Breeding method of gray goose of a kind of three-way hybrid mating line

Abstract

The invention discloses a method for cultivating gray goose of a three-way hybrid mating line, and provides a method for cultivating a gray goose hybrid mating line with high birth weight, fast growth and good meat production performance, comprising the following steps: adopting Xingguo gray Goose male goose and Yangzhou goose female goose were used as breeding materials to obtain the XY synthetic line of Xingyang goose, and then the lion head goose male goose was used as the parent of the male goose, and the XY synthetic line of Xingyang goose was used as the parent of the matching line Goose female parent, after crossing, a three-way hybrid matching line gray goose is obtained. The mating line of Xingshi gray goose cultivated by the breeding method of the present invention has gray feathers of the female goose, and the meat is tender and fragrant. It not only has the heterosis of the egg-type gray goose that lays more eggs, but also has the fast growth rate and the characteristics of the meat-type gray goose. The heterosis of high meat production performance, its high productivity and strong market competitiveness have improved the economic benefits of gray goose production.
