Embodiment 1

[0015] A method for artificial insemination of livestock pigs, comprising the following steps:

[0016] (1) Semen collection: Massage the glans of the boar’s penis with your hands to discharge the prepuce fluid, wipe the foreskin opening with a towel or paper towel, hold the penis with one hand, apply pressure on the helicoid at the front of the penis, and hold the penis with the other hand. The semen collection cup of the heat preservation facility receives the semen;

[0017] (2) Semen inspection: filter the semen once with gauze, check the volume, color and smell of the semen, then dip a sterilized thin glass rod into a drop of the filtered semen, put it on a glass slide, and cover it Sperm motility is checked under a microscope on slides, and the concentration of semen is checked with a spectrophotometer;

[0018] (3) Dilution of semen: Preheat the semen and diluent in a thermostat at 37°C, then slowly pour the diluent into the semen along the wall of the cup, and at the ...

[0023] A method for artificial insemination of livestock pigs, comprising the following steps:

[0024] (1) Semen collection: Massage the glans of the boar’s penis with your hands to discharge the prepuce fluid, wipe the foreskin opening with a towel or paper towel, hold the penis with one hand, apply pressure on the helicoid at the front of the penis, and hold the penis with the other hand. The semen collection cup of the heat preservation facility receives the semen;

[0025] (2) Semen inspection: filter the semen once with gauze, check the volume, color and smell of the semen, then dip a sterilized thin glass rod into a drop of the filtered semen, put it on a glass slide, and cover it Sperm motility is checked under a microscope on slides, and the concentration of semen is checked with a spectrophotometer;

[0026] (3) Dilution of semen: Preheat the semen and diluent in a thermostat at 37°C, then slowly pour the diluent into the semen along the wall of the cup, and at the ...

Embodiment 3

[0031] A method for artificial insemination of livestock pigs, comprising the following steps:

[0032] (1) Semen collection: Massage the glans of the boar’s penis with your hands to discharge the prepuce fluid, wipe the foreskin opening with a towel or paper towel, hold the penis with one hand, and apply pressure on the helix at the front of the penis, and hold the penis with the other hand. The semen collection cup of the heat preservation facility receives the semen;

[0033] (2) Semen inspection: filter the semen once with gauze, check the volume, color and smell of the semen, then dip a sterilized thin glass rod into a drop of the filtered semen, put it on a glass slide, and cover it Sperm motility is checked under a microscope on slides, and the concentration of semen is checked with a spectrophotometer;

Abstract

The invention discloses an artificial insemination method for pigs. The method includes the following steps: (1) semen collection; (2) semen inspection; (3) semen dilution; (4) semen storage; (5) insemination; and (6) secondary insemination. The method has the beneficial effects that the artificial insemination technology greatly improves the conception rate and controls the proportion of males and females of the produced piglets, so that the yield of the sows is as high as 75%, the method improves the utilization rate of high-quality boar, reduces the cost of breeding, and reduces the spreadof reproductive tract diseases.

Description

technical field [0001] The invention relates to an artificial insemination method for pigs. Background technique [0002] The artificial insemination technology of pigs began in the 1930s in the 1920s, and in the 1950s in my country, but it did not become popular until the 1990s. At present, this technology has become one of the main means of breeding pigs. The use of artificial insemination technology is conducive to the promotion of new breeds of pigs. It can reduce the labor intensity of mating sows, save the time spent on mating, avoid diseases caused by natural mating of males and sows, and improve the growth rate and lean meat of pigs. Increase the disease resistance of pigs, increase the number of litters produced by sows, improve the survival rate of piglets, reduce the number of boars, save feed, reduce breeding costs, and improve economic benefits. However, in the actual operation process, due to improper operation methods, it is easy to cause semen pollution and...
