Example Embodiment

[0016] A further description will be given below in conjunction with specific embodiments.

[0017] The method for breeding high-quality ducks with white feathers and black beaks of the present invention is characterized in that it comprises the following steps:

[0018] (1) Select Liancheng White Duck and Cherry Valley Duck SM3 for hybridization to produce F 1 Generation; F 1 99% of the plumage in the generation is brown;

[0019] (2) In F 1 Ducks selected from the generation have "black mouth and black feet" appearance traits, and the duck cross-crossing with a weight of 2.2-2.5kg before delivery starts to produce F 2 generation;

[0020] Table 1 shows the orthogonal F of Liancheng White Duck and Cherry Valley Duck 2 Summary of appearance features:

[0021] Table 1

[0022]

[0023] In Table 1, the hybrid offspring of Liancheng White Duck♀ and Cherry Valley Duck♂ were cross-crossed after selecting the appearance traits of "black mouth, black feet" and adult weight. If individuals with ...

Abstract

The invention discloses a white-feather black-beak high-quality duck breeding method. The method comprises the following steps: (1) Liancheng white ducks and Cherry Valley ducks (SM3) are selected and subjected to hybridization, such that an F1 generation is obtained; (2) ducks with specific appearance characteristics and qualified weights before egg-laying maturity are selected from the F1 generation, and are subjected to crossing, such that an F2 generation is obtained; (3) ducks with specific appearance characteristics and qualified weights before egg-laying maturity are selected from the F2 generation, and are subjected to crossing, such that an F3 generation is obtained; (4) the selection and crossing procedures are continued to be circulated until all individuals in an obtained Fn generation have the appearance characteristics of white feather, black beak and black feet, and the weights before egg-laying maturity reach 2.2-2.5kg; (5) the Fn generation is adopted as a base population, and F line and M line breeding populations are established; the F line and M line are further selected with a family selection method; (6) the F line is adopted as a male parent, and the M line is adopted as a female parent, and an obtained offspring is the duck provided by the invention. According to the invention, on a basis that local duck advantages are ensured; growth speed is improved; feed conversion ratio is improved; and carcass weight is increased.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a method for breeding high-quality ducks with white feathers and black beaks. 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 duck varieties were introduced into my country, and were raised in a large scale in China to adapt to the Chinese consumer market. With the development of the economy and the improvement of people's living standards, people will naturally put forward new goals and requirements for the quality, flavor and mouthfeel of duck meat. 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...
