百宜黑羽鸡外貌特征及生长发育研究

从选育中的1,2世代百宜黑羽鸡的外貌特征、生长性能两个方面对百宜黑羽鸡的部分特征特性进行了研究,结果表明:百宜黑羽鸡具有全黑羽带墨绿色(脚、胫、喙、耳毛为黑色),体形中等,肤白色。2周龄时公母均出现日增重率先升后降,分别由0.048%和0.48%上升到41.72%和37.79%,接着又下降到5.69%和5.06%。百宜母鸡的生长曲线从10周龄开始与公鸡的生长曲线分离,17周龄后母鸡的生长速度明显慢于公鸡。

Study on Appearance Feature of Baiyi Chicken Variety with Black Feather and Its Growth and Development

The appearance feature and growth performance of F1 and F2 of Baiyi chicken with black feather was studied.The results show that the leg,shin,beak and ear hair all is black with blackish green and it has a middle body figure with white skin.The daily gain rate of male and female chicken with two-week age increases first from 0.048% and 0.48% to 41.72% and 37.79% and declines late from 41.72% and 37.79%,to 5.69% and 5.06% respectively.The growth curves of the hen and cock begin to separate from ten-week age and the separation distance between the growth curves of the hen and cock is up to the maximum value when their age is seventeen-week,which expresses that the hen growth rate is obviously lower than that of the cock.
