Pig farmers know that a pig farm wants to make money, and the most important thing is that the sow is calving. However, in the process of calving in sows, it is easy to have slow, difficult births, etc., sows can not be produced normally. If it is not handled well, it will easily lead to the death of sows and piglets. All pig farmers must master the correct methods and precautions. Let's take a look at the Xiaonong.com.
First, midwifery methods
1, normal position
First, gently extend the hand into the sow's birth canal. When touching the piglet, gently hook one finger to the hind leg of the piglet. The other fingers are pushed inside to push the pig's buttocks, and then pull the piglet's hind leg. Out, return the piglets to their normal position, and then pull the piglets out of the uterus.
2, the head in the mouth
The forefinger can be inserted into the mouth of the piglet to the canine's teeth, the thumb is pinched outside, and the piglet is pulled out.
3, two at the same time
The abdomen of both piglets is squeezed into the birth canal, and the forward position and the reverse position can be used. In this case, one piglet can be grasped and pulled out, and then the second piglet is pulled.
4, the first out of the back
The back of the piglet is stuck in front of the pelvis and is a difficult position to correct. Especially when the sow's birth canal is small and the piglet is large, the normal position can be used. The pig can be pushed inside, then Pull the hind legs of the piglets and pull the hind legs into the birth canal. However, if this method cannot be solved, only caesarean section can be performed.
5, the uterus is too heavy
If the sow has more than 14 litters, it may compress the uterus and fall under the pelvic cavity. At this time, the uterus will form the shape of S. In this case, the first piglet can be used for midwifery. After the S shape is restored and straightened, the normal position can be used for midwifery.
Second, the matters needing attention
1. The action should be gentle during the midwifery, and the lubricant should be used. It needs to be hygienic and disinfected. You can wash your hands and arms with warm water and sterilizing soap, put on disinfectant gloves, and clean the sow's production door.
2. In special cases, you need to use the device to assist the childbirth, but pay special attention to it. If the piglet still has signs of life, try not to use this method. The device will hurt or tear the piglet. It needs to be very patient and not too hard. It is easy to damage the birth canal of the sow.
3. The instruments that can be used include obstetric forceps and half-moon forceps. You can also lock the pig's head or dog's teeth with a rope cover. The rope cover is not easy to damage the sow's birth canal, so it is a better choice.
The above is the method of midwifery and the precautions for sows. Under normal circumstances, sows do not need midwifery. However, if the sow is found to have prenatal symptoms, such as circular, irritability, milking, anger, etc., and has not been calving for 1-2 hours, or 1-2 hours after giving birth, there is no calving. If you need artificial birth support. The pig farmers have mastered the above methods and precautions to avoid unnecessary losses.
