Embodiment

[0031] Such as Figure 1-3 As shown, the seed production method of the high-yield type Luhuayu green-shell laying hens of this self-separated male and female comprises the following steps:

[0032] S1: Using the high-yielding layer hen Jinghong No. 1 layer A line roosters and hens as great-grandparents, select slow-feathered individuals at the age of 1 day after hatching for the cultivation of the first male line A, and eliminate them by means of cross-crossing measurement and other means Heterozygous gene, select genotype ♂Z Kb Z Kb oo,♀Z Kb Woo conducts crossbreeding, eliminates weak chicks, adopts individual cage breeding, and artificial insemination. The number of seeds in each generation is more than 500, and the ratio of male to female is 1:10; the homozygous genotype rooster Z is finally selected. Kb Z Kb oo, form the first paternal line A;

[0033] Using the high-yield laying hen Jinghong No. 1 laying hen B line roosters and hens as great-grandfathers, the slow-fe...

experiment example

[0041] 1. The production performance comparison of parent generation breeders, see Table 1:

[0042] Experimental group: self-separated high-yield parent breeders of Luhuayu green-shell layer hens; control group: purebred Wenshang Luhua parent breeders.

[0043] Table 1 The present invention's cultivated parent generation breeder production performance

[0044]

[0045]

[0046] As can be seen from Table 1, the production performance of the parent breeder chickens of the present invention is higher than using the purebred Wenshang Luhua chicken as the female parent, and the number of eggs laid at the age of 72 weeks is improved by more than 120, which is higher than that of the Wenshang Luhua chicken. The yield increased by more than 60%, and the cost of seed production was significantly reduced; the parental hen is a paternal hen in the process of producing high-yield laying hens, and the feather color is recessive golden feather, so the feather color of the offspring a...

Abstract

The invention belongs to the technical field of poultry genetic breeding, and in particular to a method for seed production of automatic sexing high-yield type Luhua feather green shell laying hens. The method for seed production of the automatic sexing high-yield type Luhua feather green shell laying hens adopts non-Luhua feather high-yield laying hens A and non-Luhua feather high-yield laying hens B to form a first paternal line A and a first maternal line B; high-yield, slow feather, non-Luhua feather and non-green shell hens are remainedas a second maternal line A B after the first paternal line A and the first maternal line B are hybridized for pure breeding; fast feather and non-green shell cocks are selected from Luhua chicken varieties and used as male parents, fast feather and green shell hens are selected from non-Luhua chicken varieties and used as female parents, the male parents and the female parents are hybridized for the pure breeding, the fast feather, Luhua feather and green shell gene isozygoty are selected as a final paternal line C; the final paternal line C and the second maternal line A B are hybridized to obtain a commercial generation, wherein the slow feather is a cock and the fast feather is a hen. The automatic sexing high-yield type Luhua feather green shell laying hens obtained from the seed production method has the advantages of high yield, automatic sexing and green eggshells.

Description

technical field [0001] The invention belongs to the technical field of poultry genetics and breeding, and in particular relates to a seed production method of high-yielding reed-feather green-shell laying hens. Background technique [0002] my country has a vast territory and rich resources of local varieties, and varieties with local characteristics have been formed in different regions, with outstanding characteristic traits. Wenshang reed chicken has the advantages of beautiful appearance, delicious meat, and rich egg nutrition, but its output is low. Green-shell eggs are bright in color and are deeply loved by consumers. Therefore, the market price is relatively high, but there are also disadvantages of low egg production. The quality trait of green-shelled eggs is controlled by an autosomal dominant gene. Therefore, if the gene for green-shelled eggs can be introduced into Wenshang reed chicken, a new green-shelled strain with the body and appearance characteristics of...
