摘要
本试验以740只1日龄慢羽蛋鸡为材料，对裸脊鸡背羽生长发育及其生产性能进进了研究。结果表明：（1）裸背鸡脊羽生长发育明显迟缓于非裸背鸡，在5周龄时即可区分之；（2）裸背鸡比非裸省鸡蛋大，蛋白品质好，但其早期生长慢，血斑率高。
740 slow-feathering chicks from white shell strain were tested to investigate the characteristics of the bare-backed trait and its effect on the performace. The results showed that: 1) The back feathering's growth of the barebacked chickens,as obviously slower than of non-bare backed ones. They could be distinguished according to the back feathering at 5 weeks of age; 2) The barebacked gene (K°) had the effect of increasing the egg size, egg white weight and percentage of blood spots in eggs and lowering the rate of early growth.
