江西余干黑羽乌鸡肉用性能初步研究

余干黑羽乌鸡是我国优良地方品种，具有黑羽、乌皮、乌肉、乌骨的“全乌”特征，属珍稀的地方品种资源。为进一步研究余干黑羽乌鸡的种质特性，我们采用随机抽样的方法对产蛋期末的余干黑羽乌鸡进行了肉用性能和肉质测定的研究，并与我国著名的乌鸡品种─—泰和鸡比较。结果表明：余干黑羽乌鸡肉用性能良好，骨骼结构和载肉量比泰和鸡要好。余干黑羽乌鸡的屠宰率达９２％，半净膛率为８５％，全净膛率为６５％，且营养丰富，蛋白质含量高，富含多种维生素和有益人体的无机元素，氨基酸种类齐全，含量较泰和鸡高，特别是胆固醇含量非常低，低于泰和鸡的２１３％。为进一步开发利用余干黑羽乌鸡营养滋补和药用价值提供科学依据。
