Embodiment Construction

[0016] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 A kind of seed production method that can make the plumage color of one-day-old chicks accurately from different males and females shown, this method comprises the following steps:

[0018] 1) The pure golden Colombian cock iiCoCoss was crossed with the standard breed White Rock IIcocoSW to obtain the F1 pure white cock IiCocoSs;

[0019] 2) F1 white-feathered cock IiCocoSs was backcrossed to yellow-feathered male hen iiCoCosW, and white-feathered black-tailed cock iiCo-Ss and white-feathered black-tailed hen iiCo-SW were selected, where: - represents Co or co;

[0020] 3) White-feathered black-tailed rooster iiCo-Ss and white-feathered black-tailed hen iiCo-SW are self-propagating, identified according to tail feathers, main wing feathers, and sickle feathers, the hen with white feathers and black tails, the genotype is iiCoCo...

Abstract

The invention relates to a chicken breeding method, in particular to a breeding method capable of realizing feather color-based accurate self identification of the sex of a one-day chicken, which comprises the following steps: 1) crossing a pure golden Colombian feather cock with a white plymouth rock of a standard variety to obtain an F1 pure white feather cock; 2) back crossing the F1 pure white feather cock with a hen having a yellow feather male parent, and selecting a white-feather and black-tail cock and a white-feature and black-tail hen; 3) allowing a silvery-feather and black-tail cock and a white-feather and black-hen to propagate by themselves, selecting a silvery-feather and black-tail hen, eliminating golden-feature individuals, selecting a male typical Colombian feather individual, performing test cross of the male typical Colombian feather individual and the silvery-feather and black-tail hen, and eliminating heterozygous male non-silvery typical Colombian feather individuals from the offspring; and 4) crossing the silvery-feather and black-tail hen with a red-feather paternal line or yellow-feather paternal line having a golden-feather gene, wherein among the bred one-day chickens, those with white feathers are cock and those with golden feather are hens, and the self identification rate is 100 percent.

Description

technical field [0001] The invention relates to a chicken breeding method, in particular to a seed production method capable of making the feather color of one-day-old chicks accurate from male to female. Background technique [0002] Since laying hens and broilers have entered into large-scale and specialized production, both laying hens and breeders are required to identify male and female at one day old to reduce future feeding costs. There are two common methods of male and female identification, one is the anal identification method, and the other is the identification by feather speed or feather color. The anus identification method not only requires the identification personnel to carry out long-term professional training, but also has high labor intensity, the identification rate varies from person to person, and improper operation is easy to injure chickens. Male and female one-day-old chicks have different feather color and feather speed. Among them, the simplest ...
