Breeding method of black feather quail strain for eggs

Abstract

The invention discloses a method for cultivating black-feathered quail strains for eggs. Using the black-feathered feather color mutants naturally occurring in Korean quail hybrid populations for eggs as materials, the genes of strains such as Korean quail and Beijing white-feathered quail are introduced into the breeding method. The black-feathered quail strain is used for eggs, and the cultivation method of the present invention is short in time and fast in speed. The strain bred by the breeding method of the present invention maintains the advantages of high egg production, strong disease resistance, and easy management of Korean quail for eggs, and overcomes the shortcomings of Beijing white-feathered quail such as shyness and weak early viability, and has the same advantages as other feather-colored quails. Different plumage characteristics. Not only that, black-feathered quail can also be used to form a self-sex matching line with Beijing white-feathered quail and yellow-feathered quail. Once the quail comes out of the shell, the male and female can be identified by feather color. The identified female quail can be directly used for laying eggs, and the male quail It can be eliminated early or can be intensively fattened and sold as meat quail. This is of great significance for simplifying the identification of male and female, saving the cost of raising male quail in the early stage, and improving management efficiency.

Description

technical field [0001] The invention relates to a method for cultivating quail strains for eggs, and relates to the technical field of quail breeding. Background technique [0002] The main egg product lines in my country's quail production are Korean quail, Beijing white-feather quail and yellow-feather quail and their self-separated male and female matching lines. Among them, Korean quail is the main breed of quail for eggs in my country, and Beijing white-feather quail and yellow-feather quail are both It is the result of recessive mutations at the albino locus (B / b) and yellow feather locus (Y / y) on the Z chromosome of Korean quail. [0003] The current problem is that most quail farms and professional households have self-propagated and self-raised for many years, lack of systematic breeding of varieties, serious inbreeding and degeneration of varieties, and many production groups have reduced adaptability and production performance.
