How are pigs bred?

The best place for male and sow mating is near the sow house. It is absolutely prohibited to mate near the boar house to avoid causing disturbances to other boars.

When male and female pigs mate, artificial assistance should be provided. When the boar climbs onto the sow, he should quickly pull the sow's tail from the side to prevent the boar's penis from rubbing the sow's tail, causing injury or external ejaculation. When the boar's penis cannot enter the vagina smoothly after several attempts, the boar's foreskin can be held with hands to guide the penis into the sow's vagina. Keep the environment quiet during mating, and it is strictly forbidden to make loud noises or whip the boar. After mating, gently press the sow's waist with your hands to prevent the semen from flowing out. After the breeding is completed, the ear number and breeding date of the breeding boar should be registered promptly in order to calculate the expected date of delivery and to find the pedigree of the offspring in the future.

Boars are domestic animals that ejaculate multiple times. One mating time can be as long as 15 to 20 minutes. The cumulative time of ejaculation is about 6 minutes, which consumes a lot of physical strength. If the breeding number of boars is not large, you do not need to control their ejaculation and let them finish breeding. However, when the breeding burden of boars is large or concentrated, in order to reduce physical exertion, it is appropriate to control the number of ejaculations per mating to 2 times. The method is: after the boar ejaculates twice, slowly drive the sow forward. When the boar cannot keep up, it will naturally slide off the sow's back. Do not use a whip to drive the boar down. When the boar ejaculates, it stops twitching, its testicles tighten, and its anus keeps vibrating. During the interval between ejaculation, the boar resumes twitching, the testicles relax, and the anus stops vibrating.
