Embodiment

[0015] The artificial insemination method of the fine breed pig of the present embodiment, it may further comprise the steps:

[0016] (1) Semen collection: The collection is carried out in a collection room with a temperature above 15°C. After introducing the boar to the dummy sow and performing mating actions, the operator massages the glans of the boar’s penis with his hands to discharge the prepuce fluid, and then cleans it with a towel Or wipe the foreskin mouth clean with a paper towel, hold the penis with one hand, apply appropriate pressure on the helix at the front end of the penis, and hold the semen collection cup with heat preservation facilities in the other hand to collect the semen;

[0017] (2) Semen inspection: Filter the collected semen with 3-4 layers of gauze to detect the amount, color and smell of the semen. On the glass slide, cover with a cover glass and check the sperm motility under a microscope at 250-400 times. The slide and cover glass have been pr...

Abstract

The invention discloses an artificial insemination method of a thoroughbred pig, comprising the following steps: collecting semen; inspecting, diluting and storing the semen; inseminating semen; inseminating semen secondarily; and the like. In the step of inseminating semen secondarily, a semen inseminating pipe which is larger at the upper part and smaller at the lower part is deeply inserted inside the uterus of a sow, the conception rate is greatly increased, and the proportion of male piglets to female piglets is controlled, so that the productive rate of the sow reaches up to 75%, the utilization rate of high-quality boars is improved, the cultivation cost is reduced, and the propagation of reproductive track diseases is reduced.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular 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 i...
