In order to promote normal estrus ovulation in non-estrus sows and infertile sows, the following measures can be taken on the basis of strengthening feeding and management:

1. Temptation: use test boars to chase sows that have not been in estrus for a long time, or keep boars and sows in the same circle. Boar contact, climbing and other stimuli can promote estrus and ovulation.

two。 Hormone aphrodisiac: commonly used hormones are pregnant horse serum, chorionic gonadotropin and synthetic estrogen.

3. Breast massage: massage the breast for 10 minutes every morning for 3 to 5 days, which can promote the sow to be in estrus.

4. Loop: raising non-estrus sows in coop with estrus sows can promote oestrus ovulation through the climbing of estrus sows. Strengthening exercise is also beneficial to sows in estrus.
