Methods and methods of pig breeding

   (1) monogamy is called monogamy when sows mate with boars only once after they are in estrus. Only

To have rich experience in the implementation of monogamy, pregnancy can be achieved. If you are inexperienced, especially if you learn mating techniques for the first time, it is best not to use single mating.

   (2) repeated breeding means that sows are mated twice with boars during estrus. Specifically, the sows were mated for the first time on the second or third day of estrus, 8: 12 apart.

When I was young, I deserve a second time. Young sows were mated once in the morning and again the next morning, once in the morning after oestrus, and once in the afternoon with repeated breeding, with a conception rate of 85%.

The picture shows: pig

   (3) double breeding

At 18-24 hours after estrus, two boars of different breeds were used to breed, and the time of the two mating was 10-15 minutes apart. Double breeding is not used in breeding farms, but only in commercial pig farms.

   (4) multiple mating sows were mated with boars for 3 times after estrus, the first 12 hours after estrus, the second 24 hours after estrus, and the third 36 hours after estrus.

Hours. Breeding boars can be one or more.

   said that repeated breeding is commonly used in the above four breeding methods. At present, this method is used in industrial pig farms, and the effect is very good.

There are two methods of    breeding: inbreeding and artificial insemination. Most of the large domestic pig farms use this cross, and there are also methods of combining it with artificial insemination. That is, the first natural mating

(this transaction), the second time of artificial insemination. Either way, it is important for a pig farm to check the quality of semen regularly.
