Problems solved by technology

[0006] Local chicken breeds in my country include egg type, meat type and dual-purpose type. Among them, the meat-use type and dual-purpose type often have the advantage of good meat quality, but at the same time have the disadvantages of slow growth and long feeding cycle

Embodiment 1

[0025] Embodiment 1, cultivating green foot dwarf small recessive white feather broiler chicken

[0026] The green-footed dwarf recessive white-feathered broiler chickens bred in this embodiment are genotype Z iddw / Z iddw ; cc rooster, or genotype Z iddw / W; cc recessive homozygous hens. Its parent is genotype Z idDw / Z idDw ; CC's Shouguang chicken rooster (purchased from Cilun Breeder Farm, Shouguang City, Shandong Province) and genotype Z Iddw / W; cc star C line hen (purchased from French star broiler company).

[0027] 1. The specific method is as follows:

[0028]

[0029]

[0030] (1) Set 15 genotypes as Z idDw / Z idDw ; CC's Shouguang chicken rooster (phenotype is green feet and black feathers non-dwarf) and 105 genotypes are Z Iddw / W; cc's star C line hen (phenotype is short body with yellow shanks and white feathers) was mated, and 17 genotypes were obtained. Iddw / Z idDw ; Cc's F1 generation rooster.

[0031] The 15 genotypes are Z idDw / Z idDw ; ...

Embodiment 2

[0037] Example 2. Breeding the green-legged dwarf recessive white-feathered broiler chickens bred in this example, the genotype is Z iddw / Z iddw ; cc recessive homozygous rooster, or genotype Z iddw / W; cc recessive homozygous hens. Its parent is genotype Z idDw / W; CC's Shouguang chicken hen (purchased from Cilun Breeder Farm, Shouguang City, Shandong Province) and genotype Z Iddw / Z Iddw ; cc star C rooster (purchased from French star broiler company). Genotype is Z idDw / W; The phenotype of CC's Shouguang chicken hen is green feet and non-dwarf black feathers. Genotype is Z Iddw / Z Iddw ; The phenotype of the cc star C line rooster is yellow feet and short white feathers.

[0038] 1. The specific method is as follows:

[0039] (1) Set 105 genotypes as Z idDw / W; CC's Shouguang chicken hen and 15 genotype Z Iddw / Z Iddw ; cc's star C roosters were mated, and 18 genotype Z were obtained Iddw / Z idDw ; Cc's F1 generation rooster.

[0040] The 15 genotypes are ...

Abstract

The invention discloses a method for culturing green-foot short and small recessive white feather egg chickens. The method comprises the following steps of: hybridizing star C series chickens and Shouguang chickens to generate a generation F1; and hybridizing recessive homozygous cocks with genotype Ziddw / Ziddw; CC obtained by culturing the generation F1 and / or recessive homozygous hens with genotype Ziddw / W; cc to obtain the green-foot short and small recessive white feather egg chickens. The hybridization mode comprises that the star C series cocks with genotype ZIddw / ZIddw; cc are hybridized with the Shouguang hens with genotype ZidDw / W; CC, or the star C series hens with genotype ZIddw / W; cc are hybridized with the Shouguang cocks with genotype ZidDw / ZidDw; CC. By fully using the advantage of sex-linkage recessive short and small genes in the green-foot short and small recessive white feather egg chickens, the consumption of feed is reduced, the raising space is saved, and the conversion rate of the feed is improved. Meanwhile, when the green-foot short and small recessive white feather egg chickens are mated with the green-foot chickens, green-foot characteristic and parent matched feather characteristic are reserved in the descendants, and appearance characteristics of the population favored by regional markets are kept.

Description

technical field [0001] The invention relates to a method for cultivating a new breed (line) of chicken, in particular to a method for cultivating a green-legged dwarf recessive white-feathered broiler chicken. Background technique [0002] There are many varieties of local chickens in China. There are 27 local varieties of chicken listed in "China Poultry Variety Resources Chronicle", of which 13 varieties have the characteristics of green feet. Shouguang chicken, originally produced in the Cijia and Lunjia areas of the paddy field area in Shouguang, Shandong, is also known as "Cilun chicken". It is characterized by strong disease resistance, resistance to rough feeding, good feeding, big body, high feet, strong bones, gray-black beak, shins and toes, and fair skin; its meat is tender, delicious, and the soup is mellow. Excellent nutrition. After testing, the black color of its shanks is controlled by the recessive gene id, which is located on the Z chromosome. [0003] T...
