It is very important to ensure that the sow's husbandry and management and the survival rate of the piglets are improved.
The sows were gradually fed lactation diet for 10-15 days before delivery to prevent indigestion and piglet diarrhoea caused by sudden changes in the postpartum period. Addition and subtraction of feed If the sow has a good sensation and the breast enlargement is obvious, the amount of feed should be gradually reduced in 1 week before birth, and 1â„2 of the prenatal diet should be reduced by half; and the large volume of coarse material and bad residue should be reduced. Feeding so as not to oppress the fetus or causing prenatal constipation to affect delivery.
When the symptoms of labor were found to stop feeding, only the bean cake bran soup was fed. 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.
Moderate exercise. The long-distance exercise should be stopped 1 week before delivery, and the activities should be carried out in the vicinity of a pig house or a sports field to avoid a fierce catch-up or collision and cause miscarriage or stillbirth.
In addition to ectoparasites. If a sow is found on the sow, use a 2% solution of trichlorfon to spray it off to prevent it from being transmitted to the piglets after delivery.
