First apply cloprostenol and step on the sow’s belly vigorously (stepping as the sow exerts strength). If it still doesn't come down, it may be difficult to deliver or you need to use your hands during midwifery. It's best to wear special long-arm plastic gloves, clean your arms with potassium permanganate, and then apply oil lubricants such as paraffin or paraffin to your hands and arms. Midwives can put their hands into the birth canal, massage the cervix, and slowly pull out the fetus as the sow contracts.

For sows with dystocia caused by abnormal fetal position, midwives can put their hands into the birth canal, push in the hind limbs or forelimbs of the fetus, and remove the fetus. If the sow's birth canal is dry, clean lubricant can be injected into the birth canal. If the fetal position cannot be corrected and a caesarean section is not possible or appropriate, certain parts of the fetus can be amputated and removed.

During the midwifery process, efforts should be made to prevent damage and infection to the birth canal. After assisted delivery, sows should be injected with antibiotics to prevent infection.

After artificial assisted delivery, the sow must be evacuated and then given long-acting oxytetracycline once a day for three consecutive days
