 months-of-age, respectively （P〈 0.05）. Moreover, both female and male of Bamei had higher cooked rate than that of Sunit lamb whereas it was similar to the parameter from Small tailed sheep （P〉O.05）. The value of pH24 in these （P〈0.05）, three lamb breeds increased from 4 months-of-age whereas decreased from 6 months-of-age （P〉0.05）, however, the cooked rate exhibited the contrary tendency （P〈0.05）. Moreover, the shear force in both female and male of Bamei decreased from 4 months-of-age to 8 months-of-age, which exhibited that the age of slaughter did not affect the value of shear force. Therefore, the parameter of shear force need more deep research according to the expansion of the slaughter age.
