羽速基因对莱芜黑鸡早期生长速度和蛋用性能的影响

Abstract

Abstract: One-day-old chickens were divided into the rapid feathering group and the slow feathering group according to the feather speed gene.The effect of the feather speed gene on early growth and production performance of Laiwu black chicks was studied. The results showed that some effect on early growth of feather speed gene. Day old weight and 2，4，7，10-week body weight of the rapid feathering group was significant higher than that of the slow feathering group. But there have no significant differences on production performance.

Key words: feather speed gene; Laiwu black chicks; early growth; production performance
