Problems solved by technology

At present, in the production of local chickens such as jute (hemp) feather chickens, most of them increase their growth speed by introducing fast genes or using fast large breed chickens for supporting production, but using this method has resulted in a significant reduction in the meat quality and flavor of local chickens

Embodiment 1

[0011] The breeding method of blue shank recessive white feather native chicken, this breeding method is carried out according to the following steps:

[0012] (1) select the blue-shin white-feathered chicken mutated in the blue-shin yellow (hemp) local chicken breed;

[0013] (2) male and female self-propagation, select individuals with green shins and pure white feathers among their offspring;

[0014] (3) carrying out side crossing to the pure white feather chicken in step (2), rejecting dominant white feather individuals and other colored feather individuals isolated;

[0015] (4) Steps (2) and (3) were repeated until the inheritance was stable, and a new strain of local chicken with blue-shank recessive white feathers was bred.

Embodiment 2

[0017] The breeding method of black shank recessive white feather native chicken, this breeding method is carried out according to the following steps:

[0018] (1) select the black shank white feather chicken mutated in the black shank yellow (hemp) feather local chicken breed;

[0019] (2) Self-propagation of male and female, select individuals with black shanks and pure white feathers among their offspring;

[0020] (3) Carry out side crossing to the pure white feather chicken in step (2), get rid of dominant white feather individual and other colored feather individuals isolated;

[0021] (4) Steps (2) and (3) were repeated until the inheritance was stable, and a new strain of local chicken with black shanks and recessive white feathers was bred.

Embodiment 3

[0023] The breeding method of the yellow shank recessive white feather local chicken, the breeding method is carried out according to the following steps:

[0024] (1) select the yellow shank white feather chicken mutated in the yellow shank yellow (hemp) feather local chicken breed;

[0025] (2) Self-propagation of male and female, select individuals with yellow shanks and pure white feathers among their offspring;

[0026] (3) Carry out side crossing to the pure white feather chicken in step (2), get rid of dominant white feather individual and other colored feather individuals isolated;

[0027] (4) Steps (2) and (3) were repeated until the inheritance was stable, and a new strain of local chicken with yellow shanks and recessive white feathers was bred.

Abstract

The breeding process of chicken variety with green (black or yellow) shank and recessive white feather includes the following steps: selecting mutant green (black or yellow) shank and white feather chicken from local green (black or yellow) shank yellow feather variety; self reproduction and selecting green (black or yellow) shank and pure white feather chicken individuals; test crossing the pure white feather chicken, eliminating dominant white feather chicken individuals and separating colored feather individuals; repeated the above said steps to stabilize genetic characteristic and to obtain new local chicken variety of high-yield variety with green (black or yellow) shank and recessive white feather.

Description

technical field [0001] The invention relates to a method for breeding chickens, in particular to a method for breeding local chickens with blue shanks, black shanks or yellow shanks with recessive white feathers. Background technique [0002] There are many local chicken breeds in our country, and there are 27 chicken breeds listed in "China Poultry Variety Resources". Its meat is tender and delicious, the soup is mellow and nutritious. At present, in the production of local chickens such as jute (hemp) feather chickens, most of them increase their growth speed by introducing fast and large genes or using fast and large breed chickens for supporting production, but using this method has resulted in a significant reduction in the meat quality and flavor of local chickens . Contents of the invention [0003] The object of the present invention is to provide a breeding method for local chicken with blue shank, black shank or yellow shank recessive white feather, so as to pr...
