Breeding technology of sows before parturition

In order to ensure the smooth production of sows, the farmers need to make more observation on the health status of sows before they give birth, concentrate the sows on the professional pig breeding equipment, and take certain measures to help the sows to give birth to piglets smoothly. Today, let's learn from Xiaobian about the breeding technology of sows before delivery.
1. Observe the dynamic of sows. The sows should be observed at any time one week before delivery, and the nursing should be strengthened to prevent accidents such as early delivery and no delivery.
2. Guide sows to exercise properly. The long-distance movement should be stopped one week before delivery, and the activity should be around the pigsty or playground instead to avoid abortion or stillbirth caused by fierce pursuit and collision.
3. Gradually change the feed. In order to prevent dyspepsia and diarrhea of piglets caused by sudden change of feed, lactation feed should be changed gradually 10-15 days before delivery.
4. Add and subtract feed according to the actual situation. If the sow is fat and the breast is swollen obviously, the feeding amount shall be reduced gradually in the first week of prenatal period, and half of the ration shall be reduced in the first to second days of prenatal period; and large volume feed such as coarse feed and trough residue shall be reduced, so as not to oppress the fetus, or cause constipation of the prenatal sow to affect the delivery. Stop feeding when labor symptoms are found, as long as soybean cake bran soup. If the sow is poor in fat and the breast is dry, it should not only not reduce the feed, but also feed protein milk promoting feed such as soybean cake to prevent the sow from having no milk after delivery.
5. Move into the delivery room in advance. The sows should be moved into the delivery room 3-5 days before delivery to make them familiar with and accustomed to the new environment, so as to avoid the death of asphyxia caused by severe tossing before delivery. But don't move sows into the delivery room too early to avoid polluting the labor circle and reducing the physical strength of sows.
6. Eliminate parasites in time. If the sows are found to have lice or scabies, they should be removed by spraying with 2% of them, so as not to pass them to the piglets after delivery.
