Fertilization method for Tibetan chicken

Abstract

The invention discloses a fertilization method for Tibetan chicken. The method comprises the following steps: (1) selection of breeding chicken: breeding cocks and breeding hens are selected according to a quantity ratio of 1:(1-20); (2) semen collection of the breeding cocks: semen collection is performed on the breeding cocks in the afternoon, a semen collection cup is used for collecting semen in the copulatory organ position above a cloaca of each cock; and (3) insemination of breeding hens: insemination is performed on the breeding hens in the afternoon, an insemination device filled with the semen is inserted into the vagina of each hen for semen injection, and the hen is placed back to a cage after the insemination is finished. The fertilization method for the Tibetan chicken disclosed by the invention adopts standardized operation, and is not influenced by defects such as unstable fertilization rate, large fluctuation and the like of wild pairing of the Tibetan chicken, mass Tibetan chicken breeding and cultivation with stable and high fertilization rate can be achieved, and the breeding cost is reduced effectively.

Description

technical field [0001] The invention relates to a fertilization method, in particular to a fertilization method for Tibetan chickens, and belongs to the field of animal biology. Background technique [0002] Tibetan chicken is a kind of chicken that lives in the pure and pollution-free snow-covered plateau. The amino acid profile in milk is very similar, so it is a high-quality protein source, especially the content of collagen is significantly higher than that of other livestock and poultry meat products, with rich nutrition and comprehensive structure. [0003] At present, Tibetan chicken breeding is still in the primitive and backward breeding mode of free-range farming by farmers, and its annual slaughter volume cannot meet the needs of the national market at all. At the same time, with the development of commercial chicken production and the improvement of traffic conditions, people in the breeding areas have widely introduced inland fine-bred broilers, and the number ...

AI Technical Summary

Problems solved by technology

[0004] The traditional breeding of Tibetan chickens adopts the natural fertilization method of small flocks, and achieves fertilization through natural mating, but this fertilization method has many defects, mainly including: the fertilization rate is unstable and fluctuates greatly, and the fertilization rate of natural fertilization is different from that of males. 1. The state of the hen has a lot to do with it, and it is impossible to maintain a stable fertilization rate; it is not conducive to breed selection, because natural mating is based on a small group, and it is impossible to achieve one-to-one correspondence between roosters and hens, making it difficult to establish pedigree , it is impossible to achieve breed selection to improve the production performance of Tibetan chickens; it is easy to cause damage or pollution to the breeding eggs
