A method for producing a high-yield green-shell egg chicken mating line with differentiating male and female feathers and application thereof

By breeding a breeding line of green-shelled laying hens with speckled feathers, and using molecular identification and disease eradication methods, the problem of low egg production performance of Wenshang speckled feather chickens has been solved, resulting in a significant improvement in eggshell brightness for high-yielding green-shelled laying hens, thus meeting market demand.

Abstract

The present application relates to the technical field of poultry genetics and breeding, and particularly relates to a method for breeding a high-yield green-shell egg chicken with plumage speed self-distinguishing male and female and application. The method for breeding is to crossbreed plumage high-yield green-shell egg chickens with plumage speed self-distinguishing male and female, in which the male chickens are plumage high-yield green-shell fast plumage chickens and the female chickens are plumage high-yield light-powder-shell slow plumage chickens. The plumage high-yield green-shell egg chickens are bred by plumage speed self-distinguishing, in which the male chickens are slow plumage and the female chickens are fast plumage, and the male and female chickens are plumage high-yield green-shell egg chickens. By introducing the bloodline of high-yield white-shell egg chickens, the production performance and eggshell brightness are significantly improved under the premise of keeping the female chickens of the commercial generation producing green-shell eggs, and the market advantage is significantly improved.
