1. Removal of ectoparasites: If a sow is found on a sow, use a 2% solution of trichlorfon for spraying to prevent it from being transmitted to piglets after delivery.
2, change the feed: sows 10 to 15 days before childbirth, gradually changed the feeding lactation diet, to prevent sudden changes in the postpartum caused by indigestion and piglets diarrhea.
3. Addition and subtraction of feed: If the sow has a good sensation and the breast enlargement is obvious, then the amount of feed should be gradually reduced in 1 week before birth, and it should be reduced to half of the diet by 1 to 2 days before birth; and the coarse material and slag should be reduced. Such as large-scale feed, so as not to oppress the fetus, or cause constipation of prenatal sows affect the delivery. Stop feeding at the time of finding labor symptoms, as long as bean cake bran soup. If sows have poor lyrical condition and their breasts are dry, they should not only reduce their feed but must also feed soybean cakes and other protein prolactin feeds to prevent the sows from having milk after delivery.
4, moderate exercise: 1 week before delivery should stop long-distance sports, instead of in the pig house or sports grounds to get around to avoid the fierce pursuit, collision caused by miscarriage or stillbirth.
5. Moved into the delivery room: 3 to 5 days before delivery, the sow will be moved to the delivery room to familiarize it with the new environment and avoid the death of the fetus due to labor suffocation. However, do not move the sows into the delivery room prematurely to avoid contaminating the production circle and reducing the sow's physical strength.
6. Observe: Observe the sow's dynamics at any time before the sow is giving birth one week before delivery, strengthen nursing care, and prevent accidents such as premature birth and accidental delivery.
