Autosexing mating method for high-yield laying pigeons

Abstract

The invention discloses an autosexing mating method for high-yield laying pigeons. The method includes the steps that male pigeon and female pigeon parents different in color are hybridized to obtain the F1 generation, and male and female of the F1 generation are confirmed with color. Existing domestic and overseas pigeon varieties are used as materials, part of strains are selected for mating hybridization, the purpose of autosexing in the first generation of hybrid is achieved, eleven autosexing mating methods are created, and the autosexing accuracy reaches 100%. Autosexing can be achieved before young pigeons grow to sale age in days, female pigeons obtained after distinguishing are directly used for laying eggs, when growing to the sale age in days, male pigeons are sold as meat pigeons, the male and female distinguishing measure can be simplified, cost of male pigeon raising in the early stage is saved, the management efficiency is improved, the blank of an autosexing mating strain of the laying pigeons in China is filled up, domestic and overseas pigeon genetic resources are fully used, and huge economic and social value is created for laying pigeon production in China.

Description

technical field [0001] The invention relates to the technical field of laying pigeon breeding, in particular to a matching method for self-separating male and female of high-yield laying pigeons. Background technique [0002] At present, the main feather color strains in the production of egg pigeons in my country include white feather king pigeons, white Kanu pigeons, and Texen pigeons (also known as Taishen pigeons and Taiping pigeons). Among them, the production performance (egg production rate) of white king pigeon and white Kanu pigeon is relatively high, but the offspring cannot be separated from male and female. The process is cumbersome, and the identification cost is relatively expensive; Texen pigeon is currently the only new strain of pigeon in my country that can be separated from male and female. However, the production performance (egg production rate) of this strain is low, and the disease resistance is weak. The size of the strain is too large, and the cost of...

Problems solved by technology

Among them, the production performance (egg production rate) of white king pigeon and white Kanu pigeon is relatively high, but the offspring cannot be separated from male and female. The process is cumbersome, and the identification cost is relatively expensive; Texen pigeon is currently the only new strain of pigeon in my country that can be separated from male and female. However, the production performance (egg production rate) of this strain is low, and the disease resistance is weak. The size of the strain is too large, and the cost of feed is high

At present, some pigeon breeding companies can only identify male and female pigeons based on experience when breeding white-feathered egg pigeons, and the identification rate is low. , behavior and other appearance reactions to eliminate some cocks in the group, and finally use the remaining group (there are different proportions of cocks in the remaining group) as egg pigeons; or use molecular biology methods to identify the sexes of the reserved breeding pigeons Eliminate cocks, but doing so wastes a lot of feed or manpower

There are also some pigeon breeding companies that directly use Taishen pigeons as egg pigeon strains, but the mortality rate of reserved breeding pigeons is relatively high, and the egg production rate after adulthood is low
