How to confirm ovulation in sows

Before ovulation, sows will open their cervix and release rubbish from the womb, and then they will see some sticky material like snot. When the uterine garbage is exhausted, the vulva is relatively clean, and there is only thin liquid left, it will enter the ovulation period. The time of ovulation can also be determined by sows in estrus. So, how can we promote ovulation in sows?

First, how can we promote sow ovulation?

1. Strengthen the feeding and management of sows. Pay attention to feed some appropriate amount of fish meal, blood meal, bean cake, bone meal, carrots, pumpkins and other protein, minerals and vitamins feed, the effect will be better. If fed properly, sows with piglets are generally in estrus 3-5 days after weaning, and can ovulate and mate normally.

2. Fat empty sows should be reduced to reduce weight. In the process of feeding, fat reduction measures should be taken for over-fat empty sows. Because no matter in what season, sows are too fat to ovulate normally. As a sow for breeding, it is appropriate to keep the body condition of the sow that is not fat or thin.

3. artificial aphrodisiac. In order to promote the normal estrus ovulation of non-estrus sows and infertile sows, artificial estrus measures can be adopted, such as heterosexual induction, control of lactation time, nesting, early weaning, breast massage and hormone stimulation. A better effect can be obtained.
