Embodiment 1

[0008] The cultivation and production method of dwarf green-shell layer hens in this embodiment is carried out according to the following steps: (1) select the cock ZdwZdw containing the dwarf gene to breed with the hen ZDWW in the green-shell layer breed, and produce the F1 generation; (2) F1 Select the hen ZdwW individual with the dwarf gene characteristic in the generation; (3) use the hen ZdwW individual with the dwarf gene characteristic selected from step (2) to mate with the cock ZdwZdw containing the dwarf gene again to produce the F2 generation; (4 ) There are individuals with dwarf gene characteristics in the F2 male and female hens, and these male and female hens with dwarf gene characteristics are selected and retained : ZdwZdw; ♀: ZdwW; (5) The male and female hens with dwarf gene characteristics in step (4) were cross-fixed, and through family selection and individual selection, testcross detection, green-shell layer hens with dwarf characteristics were bred Pur...

Embodiment 2

[0021] The cultivation and production method of the dwarf green-shell hens in this embodiment is carried out according to the following steps: (1) select the hen ZdwW containing the dwarf gene to breed with the cock ZDWZDW of the green-shell hen breed, and produce the F1 generation; (2) in the F1 Select and retain the cock ZdwZDW individual with the dwarf gene feature in the generation; (3) use the cock ZdwZDW individual with the dwarf gene feature selected from step (2) to mate with the hen ZdwW containing the dwarf gene again to produce the F2 generation; (4) There are individuals with dwarf gene characteristics in the F2 male and female hens, and these male and female hens with dwarf gene characteristics are selected and retained : ZdwZdw; ♀: ZdwW; (5) The male and female hens with dwarf gene characteristics in step (4) were cross-fixed, and through family selection and individual selection, testcross detection, green-shell layer hens with dwarf characteristics were bred P...

Embodiment 3

[0034] The cultivation and production method of the dwarf green-shell hens in this embodiment is carried out according to the following steps: (1) Select the hen ZdwW containing the dwarf gene to mate with the rooster ZDWZDW in the green-shell breed, and the cock ZdwZdw containing the dwarf gene and the green-shell hen are mated. In laying hen breeds, hen ZDWW is bred to produce F1 generations respectively, namely F1a and F1b; (2) select and retain cock ZdwZDW individuals and hen ZdwW with dwarf gene characteristics in the F1 generation; (3) select from step (2) The remaining rooster ZdwZDW individuals with dwarf gene characteristics are mated with the hen ZdwW containing dwarf gene characteristics to produce F2 generation; (4) There are individuals with dwarf gene characteristics in both F2 male and female chickens, and these individuals with dwarf gene characteristics are selected and kept Male and female hens; (5) cross-fixing the male and female hens with dwarf gene charact...

Abstract

The medicine for cultivating and producing dwarf green shell egg layer includes the following steps: mating cock or hem with dwarf gene with hem or cock of green shell egg chicken to generate the F1 generation; selecting hems or cocks with dwarf gene characteristic from the F1 generation; re-selecting hems or cocks with dwarf gene characteristic to generate the F2 generation; selecting and leaving hems and cocks individuals with dwarf gene characteristic from the F2 generation; and genealogy selecting and breeding, individual selection, test crossing and detection. The present invention introduces dwarf gene into green shell egg chicken variety, and can utilize dwarf gene fully and protect green shell egg chicken variety resource.

Description

technical field [0001] The invention relates to a method for cultivating and producing chickens, in particular to a method for cultivating and producing dwarf green-shell hens. Background technique [0002] There are many varieties of local chickens in my country, and there are 27 varieties of chickens listed in the "Resources of Poultry Breeds in China". Green-shell laying hens have strong disease resistance, resistance to rough feeding, and easy feeding. Their meat is tender, delicious, and the soup is mellow. It is a good nutrition. The eggs of green-shell hens contain a large amount of lecithin, vitamins, amino acids, and the content of trace elements such as selenium, iodine, iron, and zinc is 5-10 times higher than that of ordinary eggs. After testing, the green shell egg gene is a dominant genetic gene. The sex-linked dwarf gene dw is a recessive sex-linked genetic gene located on the Z chromosome. The dw gene has a significant impact on the growth and body shape de...
