The artificial insemination technology of pigs is the simplest and most effective method for the breeding of breeding pigs and the production of commercial pigs.
It is an important means for scientific breeding and modernization of pig production.
There are many advantages to artificial insemination in pigs .
• Improve the utilization rate of excellent external boars and save the feed and costs of raising boars.
Natural mating once, the boar’s ejaculation can only be matched with a sow.
Using artificial insemination technology, the boar’s ejaculation can be matched with 10 to 30 sows.
• Pig artificial insemination is good for pig genetics and joint breeding
Artificial insemination can solve the problem of large number of pig farms and small scale, and realize the joint breeding of pigs.
It is also one of the most economical and effective means to improve pig breeding efficiency and improve breeding system.
Artificial insemination by the semen of the excellent boars can accelerate the genetic progress of pig breeding, increase the coverage of excellent genes in the herd, increase the growth rate of the herd, improve the uniformity of the pigs, and improve the quality of the pork.
Vigorously carrying out the application and promotion of artificial insemination technology of external pigs can quickly and safely exchange the genetic resources of the elite breeding pigs in the form of semen, so that the joint breeding of a large range of pigs can be realized in the shortest time.
• Artificial insemination is good for the layout of the variety.
Artificial insemination can fully play the role of excellent lean meat boars and accelerate the production of lean meat pigs.
• Overcome the difference in pig size and make full use of the advantages of hybrid pigs
In the case of natural mating, a large boar is difficult to breed with a small sow.
Using artificial insemination technology, as long as the sow is stable, it can overcome the above difficulties and choose breeding according to needs.
This is conducive to the full play of the conservation and heterosis of high-quality breeding pigs.
• Reduce the spread of disease
Boars and sows that are artificially inseminated are generally pigs that have undergone health checks.
As long as the breeding in strict accordance with the operating procedures, reduce pollution during the process of semen collection and semen treatment, it can reduce some diseases, thereby increasing the conception rate and litter size of the sow.
• Overcome time and area constraints
With artificial insemination, boar semen can be processed for a certain period of time.
This allows the estrus sow to be inseminated at any time. The farmer can purchase semen (or frozen essence) without introducing boars, and promote the social and economic benefits of the pig industry.
• Save manpower and improve economic efficiency
Compared with natural mating, the number of breeding boars is relatively reduced, saving some labor, feed, housing and funds.
Pig artificial insemination technology can also improve the conception rate of sows, because the boars used in artificial insemination are strictly selected, and each time after the fine collection, they must undergo microscopic examination, which is difficult to do with natural mating.
Shortcomings of artificial insemination
If the technique of artificial insemination is not high, it is likely that the sow will have metritis, low conception rate and low litter size.
It is recommended to learn artificial insemination techniques first.
Then, a small-scale artificial insemination test is carried out, and the technology is matured
