What are the best ways to raise pigs?

Breeding pigs should be carried out before feeding 1 hour or 2 hours after feeding in the morning and evening. The mating ground should be flat and quiet, and there should be no sharp objects around to avoid stabbing the sow. The length and width of the breeding farm should be twice the length of the breeding pig. If boars are kept in a single enclosure and the enclosure is closed, sows can be driven to the boar enclosure to breed. This is very important for the boar breeding for the first time, and at the same time, it is necessary to arrange the gentle miniature sow to breed with it. Try to avoid sows with bad estrus and strong aggression, so as not to be attacked by sows when climbing the hill, causing psychological obstacles and fear of breeding from now on.

When mating, necessary assistance should be given. When the boar climbs behind the sow, it should pull the sow's tail in time to prevent the boar's penis from rubbing outside for a long time or causing sexual intercourse interruption. Keep the environment quiet during mating, and it is forbidden to make noise and whip boars. After mating, male sows cannot bathe or feed immediately. After breeding, it is necessary to fill in the breeding registration in time and accurately record the breeding date and the number of ears of male and female pigs.

In addition, boars are livestock that ejaculate many times, and the mating time can be as long as 15 ~ 20 minutes, and the cumulative ejaculation time is about 6 minutes, which consumes a lot of physical strength. If the mating amount of a boar is not large, it can be allowed to complete mating without controlling its ejaculation times; However, when the mating burden of boars is large and concentrated, in order to reduce the physical consumption of boars, it is appropriate to control the ejaculation times of each mating to 2 times. The method is, when the boar ejaculates twice, slowly push the sow forward. When the boar can't keep up, it will naturally slide down from the sow's back. Never drive a wild boar with a whip. How do you know that boars ejaculate twice? The ejaculation of boars can be judged according to whether the anus is ups and downs. When ejaculating, the boar stops twitching, the testicles tighten and the anus fluctuates constantly. During the ejaculation interval, the boar twitched again, the testicles relaxed and the anus stopped fluctuating. According to this, the number of ejaculations can be accurately judged. Then, will controlling the number of ejaculations to 2 times affect the conception rate and litter size of sows? I won't. The cumulative ejaculation time of boars is about 6 minutes, but 80% of the sperm in a mating is ejected within 2 minutes before ejaculation. Therefore, as long as the boar ejaculates twice, it can completely guarantee the normal pregnancy of the sow. This has been confirmed in practice.
