Problems solved by technology

At present, in the production of local chickens, most of them increase the growth rate of local chickens by introducing fast large gene bloodlines or using fast large breed chickens for supporting production, but the quality and flavor of chicken (egg) are reduced, and it is impossible to achieve sex separation of chicks

Embodiment 1

[0013] The cultivation method of the new strain of cross-spotted shallow reed chicken in the present embodiment, the cultivation method is carried out in the following steps:

[0014] (1) Select male and female hens with cross-spotted light reed flower feather color mutated from local chicken breeds;

[0015] (2) Male and female self-propagation or transversal fixation after importing high-yielding laying hen blood sources, and selecting cross-spotted light reed flower feather color male and female hens from their offspring;

[0016] (3) Carry out lateral cross identification and screening of the sex-linked genetic genes of the above-mentioned light-spotted reed, remove the heterozygous individuals of the light-spotted reed gene, and select homozygous individuals;

[0017] (4) Carry out family selection, individual selection, etc. on the homozygous horizontal-spotted light reed male and female chickens to improve their uniformity and production performance;

[0018] (5) Steps...

Embodiment 2

[0020] The method for cultivating new strains of cross-spotted light reed chicken in the present embodiment, the cultivation method is carried out according to the following steps:

[0021] (1) Select male and female hens with cross-spotted light reed flower feather color mutated from local chicken breeds;

[0022] (2) Male and female self-propagation or transversal fixation after importing high-yielding laying hen blood sources, and selecting cross-spotted light reed flower feather color male and female hens from their offspring;

[0023] (3) Carry out lateral cross identification and screening of the sex-linked genetic genes of the above-mentioned light-spotted reed, remove the heterozygous individuals of the light-spotted reed gene, and select homozygous individuals;

[0024] (4) Carry out family breeding and individual selection on the homozygous cross-spotted light reed flower feather male and hen to improve their production performance;

[0025] (5) Steps (3) and (4) ar...

Abstract

The invention relates to a method for cultivating a new strain of cross-spotted light reed chicken. The steps are: (1) selecting male and female chickens with cross-spotted light reed flower feather color mutated from local chicken breeds; (2) male and female self-propagation or After introducing high-yielding laying hens, cross-crossing was fixed, and male and female chickens with feather color were selected from the offspring; (3) The above-mentioned sex-linked genetic genes of A. Gene heterozygous individuals, select homozygous individuals; (4) carry out family selection and individual selection on homozygous cross-spotted light reed males and hens to improve their uniformity and production performance; (5) Steps (3) and (4) are repeated until the cross-spotted reed gene is stably inherited, and a new strain of cross-spotted light reed chicken is bred. The new strain of high-yield laying hens bred by the present invention is used as the female parent, and it is crossed with other local chickens with feather colors. The F1 generation can be sexed. appearance, and its two-line set can be used for eggs, and the three-line set can be used for meat.

Description

technical field [0001] The invention relates to a method for cultivating chickens, in particular to a method for cultivating a new strain of cross-spotted light reed chicken. Background technique [0002] There are many varieties of local chickens in my country, with rich genetic genes for feather color traits, tender meat, delicious meat, mellow soup, rich nutrition and other characteristics (sex). There are 27 chicken breeds listed only in the "Resources of Poultry Breeds in China". Among these breeds, there are individual mutant individuals with the following characteristics: the main body of the feathers is white feathers in the shape of horizontal-spotted light reeds, and the horizontal-spotted light-spotted reeds gene is located in the sex Chromosomally, there is a dominant sex-linked inheritance. At present, in the production of local chickens, most of them increase the growth rate of local chickens by introducing fast large-scale gene bloodlines or supporting produc...
