Method for breeding auto-sexing pigeon new lines

Abstract

The invention relates to a method for breeding auto-sexing pigeon new lines, which is characterized in that a female yellow feather pigeon and a male white feather pigeon are selected to mate, so a generation F1 is generated; a male crimson feather pigeon and a female yellow feather pigeon are selected from the generation F1 to back cross, so a generation F2 is generated, and a plurality of types of feather color individuals are separated from the generation F2; the female yellow feather pigeon is selected from the generation F2, and is crossed fixed with a male silver pigeon or a male brown pigeon, and the individuals of a female yellow feather pigeon, the male silver pigeon or the male brown pigeon are selected from the later generation of the female yellow feather pigeon and the male silver pigeon or the male brown pigeon; the sex-linked genetic genes of the female yellow feather pigeon, the male silver pigeon or the male brown pigeon are screened, and homozygotic type individuals are selected and remained; the female yellow feather pigeon, the male silver pigeon or the male brown pigeon of the homozygotic type are subjected to family selection, individual selection and the like; and the two steps are repeated until two auto-sexing pigeon new lines are bred from the female yellow feather pigeon, the male silver pigeon or the male brown pigeon in a stable genetic manner. The adoption of the method can be dispensed with a sexing step, so the breeding cost is saved to the maximum extent.

Description

technical field [0001] The invention relates to a method for breeding pigeons, in particular to a method for cultivating new strains of self-separated male and female pigeons. Background technique [0002] With the expansion of the pigeon breeding industry in my country, the problem of gender identification of meat pigeons has become prominent. Technicians always try their best to conduct detailed research on the anus, body shape, behavior and feather characteristics of pigeons, and propose some identification methods. But the results are always unsatisfactory, especially the young pigeons and the young pigeons within three months are more difficult to distinguish between sexes. Therefore, in pigeon farms and breeding farms, the time to reserve seeds is often determined according to the growth and development of young pigeons, and it is seldom taken into account whether the ratio of male to female is appropriate. The gender identification of birds is a worldwide problem. Som...

Problems solved by technology

The gender identification of birds is a worldwide problem. Some people propose to use DNA molecular markers to identify the sex of pigeons. Due to expensive equipment, professional and technical personnel are required to operate, the identification speed is slow, and the identification cost is relatively expensive. Factors such as restricting this technology in the pigeon breeding industry widely used in
