Embodiment 1

[0018] 1) Artificial feeding of roosters before semen collection: select 55-week-old artificial insemination roosters, add feed additives in the ratio of 1.5wt% to conventional feed, feed continuously for 7 days and then stop for 7 days. Chicken 68 weeks old;

[0019] 2) Semen collection: the breeding cock obtained in step 1) is fed for semen collection training, and the semen of the breeding cock is tested for quality and pullorum 15 days before fertilization, and the breeding cock that meets the requirements is retained, In a quiet environment, cut off the feathers around the cloaca of the breeder rooster, and the diameter of the exposed area is 4-5cm, which can prevent chicken manure, feather crumbs or dust from falling into the semen collection cup and cause semen pollution, resulting in fertilization If there is a defect with a low rate, the collectors will grab the rooster with the tail forward and the head backward, and fix the rooster under the armpit of the collector....

Embodiment 2

[0024] 1) Artificial feeding of roosters before semen collection: select 55-week-old artificial insemination roosters, add feed additives in the ratio of 2.0wt% to conventional feed, feed continuously for 7 days and then stop for 7 days. The chicken is 68 weeks old or the production cycle is over;

[0025] 2) Semen collection: the breeding cock obtained in step 1) is fed for semen collection training, and the semen of the breeding cock is tested for quality and pullorum 18 days before insemination, and the breeding cock that meets the requirements is retained, and Cut off the feathers near the anus of the breeding cock, and collect the semen of the breeding cock with a semen collection cup before insemination;

[0026] 3) Dilute semen: use 2 times the volume of semen to slowly add semen diluent along the wall of the semen collection test tube into the semen collection test tube, then gently rotate the semen collection test tube, repeat 4 times;

Embodiment 3

[0030] 1) Artificial feeding of roosters before semen collection: select 55-week-old artificial insemination roosters, add feed additives in the ratio of 1.8wt% to conventional feed, feed continuously for 7 days and then stop for 7 days. The chicken is 68 weeks old or the production cycle is over;

[0031] 2) Semen collection: the breeding cocks obtained in step 1) are fed for semen collection training, and the semen of the breeding cocks is tested for quality and pullorum 20 days before insemination, and the breeding cocks that meet the requirements are retained, In a quiet environment, cut off the feathers around the cloaca of the breeder rooster, and the diameter of the exposed area is 4-5cm, which can prevent chicken manure, feather crumbs or dust from falling into the semen collection cup and cause semen pollution, resulting in fertilization If there is a defect with a low rate, the collectors will grab the rooster with the tail forward and the head backward, and fix the ...

Abstract

The invention provides an artificial insemination method of breeder cocks. The method comprises the following steps: 1) artificially feeding breeder cocks before semen collection, namely selecting 55-week-old artificial insemination breeder cocks, adding feed additives to the conventional feed according to a ratio of 1.5-2.0wt%, feeding the breeder cocks until the breeder cocks are at the age of 68 weeks or the production cycle is ended according to a feeding procedure of continuously feeding for 7 days and later stopping for 7 days; 2) collecting semens; 3) diluting the semens, namely using semen diluents of which the volume is 2-4 times of that of the semen and slowly adding to semen collecting test tubes along the tube walls of the semen collecting test tubes, and then gently turning the semen collecting test tubes and repeating for 3-4 times; 4) carrying out artificial insemination, namely turning the anus of hens by anus turning members, transferring the diluted semens to deferent ducts by inseminators, and then gently inserting the deferent ducts into fallopian tubes of the hens by the inseminators and conveying the semens in the deferent ducts to conveying pipes, so as to realize the artificial insemination. The artificial insemination method disclosed by the invention is high in semen viability and insemination rate.

Description

technical field [0001] The invention belongs to the technical field of poultry breeding, and in particular relates to an artificial insemination method for breeder chickens. Background technique [0002] With the development of the modern poultry industry, the scale and intensification of poultry farming are getting higher and higher, and the artificial insemination of poultry is becoming more and more important. The main advantages of chicken artificial insemination technology are to accelerate the process of improved breeds, improve the utilization rate of excellent breeders, reduce the amount of breeding cocks, save feeding costs, increase the insemination rate and increase the number of chicks provided by each hen, and use disease control, etc. Wait. [0003] The artificial insemination technology of breeders is an indispensable means in modern breeding and production. Due to the high density of poultry sperm and the small amount of semen collected, insemination after d...
