Management requirements to ensure the delivery of newborn piglets during the delivery period of sows

Sow delivery

Proper care of sows during pregnancy, delivery and lactation can increase the litter weight of newborn piglets, which will ensure that piglets are healthy and grow faster. Taking care of the sows in these periods is also to enable the sows to restore their good performance as soon as possible during the empty period. Sows must have the best nutrition and health during delivery to ensure the expected number of piglets. An appropriate amount of diet should be fed to ensure the good growth and strength of newborn piglets. A pig herd health plan that ensures that sows are at least likely to be infected with disease or do not bring disease to pregnancy is essential to ensure the maximum survival rate of piglets in the first week of birth and grow to the weaning period to the final market. Sow management should be carried out every day, and breeders should treat sows gently.

1. Find out the delivery time of sows. Understanding the average pregnancy cycle of pigs, 92% of sows gave birth naturally on 113-117 days after pregnancy.

two。 Induce sows to give birth smoothly. Induction was performed on sows whose pregnancy was within a day or two of the average pregnancy. Mild prostaglandin products can be used, intramuscular injection of 2 ml, injection time of 7-8 am, in order to allow sows to give birth smoothly on the second working day.

3. Test the delivery time of sows. The day before the sow is induced to give birth, the breeder should check all parturient sows before leaving the barn and install additional insulation lamps and shredded paper on both sides and rear sides of the sow that is about to give birth. The flow of colostrum from the nipple is a sign that the sow is about to give birth.

4. Record the parturition process of sows. On the day of giving birth, check to see if any sows have started the process of giving birth. For those who have finished giving birth, make sure that no piglets catch cold and can suck on colostrum, and record the birth time of the last piglet and the amount of placenta excreted.

5. Help piglets eat colostrum. After giving birth, dry the piglets with shredded paper or dry cloth, put them in an incubator for 30-40 minutes, and then put them on the sows' breasts to eat colostrum. The oxytocin produced by piglets sucking stimulates the uterus of sows to contract further, thus promoting production. It is very important to help piglets eat colostrum as early as possible in the first few hours of birth.

6. Fix the sucking position of piglets. The piglets sucked for about an hour, marked, moved to the incubator, or placed on a heated electric blanket, and the smaller piglets were placed in the front nipples when feeding colostrum.

7. Artificially assisted sow delivery. If the sow does not give birth to a piglet within 30 minutes, but continues to work hard, auxiliary delivery must be carried out. Correct the fetal position with a hand and arm with a plastic cover and obstetric gel; if the sow is no longer responsible and there are signs that some piglets have not been delivered, 0.5-1 ml of oxytocin can be injected intramuscularly to stimulate uterine contraction. Note that the use of oxytocin should not be excessive and must be used at intervals of more than 45 minutes. Injecting 1 ml of oxytocin also helps with the delivery of the remaining piglets and the excretion of the placenta, as well as for sows that are nearing the end of the birth process.

8. Make sure the piglets are breastfed. Before feeding the piglets to other sows, the time for piglets to suck the colostrum of their own sows should not be less than 6 hours to obtain specific maternal antibodies.
