本试验对230日龄武定鸡不同性别和部位的肉质物理特性指标进行了测定分析。结果显示：①性别对230日龄武定鸡的肉质物理特性影响不大,仅在嫩度上母鸡优于公鸡,且差异显著（P〈0.05）;②部位对230日龄武定鸡肉质的物理特性有很明显的影响（P〈0.05）,胸肌的嫩度、贮藏损失、L值、b值均显著高于腿肌,而a值、pH值显著低于腿肌,只有系水率在胸部和腿部间没有显著差异（P〉0.05）;③阉割可以改善武定鸡肉质。

The experiments determined the physical meat indicators on the different genders and parts of 230-day-old Wuding chicken. The results showed：（1）The gender have no large effect on the physical meat prop- erties of 230-day-old Wuding chicken, only the tenderness of hens was higher than cocks, and with significant differences between them （P〈0.05）. （2）The part having large impact on the physical meat properties of 230-day-old Wuding chicken {P〈 0.05}, the tenderness, drip loss, L and b of breast muscle were significantly higher than in the leg muscle, and the a, PH of breast muscle were significantly lower than in the leg muscle, only the water holding capacity in the breast and leg were no significant differences （P〉 0.05）. （3）Castration can im- prove the quality of Wuding chicken.
