It is very important to ensure that the sows have good husbandry and improve their survival rate.
1. In addition to ectoparasites. If a sow is found on the sow, use a 2% solution of trichlorfon for spraying to eliminate it from passing to the piglets after delivery.
2. Transform the feed. The sows are gradually fed with feed during lactation 10-15 days before delivery to prevent indigestion and piglet diarrhoea caused by postpartum mutant feeds.
3. 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 the week before delivery, and half of the diet should be reduced to 1-2 days before delivery, and large-scale feed such as coarse material and bad residue should be reduced to avoid oppression. Fetus or constipation causing prenatal sows to affect childbirth. When the symptoms of labor were found to stop feeding, only the bean cake bran soup was fed. If the sows have a poor lyrical condition and the breasts are dry, they need to be fed with protein, such as soybean cake, to prevent the sows from having milk after delivery.
4. Moderate exercise. One week before delivery, you can enjoy activities in a pig house or on a sports field. Avoid fierce pursuit and collision and cause miscarriage or stillbirth.
5. Move into the delivery room. The sow is moved to the delivery room 3-5 days before the birth, making it familiar with and accustomed to the new environment, to avoid prenatal stress caused by fetal suffocation death, but do not prematurely move the sow to the delivery room, so as not to pollute the production circle.
6. Observe the observation. The sows should observe the dynamics of the sows at any time during the week before giving birth, strengthen nursing, prevent premature calving, and no accidents such as consignment.
