Feeding management points during sow delivery

First, the diet should be reasonable

One week before the sow is delivered, the feed is increased or decreased depending on the sow's sensation and breast development. Sows with good sensation and enlarged breasts should gradually reduce the diet to 70% to 80% of the original diet, mainly reducing green and juicy feed and some concentrates to prevent excessive milk in the first few days after delivery. Can not cause mastitis, or because the milk is too thick, causing piglets to squat. Thin sows do not have to reduce the amount of material. If the breast enlargement is not good a few days before delivery, they should be fed with some prolactin containing more protein or some prolactin to prevent postpartum milk or lack of milk. 1 to 2 days after childbirth, the sow is very tired and has a bad appetite. In order to restore the sow to the physical strength and restore the uterus as soon as possible, it is impossible to feed the large-volume, difficult-to-digest feed, and should feed some millet porridge, bran porridge, etc. Liquid feed, feed some green materials. After 3 days, the feed was gradually increased, and the normal feed amount of the lactating sow was reached by 7 days.

Second, the exercise should be moderate

Sows should reduce their movements 3 to 5 days before giving birth, and only be free to move in the circle, unable to catch up, scare, and circle. Within 3 days after delivery, because the sow is weak and the piglets are sucking milk frequently, it is best to let the sow rest in the circle. After 3 days, if the weather is good, the sow can be allowed to go out.

Third, timely delivery

It is necessary to pay attention to the characteristics of sows' labor. When the sow's nipples are left and right, the genital area is red and swollen, the sides of the tail are sunken, and the squatting is slow. It means that it will be delivered in about 3 days. After the start of the frequent urination, it is necessary to give birth after 6 to 12 hours. It is necessary to prepare for the delivery and to timely deliver the product. When the piglets are produced, raise the piglets with both hands and immediately remove the mucus from the mouth and nose of the piglets to avoid suffocation. Then use the hay and then dry the pig body mucus with a towel or sack to avoid freezing the piglets. Then break the umbilical cord, first squeezing the cord blood to the abdomen 3 to 5 cm, and tearing the umbilical cord with both hands. The umbilical cord should be disinfected with iodine before and after the operation. If the umbilical cord is broken after delivery, the umbilical cord should be sprayed with 5% iodine in time, and then placed in a production box with hay. For the suspended piglets, alcohol can be used to stimulate the nose, acupuncture at the acupoints, and blowing to the nose to rescue.

Fourth, care should be careful

7 to 10 days before the sow's prenatal period, the maternal should be thoroughly cleaned and disinfected. After drying, the mat should be cut short. On the day of the birthing action, it is advisable to stop feeding. Do not feed during childbirth. If the delivery time is too long, the sow is thirsty and can be fed clean drinking water. After childbirth, always pay attention to the sow's breathing, body temperature, excretion and breast condition, keep the delivery room quiet, clean the blood of the hindquarters with a clean towel or straw, wash the breast with warm water, and massage at the same time. After the placenta is completely discharged, the birth attendant should quickly remove the placenta, stillbirth, contaminated bedding, etc., to prevent the sow from swallowing and causing postpartum indigestion or developing the evils of swallowing piglets.
