Sows usually do not need help during childbirth, because midwifery will increase the risk of infections of the birth canal, but it is necessary to carry out artificial midwifery when it is difficult to produce, and it is difficult to determine whether midwifery is needed and when it is used. The midwifery process is not simple. Put your hand into the birth canal to pull out the baby. The details of artificial birth assistance are described below.

Determine whether a sow is difficult to produce, first to see if it is irritated and extremely nervous, and then see if the birth interval is greater than 45 minutes, depending on the degree of abdominal fullness (whether there is a piglet), and finally determine the sow's birth according to its number of litters. Is it over? If the following three conditions occur in the sow's delivery, it is likely to be difficult to deliver.

1. One or a few piglets have been born, but the sow has no longer exerted force for more than 45 minutes.

2. The sow has taken responsibility, but no piglets have been produced for at least 45 minutes.

3. The mucus of all piglets has dried up, but the breeder is still able to identify piglets in the sows.

The birth interval of two adjacent piglets must have an accurate time record. When it is determined that midwifery is needed, prepare for midwifery:

1. Apply warm water and disinfectant (Bergon, Chlorhexidine, etc.) or soap to wash sow's cunt and surrounding parts to remove organic matter and dirt.

2. The midwife's hands and arms should wear new sterilized long arm gloves and apply a lubricant (such as liquid paraffin).

Sows giving birth during childbirth

The hand is rolled into a cone, and the arm can enter when the sow does not blame and the birth canal expands (if the sow is lying right, use the right hand, otherwise the left hand.), slowly through the vagina, into the cervix (uterus in the pelvis Right above or just below the edge). As soon as a hand enters the uterus, the head or hind leg of the piglet can be touched, and the piglet can be pulled out slowly by grasping the hind leg or head or chin of the piglet according to the fetal position.

Sow delivery considerations

Do not pull the placenta out with the piglet. Do not injure the vulva, cervix, and uterus during the pullout; if the two piglets are stuck at the intersection, push one first and grab the other. Out; If the fetal head is too large, the pelvis is relatively narrow, not easy to pull out by hand, the knotted rope can be inserted into the mouth of the piglet to help pull out the chin.

If there is no piglet in the birth canal through examination, it may be that the uterine contraction is weak and the fetus is still not in the uterine horn. At this time, oxytocin can be used to promote uterine muscle contraction and help the fetus to be born as soon as possible. The injection dose is 20-30 units. I try to inject 20 units inside the labia. The effect is very good. It not only plays a role quickly, but also can save the dosage. If 30 minutes have still not worked, a second injection of oxytocin can be given. If there is still no piglet born, the sow should be driven to move around the farrowing house and the birth canal will be reset to eliminate the birthing barrier and the delivery process will proceed smoothly.
