Embodiment 1

[0018] In the present embodiment, the white-feather bantam laying hen cultivation production method is carried out according to the following steps: (1) use recessive white-feather hen ccZ Dw W and Bantam CCZ dw Z dw Mating production F 1 (2) select and retain male and female hens carrying recessive white feather and dwarf genes ( CZ dw w,♀CcZ Dw Z dw ); (3) produce F from mating male and female chickens in step (2) 2 generation; (4) from F 2 Recessive white-feathered bantam rooster (ccZ dw Z dw ) and recessive white bantam hen (ccZ dw W); (5) utilize the recessive white-feathered bantam male and hen in step (4) to form a family, through family selection and individual selection, breed and expand the group, and cultivate the white-feathered bantam germplasm with recessive white feather characteristics resource. (6) Use the germplasm resources to breed specialized laying hen male lines and local native chicken female lines or to cultivate specialized broiler female ...

Embodiment 2

[0035] In the present embodiment, the white-feathered bantam laying hen cultivation production method is carried out according to the following steps: (1) use recessive white-feathered hen (ccZ Dw W) and Bantam (CcZ dw Z dw ) mating to produce F 1 (2) Male and female hens carrying recessive white feather and dwarf genes (♂CcZ Dw Z dw , ccZ Dw Z dw ;♀CcZ dw W, ccZ dw W); (3) produce F from mating male and female chickens in step (2) 2 generation; (4) from F 2 Recessive white-feathered bantam rooster (ccZ dw Z dw ) and recessive white bantam hen (ccZ dw W); (5) the recessive white-feathered bantam male and hen in step (4) is formed into a family, and through family selection and individual selection, breeding and expanding the group, and cultivating the white-feather bantam germplasm with recessive white feather characteristics resource. (6) Use the germplasm resources to breed specialized laying hen male lines and local native chicken female lines or to cultivate s...

Embodiment 3

[0054] In the present embodiment, the white-feathered bantam laying hen cultivation production method is carried out according to the following steps: (1) use recessive white-feathered cock (ccZ Dw Z dw ) and bantam hen (CCZ dw W) Mating produces F 1 generation; (2) from F 1 Males carrying the recessive white feather gene (CcZ dw Z dw , Cc Z Dw Z dw ) and bantam hen (CcZ dw W); (3) use from F 1 F 2 generation; (4) from F 2 Recessive white-feathered bantam rooster (ccZ dw Z dw ) and recessive white bantam hen (ccZ dw W); (5) the recessive white-feathered bantam male and hen in step (4) is formed into a family, and through family selection and individual selection, breeding and expanding the group, and cultivating the white-feather bantam germplasm with recessive white feather characteristics resource. (6) Use the germplasm resources to breed specialized laying hen male lines and local native chicken female lines or to cultivate specialized broiler female lines and...

Abstract

A breeding method of recessive white feather bantam germ plasm resource includes: mating a recessive white hen and a mini type cock to produce F1 generation; selecting and mating a hen and a cock which carry recessive white feather gene and mini gene from the F1 generation to produce F2 generation of chicken; and selecting a recessive white feather bantam cock and a recessive white feather bantam hen from the F2 generation to set up a family; or includes: mating a recessive white cock and a mini type hen to produce F1 generation; selecting and mating a cock carrying recessive white gene and a mini type hen from the F1 generation to produce F2 generation; and selecting a recessive white feather bantam cock and a recessive white feather bantam hen from the F2 generation to set up a family. Through family selection and individual selection, the productivity is improved and bantam germ plasm resource with the feature of recessive white feather is bred through propagation and group expanding. The recessive white feather bantam germ plasm resource can be used for breeding high-qaulity laying hens and / or high-quality poulards and producing mini type high-quality indigenous laying hens commodity generation or normal body type high-quality poulards commodity generation.

Description

technical field [0001] The invention relates to a method for cultivating chicken germplasm resources and the supporting application of the breeder chicken, in particular to a method for cultivating recessive white-feathered bantam and the supporting application. It belongs to the field of breeding technology. Background technique [0002] my country's chicken and egg production has gradually reached a balance between supply and demand, and is changing from quantity to quality. The market share of early imported white-feathered broilers and white-shell and brown-shell laying hens is gradually decreasing due to the influence of consumers' dietary preferences and cultural habits. The production and consumption of local high-quality broiler chickens and laying hens are growing rapidly. In recent years, the development speed has reached more than 15%. It is a rare industry in the entire animal husbandry industry that is still growing rapidly and has become a major feature of chick...
