To reduce the piglet's stillbirth rate at the time of sow farrowing, it is necessary to prevent the sows from prolonging the production process and to minimize the farrowing time. Strengthen feeding and management prevention in production: 1. Control the body condition of the sow during delivery and prevent it from becoming too fat or too thin. The body condition of the sows at the time of childbirth in actual work should be full back, with a flat upper line, without any prominent bones. Below the lumbar vertebrae, there should be a lacune in front of the ribs and in front of the pelvis. Therefore, pregnant sows should be restricted by the fetus in the growth and development of the law 98 days before and the sows are fat and thin, feeding from 100 days of pregnancy to 3 days before the full free to eat, this will not only improve the newborn piglets weight, but also Prevent sows from getting too fat. 2. The sows must be restricted before feeding. In order to reduce the adverse effects of overweight gastrointestinal burden on litter size, sows should start restriction within 3 days before birth (based on the expected date of production). The limiting standard is: 3 kg per head per day on the 3rd day before delivery, prenatal 2 kilograms per day per head, 1 kilogram per day per day on the first day of prenatal day. When sows are farrowing, the farrowing meal is not fed and 0.5 kilograms are fed every other day. For example, the sow gives birth in the morning, and the sow in the morning. Stop feeding, feed 0.5 kg in the afternoon, give birth in the afternoon, stop feeding in the afternoon, feed 0.5 kg in the morning on the first postpartum, feed 0.5 kg in the afternoon, 2 kg per head on the 2nd day after delivery, and post 3 days after delivery 3 kilograms per day, 4 days after delivery - weaned to eat freely. That is, the number of prenatal restrictions is more or less, and postpartum feeding is increasing from less to more to prevent postpartum indigestion of sows. 3. Prevent sows from prenatal constipation. It is suggested that 1% sodium sulfate and 0.5% rhubarb soda powder should be mixed into the feed 1 week before and after the sow to make the feces of the sow soft and moist, which will facilitate the smooth movement of the defecation. If the conditional pig farm can use lactation, better. 4. In summer, it is necessary to strengthen the sunstroke prevention and cooling of pregnant sows, especially the sows in the later stage of pregnancy and the sows in the upper part of the breeding bed. The pregnant sows are limited in size and have high density and heat dissipation, especially during the late pregnancy. Eat more, increase body heat after eating, body temperature rose about 0.5 °C before eating, reaching 39.5 °C, when the sow body temperature of 102-110 days of pregnancy maintain the temperature for a long time, the piglet death rate increased at the time of delivery, so when When the ambient temperature reaches 30°C or above, it is recommended that the spray temperature be reduced for the pregnant sows to be bred at half an hour intervals, flushing water for the laboring sows in the delivery room, and minimizing the effect of heat stress on the sows. 5. For the farrowing house, keep the house as quiet as possible, especially for the primiparous gilts. When the sire is restless, it can be helpful to massage the breasts to make them quiet. 6. The piglets dry the mucus after birth. After drying the coat, they should immediately be placed next to the sow's breasts to receive milk. Through the piglets' continuous sucking of the nipples, the sow's hypothalamus can be stimulated to secrete oxytocin and cause the uterus to contract. This not only helps Smooth delivery and shortening of labor will also help milk discharge. 7. Do a good job in vaccination to prevent sow reproductive disorders and timely treatment of sick pigs, especially fever sows.
