Embodiment 1

[0020] (1) Establish the basic group of Wuding chickens, select roosters with an adult weight of 3.5kg and hens with an annual egg production of 125 eggs for hybridization, and produce purebred Wuding roosters and large chickens with a weight of 3.5kg;

[0021] (2) Crossbreed the roosters selected in step (1) with hens of foreign egg-laying breeds to produce breeder chickens of the F1 generation. The F1 generation will be self-crossed to produce the F2 generation, and the annual egg production of the F2 generation hens will be 250. save seed;

[0022] (3) Crossbreed the roosters selected in step (1) with the hens in the F2 generation again, and fix the progeny male and female hens in cross-crossing to make them genetically stable, and then breed them into meat A new strain of chicken with both egg and egg types.

Embodiment 2

[0024] (1) Establish the basic group of Wuding chickens, select a rooster with an adult body weight of 3.6kg and a hen with an annual egg production of 125 pieces for hybridization, and produce purebred Wuding roosters and large chickens with a body weight of 3.5kg;

[0025] (2) Crossbreed the roosters selected in step (1) with hens of foreign egg-laying breeds to produce breeder chickens of the F1 generation. The F1 generation will be self-crossed to produce the F2 generation, and the annual egg production of the F2 generation hens will be 250. save seed;

[0026] (3) Crossbreed the roosters selected in step (1) with the hens in the F2 generation again, and fix the progeny male and female hens in cross-crossing to make them genetically stable, and then breed them into meat A new strain of chicken with both eggs and eggs, bred into a large chicken breed.

Embodiment 3

[0028] (1) Establish the basic group of Wuding chickens, select roosters with an adult body weight of 3.5kg and hens with an annual egg production of 135 pieces for hybridization, and produce purebred Wuding roosters and large-scale chickens with a weight of 3.5kg;

[0029] (2) Crossbreed the roosters selected in step (1) with hens of foreign egg-laying breeds to produce breeder chickens of the F1 generation. The F1 generation will be self-crossed to produce the F2 generation, and the annual egg production of the F2 generation hens will be 260. save seed;

[0030] (3) Crossbreed the roosters selected in step (1) with the hens in the F2 generation again, and fix the progeny male and female hens in cross-crossing to make them genetically stable, and then breed them into meat A new strain of chicken with both eggs and eggs, and the new breed of chicken is bred into a small chicken.

Abstract

The invention relates to the technical field of livestock and poultry breeding, in particular to a breeding method of a new variety of meat and egg dual-purpose chickens. The breeding method comprises steps as follows: a Wuding chicken underlying group is established, and large purebred Wuding cocks are reserved for reproduction; (2), the cocks selected in the step (1) and foreign hens for laying eggs are hybridized; (3), the chickens selected in the step (1) are hybridized with the hens in the step (2), descendant cocks and hens perform cross breeding, and the new variety of meat and egg dual-purpose chickens are bred. The chickens bred with the method have the characteristics of large size, strong bone, good fattening performance and fresh, tender and delicious meat and have excellent meat performance and egg laying performance and good production performance, and the egg shells are brown.

Description

technical field [0001] The invention relates to the technical field of livestock and poultry breeding, in particular to a method for cultivating a new strain of chicken with both meat and egg functions. Background technique [0002] With the development of high-efficiency animal husbandry, livestock and poultry with a single performance can no longer meet the rapid consumption demand, such as dairy cows. During the breeding process, breeders hope that the milk production of dairy cows is large and of good quality, and they also hope that dairy cows have excellent milk production Meat performance; the same is true for poultry, that is, it is expected to produce more eggs and better meat performance. The development of high-quality chickens with both eggs and meat has higher economic benefits. [0003] Wuding chicken is a meat-type variety, known for its large body, tender and delicious meat, known as "Wuding Strong Chicken", mainly produced in Wuding and Luquan Yi and Miao Au...
