【摘要】 随机选择河南固始鸡、福建贡鸡和江西麻鸡各 2 0 0只 ,在相同条件下进行饲养 ,分别于 0、1 4、2 8、42、5 6、70日龄对其生产性能和肉质进行分析比较。结果表明 ,固始鸡的 70日龄平均体重为 1 2 0 4 .2 3± 1 92 .60 g ,料重比为 2 .92 :1 ;贡鸡的上述两项指标分别为 982 .5 4±1 88.92 g和 3.2 2 :1 ;江西麻鸡分别为 1 1 69.30± 2 0 9.2 0和 3.0 4 :1。屠宰率、全净膛率、半净膛率、胸肌率和腿肌率在 3个品种间差异不显著。肌纤维直径以贡鸡最小 ,固始鸡最大。更多还原

【Abstract】 The results in comparative study on the characteristics and meat qualities of three breeds: Gushi Chicken, Fujian Chicken and Jiangxi Chicken proved that Gushi Chicken can get the fastest growth and best feed conversion rate(FCR) under the same management condition, with average body weight 1204.23g and FCR 2.92∶1 at seventy days, and of Fujian Chicken makes 982.54g and 3.22∶1 respectively, and of Jiangxi Chicken makes 1169.30g and 3.04∶1. The dressing percentage, brawn bressing and half-brawn brssing percentage, the chest and leg muscle percentage contrasted no significance, among these three chicken breeds. Muscle fibre diameter of Fujian Chicken was the smallest,and of Gushi Chicken was the highest.更多还原
