A kind of breeding method of male and female pigeons with long and short cashmere

Abstract

The invention relates to a method for breeding pigeons, in particular to a method for breeding male and female pigeons with long and short cashmere, and belongs to the field of biotechnology. The invention discloses a method for breeding pigeons that can be separated from male and female. It includes identifying the genotype of the natal-down gene locus on the Z chromosome of the breeding pigeon that controls the long and short down traits of young down feathers, and breeding long-down pure lines and short-down pure lines. The male and female pigeons of different genotypes are used as the male and female parents to crossbreed according to a certain combination to produce a commercial generation. The commercial generation can be based on the long-down and short-down phenotypes of the young pigeons in the first 5 days after hatching to identify males and females. The method provided by the present invention greatly reduces the cost of early gender identification in the process of breeding traditional pigeon commercial generations. At the same time, compared with the existing feather color self-identification method, the method is not restricted by the strict matching of the feather color of the parents, and adapts to The range is wider, and the breeding material can be selected more flexibly to cultivate pigeon matching lines, which has important breeding value and economic value.

Description

technical field [0001] The invention relates to a method for cultivating pigeons, in particular to a method for cultivating long-short-velvet pigeons from male and female pigeons, belonging to the field of biotechnology. Background technique [0002] Pigeons are the fourth largest poultry in my country after chickens, ducks and geese. By 2021, the number of pigeons in the country has exceeded 80 million pairs. At present, the main feather color strains in the production of egg pigeons in my country are American king pigeon, Kanu pigeon, Texon pigeon, Texen hybrid derivative varieties, etc. Among them, white-feathered pigeons such as white-feather king pigeon and white Kanu pigeon have better egg-laying performance. It is the main species cultivated in my country. At present, one of the bottlenecks restricting the development of my country's pigeon industry is the early sex identification of pigeons. As a late adult bird, the pigeon weighs about 20g after hatching, and its p...

Problems solved by technology

However, the Teikesen pigeon strain has a large body size and average egg production performance, so it is not suitable as a breeding material for small grain-saving egg pigeons. In addition, the feather color of this strain has strict requirements on the matching method of the parent generation's feather color. Compared with other breeds When crossbreeding, the success rate of self-separation will be reduced, especially when using Texen pigeons to breed egg pigeons, because the genetic background of white feather color is very complicated, and its genetic law is not clear at present, so it cannot be introduced into the current market. The high-yield white feather breeds are crossed with it, otherwise it will destroy the original feather color self-identification mode of Texen pigeons, resulting in the inability of the offspring to distinguish between male and female
