Embodiment

[0038]Selection of sire line: The Canadian Red Polo broiler S01 rooster was crossed with the S08 broiler hen with green feet and hemp feathers bred by Sichuan Daheng Poultry Breeding Co., Ltd. to produce the F1 generation; The F2 generation was produced by backcrossing hens with hens with hemp feathers. In the F2 generation, male and female hens with fast growth were selected for cross-crossing and fixed to obtain the F3 generation. The body weight at 70 days was used as the judgment standard, and the male and hens with green feet and hens with fast growth were selected as the male line to establish the basic group of the B01 line. They were reared in single cages and artificially inseminated. According to the body weight of roosters at 300 days old and the egg production of hens at 300 days old, 80 families were selected and established as the core group of the first generation. According to this selection standard and family coefficient, the subsequent selection was carried o...

Abstract

The invention discloses a breeding method of slaughtering and processing type excellent-quality partridge shank chickens. The breeding method comprises the following steps of through variety introduction and hybrid variety production, constructing an underlying group of a paternal line B01 and a matrilineal line B02, by a genealogical breeding method, maintaining the reproductive performance and improving the growth rate and meat production performance, and through hybridization, culturing slaughtering and processing type excellent-quality partridge shank chicken commodity replacing groups. According to the method, the problems that conventional excellent-quality partridge shank chickens are low in growth rate and poor in meat production performance are solved, in the cultivation process, the specific advantages of the partridge shank chickens of being beautiful in appearance, unique in somatotype, delicious in meat quality and meat taste, high in disease resistance, good to raise and like are selected and reserved, the cultured excellent-quality partridge shank chickens are uniform in appearance, good in meat quality and flavor, high in growth speed, high in meat production performance, and convenient in commercial production and sales, and the breeding method has important significance of meeting requirements of modern chicken processing for excellent-quality chicken variety sources.
