【Abstract】 The selection and breeding of rapidly feathering strain and slowly feathering strain of Chongren chicken were carried out. The accurate rate of autosexing of the progenies from the combinations of rapidly feathering strain and slowly feathering strain was 98.02%. The influences of feathering gene on the production performance of Chongren chicken such as laying performance, egg quality, growth speed at early stage, semen quality, trait of body size and slaughter property were determined.更多还原
