Abstract 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*) of longissimus dorsi. The results showed that gender had no significant effect on protein content, amino acids, pH, water holding capacity, L* or a* (P > 0.05), but significantly influenced fat content, water content shear force and b* (P < 0.05). The longissimus dorsi mucle of Chinese Simmental cow had higher fat content and b* 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.
