Breeding method of low-speed type extra-superior yellow-feather local chickens

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of poultry genetics and breeding, in particular to the technical field of matching slow-speed super-high-quality broiler chickens. Background technique [0002] In most areas of my country, especially in Guangdong and Guangxi, consumers prefer to eat Sanhuang native chicken with a long growth cycle, which has yellow feet, yellow feathers, and yellow beak. Although the traditional three-yellow chicken in Guangxi has the characteristics of thin skin and fragrant meat, it generally has the disadvantages of low egg production rate, brooding, long growth cycle, and high feed-to-meat ratio, and its price is relatively high, which is unaffordable for ordinary consumers. Contents of the invention [0003] The present invention provides a method for cultivating slow-speed super-high-quality yellow-feathered native chickens with fast growth speed, good meat quality and increased egg production, including grandparent...
