Seed production method of feather color dual auto-sexing black feather and pink shell high-yield special laying hen complete set line

Abstract

The invention relates to the technical field of poultry genetic breeding, in particular to a seed production method of a feather color dual auto-sexing black feather and pink shell high-yield speciallaying hen complete set line. According to the seed production method, Luhua fast-feathering hens and matched adult slow-feathering cocks are hybridized and matched. Black feather chickens and Luhua feather chickens are bred at the same time through feather color dual auto-sexing, feather color dual auto-sexing can be achieved in parental generations and commercial generations, compared with existing black feather laying hens, feather speed identification is adopted, more time and labor are saved, male and female can be identified only by seeing feather colors from the outside, breeding of special laying hens of obvious local varieties is achieved, and the market advantage is remarkable.

Description

technical field [0001] The invention relates to the technical field of poultry genetics and breeding, in particular to a seed production method of a matching line of laying hens with double feather color, self-separated male and female, black feather powder shell and high-yield characteristics. Background technique [0002] With the development of the chicken industry and the intensification of market competition, people's demand for male and female identification is becoming more and more urgent to reduce feeding costs. Male and female identification can be carried out by two methods: anal identification method and feather speed or feather color self-sexing method. The anus identification method has high requirements on the identification personnel, and the labor intensity is high. The identification rate also varies greatly due to different identification personnel, and improper operation is easy to cause harm to the chickens. Feather speed or feather color has obvious ge...

AI Technical Summary

Problems solved by technology

The breeding mode of Xinyang black-feathered laying hens, which uses feather speed and self-separation of sexes, has a low identification rate and is time-consuming and labor-intensive in the research and production of existing chicken breeds.

[0004] At present, the requirements for the size and appearance of chickens in the market are getting higher and higher, and black-feathered and reed-feather chickens are particularly favored by consumers. To obtain reed-feather and black-feather laying hens, different breeds and different matching combinations are usually used to breed them separately. There is no breeding mode that can obtain two kinds of laying hens at the same time and achieve faster and more convenient feather color self-sexing and high egg production
