Seed production method of gray-feather meat duck

Abstract

The invention discloses a production method for gray feather meat ducks. The method comprises the steps that 1, Liancheng white ducks and Cherry Valley ducks (SM3) are selected for direct cross, the character is fixed through athwart cross, an F series is obtained, the Liancheng white ducks and the Cherry Valley ducks (SM3) are subjected to reciprocal cross, the character is fixed through athwart cross, and an M series is obtained; 2, an F series breeding family and an M series breeding family are established, and the F series and the M series are reasonably selected and matched through a family selection and individual selection combining method; 3, the F series serves as a male parent, the M series serves as a female parent, and an F1 generation is obtained; 4, the F1 generation serves as the female parent to be backcrossed with the Cherry Valley ducks (SM3), and obtained offsprings are the gray feather meat ducks. On the basis of guaranteeing the advantages of local ducks, the growth speed is increased, the feed conversion ratio is reduced, the carcass weight is increased, and the dressing percentage is increased.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a seed production method of gray-feathered meat ducks. Background technique [0002] my country's duck species are rich in resources, which can be divided into laying ducks, meat ducks and dual-purpose ducks according to their economic uses. In the 1980s, foreign large-scale white-feathered meat ducks were introduced into my country, and they were bred on a large scale in China to adapt to the Chinese consumer market.

In recent years, the consumption market of large white-feathered meat ducks abroad has gradually shrunk, and local duck varieties have gradually expanded their market share due to their unique meat flavor and taste. Due to the small size of local duck breeds, slow gro...

Problems solved by technology

Due to the small size of local duck breeds, slow growth rate, high feed meat ratio, small carcass and other reasons, the breeding, processing and sales of local ducks have hindered the large-scale breeding of local ducks.
