Sex self-distinguishing supporting method for high-yield layer pigeons

Abstract

The invention discloses a sex self-distinguishing supporting method for high-yield layer pigeons; male and female parents of male and female pigeons different in color are hybridized respectively to obtain F1 generation, and sex is determined for the F1 generation through the color. Pigeon varieties at home and abroad are used as material, part of strains are selected for mating and hybridization, automatic sexing for first-generation hybrids is achieved, 22 automatic female-male mating methods are created, and sex self-distinguishing accuracy is up to 100%. Young pigeons may be subject to sex self-distinguishing before reaching sales age, and the identified female pigeons are used directly to lay eggs; the male pigeons are for sales as broiler pigeons when reaching the sales age; the sex identifying means can be simplified, early male pigeon breeding cost is saved, managing efficiency is improved, the blank of a sex self-distinguishing supporting system for layer pigeons in China is filled, pigeon genetic resources at home and abroad are make full use, and great economic and social benefits are created for the production of layer pigeons 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
