Analysis of advantages and disadvantages of artificial insemination in pigs


Pig artificial insemination refers to a method of mating boar semen with artificial aids, testing, processing, and preservation through the laboratory, and then using boar semen into the genital tract of the estrus.


1. Improve seed utilization

Artificial insemination of pigs is the most effective means to improve breeds of pigs, which can promote the renewal of breeds and increase the quality and uniformity of commercial pigs. Through the artificial insemination technology, the quality genes of excellent boars can be rapidly promoted, and the poor boars can be eliminated, the superiority can be eliminated, the breeding amount of male boars can be reduced, the breed line of breeding pigs can be improved, and the production performance of commercial pigs can be improved. At the same time, poor boars can be eliminated, the superiority can be eliminated, and the feeding amount of boars can be reduced, thereby reducing the pig raising cost and achieving the purpose of improving the efficiency.

2. Overcome the difference in size, make full use of heterosis

Using artificial insemination technology, as long as the estrus is stable, it is possible to overcome the difference in the size of male and female sows and the difficulty of breeding due to the preference of male and female sows, and to perform timely breeding according to needs, which is conducive to the utilization of high-quality breeding pigs and the full utilization of heterosis. .

3. Reduce the spread of the disease

The male and female pigs undergoing artificial insemination are generally pigs that have been tested for blood and are healthy. As long as they are strictly in accordance with the artificial insemination procedures, minimizing the pollution during the sperm extraction and semen processing, the incidence of some diseases can be reduced. And spread so as to increase sow fertility, litter size, and utilization. However, some diseases transmitted through semen can be transmitted through artificial insemination. Therefore, boars that are artificially inseminated should undergo the necessary disease tests.

4. Overcoming differences in time and area, timely breeding

The use of artificial insemination can overcome the estrus of the sow but no boar can be used, or need to be improved but the introduction of boars is not easy and other difficulties, and the boar semen can be processed and stored for a certain period of time, at any time for the estrous sows insemination breeding, It is easy to carry, economical, and can ensure quality and timely breeding, so as to promote the social and economic benefits of the pig industry.

5. Save manpower, material resources, financial resources, and increase economic efficiency.

Compared with natural insemination and natural mating, the number of breeding boars has been relatively reduced, which has saved some of the labor, feed, barnage, and funds. Even if a suitable boar station is re-established, the total economic benefit will still increase. Porcine sperm will create more economic benefits.

Disadvantages: If the production level of the pig farm itself is not high and the technology is not closed, the use of artificial insemination is likely to result in increased sow myometitis, low fertility rate and fewer litters. It is recommended that technicians should first learn the technology and then conduct small-scale artificial insemination tests, or adopt a combination of natural mating and artificial insemination. With the continuous improvement of the level of production and technology, it will be promoted.
