Problems solved by technology

Using conventional family breeding methods to improve early growth speed and egg production performance requires a large investment, and the genetic progress of early growth speed obtained every year is only a few tens of grams, and the genetic progress of egg production is only a few eggs, so it is urgent in production practice. There is a need for a simple and practical method that can increase the early growth rate and increase the egg production performance of breeders in a short period of time

Embodiment 1

[0026] This embodiment is a method for cultivating a new strain of black-bone chicken with higher production performance, and the steps are as follows:

[0027] Step 1. Use Fengxiang black-bone chicken as the male parent, and use the AA chicken parent generation CD as the female parent, and crossbreed to produce the F1 generation. Foreign broiler parental CDs generally contain some recessive white feathers, so 20-28% of chickens with jute feathers will appear in the F1 generation; Skin; black / blue shanks are inherited in a sex-linked recessive manner, so hens show black / blue shanks and roosters show white shanks. Individuals with black skin, black bones, and jute feathers were selected to remain in the F1 generation;

[0028] Step 2. Cross-cross fixation and multiplication of the male and female individuals obtained from the F1 generation will separate the black-boned and black-legged populations with four colors of jute feathers, recessive white feathers, black feathers, and...

Embodiment 2

[0032] In this embodiment, a method for cultivating a new strain of black-bone chicken with high production performance, the steps are as follows:

[0033] Step 1. Use Jinling silky chicken as the male parent, and Kebao parent hen CD as the female parent, and crossbreed to produce the F1 generation. The F1 generation contains 50% of the Kebao pedigree, and because the parental CD of the Kebao contains some recessive white feather genes, the F1 generation has 30%-38% jute feather chickens; 78% of the chickens showed black bones and black skin; the black shank trait was a sex-linked recessive inheritance method, so hens showed black / blue shanks, and roosters showed white shanks. Individuals with black skin, black bones, and jute feathers were selected to remain in the F1 generation;

[0034]Step 2. Cross-cross the male and female hens with jute feather color, black bone and black skin in the F1 generation, and the black bone, black skin and black leg groups with jute feather, r...

Embodiment 3

[0038] In this embodiment, a method for cultivating a new strain of black-bone chicken with high production performance, the steps are as follows:

[0039] Step 1. Take Wuding silky chicken as the male parent, and use the Ross parent CD as the female parent, and crossbreed to produce F1 generation. The F1 generation contains 50% of the Ross parent hen CD lineage. Because the parental CD of broiler chickens abroad contains some recessive white feathers, 23-35% of the chickens with jute feathers will appear in the F1 generation; the genetics of black bone and black skin are relatively complicated, and 50-68% of the chickens are black bone and black. Skin; the black shank trait is inherited in a sex-linked recessive manner, so hens show black / blue shanks and roosters show white shanks. Individuals with black skin, black bones, and jute feathers were selected to remain in the F1 generation;

[0040] Step 2. Cross-cross fixation and multiplication of the male and female individual...

Abstract

The invention belongs to the technical field of poultry breeding. A method for breeding a new strain of black-bone chicken with higher production performance comprises the following steps of: step 1, taking parents of foreign broiler chicken as female parents instead of hen CD, and the black-bone chicken with jute feather inland as male parents, and generating a generation F1 through cross breeding, selecting and leaving individuals with jute feather, black bone, and black skin in the generation F1; step 2, crossing and propagating the female individuals and the male individuals obtained in the step 1, and separating out jute feather, recessive white feather, black feather, and reed catkins, and removing recessive white feather, from the colored feather colony through crossing, and purifying and fixing the hair color, black bone, black shin, sexual maturity and other appearance characters according to the family and individual selective method, improving the growing speed, reproductive performance and other economic characters; step 3, through the breeding of four or more generations, successfully breeding the new strain of the black-bone chicken with relatively higher production performance in jute feather, recessive white feather, black feather, and reed catkins. The method improves the early growing speed and egg laying performance of the black-bone chicken in the nation, and obviously reduces the feed / gain ratio.

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." [0003] Black-bone chicken has the characteristics of both medicine and food. According to modern medical research, black-bone chicken is rich in melanin, protein, B vitamins and other 18 kinds of amino acids and 18 kinds of trace elements. Among them, the content of niacin, vitamin E, phosphorus, iron, potassium and sodium is h...
