Embodiment

[0031] Such as Figure 1-3 As shown, the method of producing high-yielded reed feather green shell density, including the following operation steps:

[0032] S1: Using the high-yield egg chicken, No. 1, the Chicken A-strait cock and hen are Zeng Zu Dynasty. At the beginning of the bullion 1 day, the individual is used for the cultivation of the first Father A, and eliminated by transverse assay. Hybrid gene, select genotype ♂Z Kb Z Kb Oo, ♀Z Kb WOO is hybridized, and eliminated weak bulls, using individual cage, labor-saving, 500 deposits in each generation, proportion of male muna 1:10; finally selected homozygous genotype Census Kb Z Kb OO to form the first parent A;

[0033] Using high-yield egg chicken, No.1, No. 1, Eggs, B-B-Bian cock, and hen to Zeng Zu Dynasty. At the beginning of the bullion 1 day, the individual is used for the purpose of the first mother series B, and the means of transverse assays are eliminated. Gene, select genotypes for ♂Z Kb Z Kb OO and ♀Z Kb WOO is ...

experiment example

[0041] 1. Comparison of the production performance of parents in the parent, see Table 1:

[0042] Experimental Group: High-yielded reeds of the male shells of the female egg chicken. Parents of the egg chicken. Parents: Purebred Wen rush parents.

[0043] Table 1 Production performance of parental seed chicken cultivated by the present invention

[0044]

[0045]

[0046] As can be seen from Table 1, the production of parental seed chickens of the present invention is higher, and the maid is more than 120-week old output, and the number of eggs in 72 weeks is increased. The amount increased by more than 60%, the breeding cost is significantly reduced; the parent's hen is the father of the father of the high-grade egg chicken, and the color is a hidden golden feather, so the descendants of the reed feathers are hybridized. For Luhufu, and its production performance is comparable to high yaw egg chickens (300 eggs from 72 weeks old), which can be seen that the parent of this ge...

Abstract

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. The seed production method of the self-separated high-yielding reed-flower feather green-shell laying hen uses the non-reed flower feather high-yield layer A line and the non-reed flower feather high-yield layer B line to form the first male line A and the first female line B; the first After pure breeding of the male line A and the first female line B, the high-yielding, slow-feather, non-reed feathers, and non-green shell hens were selected as the second female line AB; the fast-feather, non-green shell cocks were selected as the male parent of the reed chicken strain. Select fast-feather and green-shell hens from the non-reed chicken strains as the female parent, and after the two are crossed for pure breeding, the fast-feather, reed flower feathers, and green-shell genes are selected to be homozygous for the terminal male line C; the terminal male line C and the second female line AB The commercial generation is obtained by hybridization, the slow feather is a rooster, and the fast feather is a hen. The high-yielding reed flower feather green-shell laying hens obtained by adopting the seed production method have the advantages of high yield, self-separation of sexes, and green eggshells.

Description

Technical field [0001] The present invention belongs to the technical field of poultry genetic breeding, and in particular, the method of producing high-yielded reed feathers with self-producing reeds. Background technique [0002] my country is broad, the local variety has a rich resources, and different geographies have formed varieties with local characteristics, and the characteristic traits are highlighted. Wen Shangluhua chicken has a beautiful appearance, delicious meat, rich in egg, but its output is low. The green shell egg color is bright, and it is very popular among consumers, so the market price is high, but there is also a shortcomibility of low egg loss. The green shell egg this quality is a common-stained dominant gene control. Therefore, if you can introduce the green shell egg gene into the cloves, the green shell new product, which has the appearance of the upper contulstrous chicken, and has high yield. Variety hybridization, improving the production of eggs i...
