Breeding method for complete set of male parents with yellow-feather black-neck laying chickens and mode for production of hybrid seeds

Abstract

The invention relates to the technical field of a breeding industry, in particular to poultry breeding technology. The invention concretely relates to a breeding method for a complete set of male parents with yellow-feather black-neck laying chickens and a mode for production of hybrid seeds. The breeding method for a complete set of male parents comprises following steps: utilizing high-yield rhode island red chickens to crossly breed with yellow-feather black-neck chickens selected by a market demand for production of a synthetic line and selecting chickens needed by the market after cross breeding of the synthetic line to continuously breed to be a first generation of chickens; screening and breeding the first generation of chickens to obtain a second generation of chickens; obtaining a third generation of chickens after screening and breeding the second generation of chickens; specifically screening before reserving seeds for all generations of groups and screening breeding chickens in the third generation of chickens as the complete set of male parents with yellow-feather black-neck laying chickens; utilizing rhode island white chickens as female parents to form a high-yield complete set of yellow-feather black-neck chickens, wherein female chicks of descendants of parent generations are yellow-feather black-neck and male chicks are white-feather; and female and male chicks can be distributed. The egg-producing amount of products aged the 72 week is more than 300.

Description

technical field [0001] The invention belongs to the technical field of breeding industry and relates to poultry breeding technology, in particular to a method for breeding male parents of a matching line of yellow-feathered and black-legged laying hens and a seed production model of the matching line. Background technique [0002] The main difference between yellow-feathered black-legged chickens, hemp-feathered black-legged chickens and black-feathered black-legged chickens is the proportion of black feathers to the total body feathers of chickens. More than 95% of the feathers are all yellow feathers and black legs are yellow feathers and black legs. Yellow feathers have dark yellow or light yellow feathers and only have black feathers on the tail or neck. There are many local chicken breeds in my country that are yellow-feathered and black-legged chickens, such as Gushi chicken and Huainan chicken, etc. There is no matching line of layer hens with yellow feathers and blac...

Problems solved by technology

[0003] Local chicken breeds in my country are beautiful in appearance and delicious in chicken and eggs, but the egg production rate is low. The annual egg production is less than 200. It is difficult to purify Salmonella pullorum and avian lymphoid leukemia virus, and the positive rate is generally higher than 10%.
