Embodiment 1

[0028] In this embodiment, a method for cultivating black-bone chickens with higher production performance, the steps are as follows:

[0029] Step 1, do male parent with Fengxiang iron-footed hemp black-bone chicken parent generation rooster, do female parent with AA chicken parent generation CD, hybridize and produce F1 generation, select and stay the hen that F1 generation has black bone, black skin and black shank;

[0030] Step 2. Use Fengxiang iron-footed hemp silky parent rooster as the male parent, and mate with the F1 generation hen to obtain the F2 generation. Select and retain the male parent's hairy appearance in step 1, black bones, black skin, and black shanks. individual;

[0031] Step 3. F2 generation male and female individuals are cross-fixed and multiplied, and a family is established, and economic traits such as growth rate and egg production performance are improved according to the family and individual selection methods. In addition, appearance traits su...

Embodiment 2

[0035] In this embodiment, a method for cultivating black-bone chickens with high production performance, the steps are as follows:

[0036] Step 1. Use Jinling Tiejia Ma black-bone commercial rooster as the male parent, and Kebao's ancestor D-line hen as the female parent, and crossbreed to produce the F1 generation. The F1 generation is selected to have black bones, black legs, and black skin. the hen;

[0037] Step 2, use Jinling black-bone chicken parent generation cock as the male parent, and mating with the F1 generation hen to obtain the F2 generation, select individuals with black skin and jute feather color traits, and carry out feeding management according to the breeder breeding management method;

[0038] Step 3, cross-fixing and multiplying the male and female individuals obtained in step 2, and forming a family line, and improving the growth rate and egg production performance according to the family line and individual selection methods. In addition, pay attent...

Embodiment 3

[0042] In this embodiment, a method for cultivating black-bone chickens with high production performance, the steps are as follows:

[0043]Step 1. Take Wuding black-bone chicken parental cock as the male parent, use Ross 308 parental hen CD as the female parent, crossbreed to produce the F1 generation, keep the F1 generation hen, and carry out feeding management according to the breeder breeding management method;

[0044] Step 2, do male parent with Wuding black-bone chicken parent generation cock, and F1 generation hen mating, obtain F2 generation, choose to stay the individuality of black bone, black shank, black skin, jute feather color character;

[0045] The male and female individuals obtained in step 3 and step 2 are cross-fixed and multiplied, and a family is established, and the growth rate and egg production performance are improved according to the family and individual selection methods. Pay attention to the selection of jute feather-colored individuals with blac...

Abstract

The invention belongs to the technical field of breeding of poultry, and discloses a method for breeding a new strain of black-bone chickens with higher production performance, which comprises the following steps in sequence: taking a Chinese black-bone chicken as a male parent and a foreign broiler chicken as a female parent, producing F1 generation through hybridization, and retaining a hen having black bone, black shin and black skin characters in the F1 generation; taking the male parent in the step 1 as a male parent to conduct mating with the hen of the F1 generation to produce F2 generation through hybridization, selecting a cock and a hen which have same feather and appearance as that of the male parent in the step 1, as well as the black bone, the black shin and the black skin characters; carrying out intercrossing and propagation to individuals obtained from the step 2, improving the grow speed and the egg producing performance according to a family and individual selection method, laying stress on the black skin, sexual maturity and the feather and the appearance characters; and conducting system breeding of four or more than four generations to obtain the new strain of black-bone chicken. The method obviously promotes the growth speed of the Chinese black-bone chicken at early stage, reduces feed-to-chicken ratio, and improves propagation performance under certain conditions.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to a method for cultivating a new strain of black-bone chicken with higher production performance. Background technique [0002] Black-bone chicken is mainly named for its black bones. It is similar to domestic chicken and belongs to the same family and genus. It is my native chicken breed. According to the "Compendium of Materia Medica": "Black-bone chickens have white-haired black-bones, black-haired black-bones, spotted-haired black-bones, white-skinned black-bones, and those with all black flesh and blood are better for medicine."
