Description
Technical field
The present invention relates to a kind of chicken breeding method, particularly relate to a kind of Japanese instar chickling plumage look that can make accurately from the producing method for seed of other male and female.
Background technology
Since laying hen and meat chicken enter scale and Virtual production, laying hen and kind chicken all require to differentiate male and female when an age in days, to alleviate feeding cost in the future.Current male and female discrimination method has two kinds, and one is anal identification method, and two is utilize plumage speed or plumage look from other.Anal identification method not only requires that discriminating personnel carry out long-term professional training, and labour intensity is large, resolution has varied with each individual, and height has low, and misoperation easily hinders chicken.One Japanese instar chickling male and female is divided from other from not having plumage look and plumage speed, wherein the most simply, be utilize sex-linked golden feather genes (s) silver color feather genes (S) to carry out plumage look from other the most fast, wherein s and S is allelomorph, silver color plumage is dominant relative to golden plumage, but and not exclusively.As shown in Figure 1, its general principle and flow process as follows:
First set up respectively two strains being with isozygoty golden plumage and the silver color plumage that isozygotys, and do with silver color plumage system maternal, golden plumage system makes male parent, and in one age in days offspring, white person is public young bird, and golden person is female young.
Research shows; because silver color plumage is incomplete dominance to golden plumage; so when lacking modifier gene; utilize the male and female of gold and silver look feather genes from rate is not high; usually can only reach between 90-95%; even lower (Kang Xiangtao etc. 1995, peaceful China 2008), cannot reach the effect that scale utilizes.
Applicant has applied for that (application number: 201010183909.7 applyings date: 2010-05-27) discloses a kind of Japanese instar chickling plumage look that can make accurately from the producing method for seed of other male and female; the method comprises the following steps: 1) proof gold look Colombia plumage cock and standard variety White Rock hybridize, and hybridizes to obtain F1 pure white feather cock; 2) F1 pure white feather cock backcrosses to yellow plumage this hen public, and select and remain white plumage black tail cock and Bai Yu black tail hen; 3) silvery white plumage black tail cock and Bai Yu black tail hen are from numerous, and hen stays silvery white plumage black tail person, eliminate golden plumage individual; Cock stays typical Colombia plumage type individual, and carries out being measured with silvery white plumage black tail hen, eliminates the heterozygosis cock occurring non-silvery white typical case Colombia plumage type individuality in offspring.4) silvery white plumage black tail hen and red Yufu system or the mating of yellow Yufu system of being with golden feather genes, the Japanese instar chickling produced, white plumage type is cock, and golden yellow plumage is hen; 100% is reached from not other rate.But there is a difficult problem in this patent, in step 3), cock stays typical Colombia plumage type individual, genotype is iiCoCoSS or iiCoCoSs, and carry out being that iiCoCoSW hen is measured with genotype, eliminate individual iiCoCoSs and iiCocoSS of heterozygosis cock occurring non-silvery white typical case Colombia plumage type individuality in offspring, be difficult to obtain the individual iiCocoSS of heterozygosis cock.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of Japanese instar chickling plumage look that can make accurately from the producing method for seed of other male and female, the Japanese instar chickling that the method is produced, all can plumage look from other male and female, and all reach 100% from not other rate.
