1. Find out when the sow gave birth. Knowing the average gestation cycle of the herd, 92% of sows delivered naturally 113-117 days after gestation. 2. Induced sows to give birth smoothly. Induction of sows within one or two days before and after the average gestation period was induced. Mild prostaglandin preparations can be used, intramuscular injection of 2 ml, injection time is 7-8 am, the purpose is to allow the sow to deliver on the second working day. 3. Test the sow's delivery time. The day before inducing calving on the sow, the breeder should check all labor sows before leaving the pig house. Additional soaking lamps and shredded paper are added on both sides and the back of the sow to be delivered. Milk is a sign that sows are about to give birth. 4. Record sow farrowing process. On the day of birth, check to see if any sows have begun to enter the farrowing process. For those who have completed calving, it should be ensured that none of the piglets catch cold and can suck into the colostrum and record the time of the last piglet's birth and the amount of tires discharged. 5. Help the piglet to eat colostrum. After the piglet has been produced, wipe it dry with shredded paper or a dry cloth, put it in the incubator for 30-40 minutes, and place it on the sow's breast to eat colostrum. Piglet sucking milk causes the oxytocin produced by the sow to stimulate further contraction of the sow's uterus, thereby facilitating production. It is very important to help the piglets eat colostrum as early as possible in the first few hours of the piglet’s output. 6. Fixed piglet sucking position. The piglet licks the milk for about one hour, marking it, moving it to the incubator, or placing it on a heated electric blanket. When the colostrum is fed, the smaller piglets are placed in the front row of nipples. 7. Artificially assisted sows to give birth. If the sow still hasn't delivered a piglet within 30 minutes, but continues to blame, it must be assisted delivery. Correction of the fetal position with a hand and arm with a plastic sleeve and an obstetrical gel applied; if the sow is no longer responsible and there are indications that piglets have not been delivered, 0.5-1 ml oxytocin can be intramuscularly administered Stimulate uterine contractions. Note that the use of oxytocin must not be excessive. Each use must be separated by more than 45 minutes. Injecting 1 ml of oxytocin also helps in removing the remaining piglets and expelling the placenta, which is also useful for sows that are already finishing the farrowing process. 8. Make sure that the piglets are breastfeeding. Before feeding the piglet to another sow, the suckling of the piglets should not be less than 6 hours to obtain the specific maternal antibody.
