Method for producing seed of a terminal paternal line of white-feathered va-ghai chicken complete line

Abstract

The application discloses a terminal paternal white-feathered Anyi Va-Grey chicken breeding method, and relates to the technical field of poultry genetic breeding and reproduction. The application obtains the first paternal stable genetic black-feathered black-bone chicken by crossbreeding of the grey-feathered Anyi Va-Grey chicken and the black-feathered Xuefeng black-bone chicken; the terminal paternal stable genetic white-feathered black-bone chicken is obtained by crossbreeding of the grey-white-feathered Anyi Va-Grey chicken and the white-feathered Xuefeng black-bone chicken; the F1 hybrid hens obtained by crossbreeding of the first paternal chicken and other mature line hens are crossbred with the terminal paternal chicken to obtain the commercial generation Va-Grey chicken. The application completely solves the problem of seed source loss caused by the original seed supply of the Anyi Va-Grey chicken, and solves the problems of poor stress resistance, poor meat quality and easy reverse research and development of the simple binary hybrid. The mature line is used to improve the growth speed and the reproductive performance, the demand of variety protection and industrialization is considered, the matching mode is difficult to be reverse imitated, and reliable technical support is provided for industrial standardization.
