The invention relates to the field of
fowl breeding, in particular to the matching technical field of low-speed type extra-superior
broiler chickens. The method relates to
progenitor generations, parent generations and commodity generations. The method comprises the steps that as for the
progenitor generations, cocks and hens of Guangxi sanhuang chickens are selected, and cocks of short-foot yellow chickens and hens of low-speed recessive white-
feather chickens are selected for constituting first male lines and female lines; as for the parent generations, the cocks of the short-foot yellow chickens and the hens of the recessive white-
feather chickens hybridize, and F1-generation yellow-
feather chickens are obtained; as for the commodity generations, the cocks of the Guangxi sanhuang chickens and the hens of the F1-generation yellow-feather chickens hybridize, and the F2-generation slow-speed extra-superior yellow-feather local chickens are obtained. The yellow-feather local chickens bred in the method not only can keep body types and appearances of traditional yellow-feather local chickens, but also can keep taste of chicken and eggs, and production cost can be greatly reduced. Compared with the traditional yellow-feather local chickens,
growth speed is increased by more than 30%,
egg laying capacity of the parent generations is increased by more than 26%, the rate of survival is increased by more than 3.5%, the
feed conversion ratio is reduced by more than 0.17%, and the defects that breeding hens have high brooding capacity and the low laying rate are overcome. In addition, the yellow-feather local chickens bred in the method has delicate meat quality and good mouth feel, breeding profits are increased, and further development of the low-speed type extra-superior chicken industry in China is promoted.
