Problems solved by technology

However, the traditional silky chicken is small in size, its adult weight is only more than 1 kg, its viability is weak, its egg production rate is low, and its weak points such as strong nesting ability affect the development effect, and it is far from meeting the needs of the market.
At the same time, it is difficult to carry out large-scale breeding and promotion
Aiming at the problems in production, many researchers tried to us

Embodiment 1

[0013] The breeding method of the fast-growing type silky chicken new strain in the present embodiment, this breeding method is carried out as follows:

[0014] (1) Using Taihe black-bone chicken as the material, the "I" gene was eliminated by the method of test cross, and then only the chromogen gene "C" was selected, and the oxidase gene "0" was deleted, without inhibition The feather color genotype of Taihe silky chicken male line with pigment gene "I" is "iiCCooPPAA".

[0015] (2) Take the male line of Taihe black-bone chicken after breeding and purification as the male parent, and cross with other fast-growing yellow-skinned chicken breeds (containing the "Id" gene on the sex chromosome) as the female parent. The skin color of the F1 generation can be white to distinguish between male and female. Male chickens with yellow skin (eliminated) and female chickens with black skin (seeds retained) were backcrossed with the F1 generation hen as the female parent, and the Taihe s...

Embodiment 2

[0021] The bred fast-growing silky chicken can be used for hybridization with other chicken breeds to form a complete set, which can be directly used for production.

[0022] (1) Using the fast-growing new line of silky-feather silky chicken as the male parent to carry out binary crossing with the new line of high-yielding silky-feather silky-bone chicken, F1 can all show the characteristics of silky feather, black skin and black bone.

[0023]

[0024] (2) Use the new line of fast-growing silky chicken as the male parent, and the black-legged or green-legged chicken breed (containing the "Id" gene on the sex chromosome) as the female parent. bone.

[0025]

[0026] The yellow shank chicken species of the present invention can be Xianju chicken, Xiaoshan chicken, Beijing oil chicken, etc., and the black shank chicken species can be Gushi chicken, Langshan chicken, etc.

[0027] The above-mentioned facts illustrate that the silky chicken with silky feathers cultivated by...

Abstract

The invention relates to a method for breeding a fast-growing silkie chicken line. In the method, a Taihe black-bone chicken taken as a male parent and a fast-growing yellow-skin or white-skin chicken taken as a female parent are hybridized so as to generate an F1, the Taihe black-bone chicken taken as a male parent is backcrossed with female in the F1 generation, and the fast-growing silkie chicken line is obtained through purification. The bred silkie chickens can realize stable inheritance, can be directly applied to production and also can be hybridized with corresponding local chickens. Therefore, excellent-characteristic chicken lines are bred.

Description

technical field [0001] The invention relates to a method for cultivating chickens, in particular to a method for cultivating fast-growing silky chicken strains. Background technique [0002] my country's local chicken breeds are rich in resources, and many local chicken breeds have excellent traits that foreign chicken breeds cannot match. Silkie, as a wonderful work in the local chicken breed family, is a unique medicinal bird in my country. However, the traditional silky chicken is small in size, its adult weight is only more than 1 kg, its viability is weak, its egg production rate is low, and its weak points such as strong nesting ability affect the development effect, and it is far from meeting the needs of the market. . It is also difficult to carry out large-scale breeding and promotion. Aiming at the problems in production, many researchers tried to use Taihe silky chickens to breed new fast-growing silky strains. In terms of breeding methods, they all used unplan...
