性别是影响牛肉品质的重要因素。为研究性别对中国西门塔尔牛肉质的影响，对健康无病、发育正常的18月龄中国西门塔尔牛公牛和母牛的背最长肌的肉品质进行测定，肉品质指标包括脂肪、蛋白质、水分、氨基酸、pH值、剪切力、蒸煮损失、压力失水率和肉色（L*、a*和b*）。结果表明：中国西门塔尔牛的性别对蛋白质、氨基酸、pH值、持水力、L*和a*无显著影响（P＞0.05），对脂肪、水分、剪切力和b*值有显著影响（P＜0.05）。中国西门塔尔牛母牛具有较高的脂肪和b*值，较低的剪切力值和水分含量。总体上，中国西门塔尔牛母牛的牛肉适口性更好，嫩度更高，母牛的肉质要优于公牛。

Gender is an important factor influencing beef quality.In order to study the influence of gender on Chinese Simmental cattle, 18-month-old Chinese Simmental bull and cow were chosen and slaughtered for the measurement of fat, protein content, water content, amino acids, pH, shear force, cooking loss, pressing loss and color parameters (L*,a* and b*) oflongissimus dorsi. The results showed that gender had no significant effect on protein content, amino acids, pH, water holding capacity,L* ora* (P> 0.05), but significantly influenced fat content, water content shear force andb* (P < 0.05). The longissimus dorsi mucle of Chinese Simmental cow had higher fat content andb* value, and lower shear force value and fat content than that of the Simmental bull. In conclusion, beef of Chinese Simmental cow had better palatability and improved tenderness, and beef quality of cow was superior to that of the bull.
