The goal of the sow before breeding is to maximize the number of eggs ovulated. Ovulation number is a basic factor limiting sow litter size, and there is a large difference between the actual and potential reproductive capacity of sows, so it is important to use pig B-ultrasound to observe ovulation number before breeding. Although the number of sow ovulation is related to heredity, it also depends on many factors such as feeding management, fat condition of the sow when weaning, length of Suckling time of the piglets, and whether the sow suffers from reproductive tract diseases, and whether the sow is timely or not.

First of all, we should pay attention to regulating the sow's fat condition. As the saying goes, "empty sow 80% fat, easy to conceive high litter", pig with B-ultrasound observation, keep the sow 7-8 good condition. Pay attention to the full value of the diet, especially pay attention to the adequate quality of green feed in the diet, pigs with B-ultrasound monitoring, adopt a reasonable feeding method, so that sows maintain a suitable condition, can increase the number of ovulation sows, improve the quality of eggs.

Short-term optimal feeding of sows before breeding can significantly increase ovulation rate. Appropriate feeding stimulation 10-14 days before breeding, by stimulating the secretion of gonadotropin, can increase the ovulation number of sows 1-2 and improve the litter number, especially for lean sows, "aphrodisiesis supplement" effect is better, which is the best "scouring" effect, can be clearly observed through pig B-ultrasound. At the same time, pay attention to the temperature before breeding to be appropriate. The appropriate heat can encourage the sow to ovulate more. However, too high temperature will affect the sow can not ovulate normally. In production, the temperature in the house should be adjusted with the change of climate, which has an important role in promoting normal estrus and ovulation of sows, and can also be determined by the observation of pigs with B-ultrasound.
