Dystocia is one of the problems that many farmers have headaches and encounters. When the sow is too old or too small, the body is too fat or too thin, the birth canal is narrow, the fetal position is not correct, and the fetus is serious, it will produce dystocia. Let's take a look at the causes and disposal methods of dystocia in sows. 1 Common causes of dystocia in sows 1.1 Reasons for sows 1.1.1 Age and body condition Too old or too young, too fat or too thin. Older sows have a long service life, because of the production, they often cause physical weakness, poor uterine contractility; sows with too much fat or too thin body, poor uterine contractility, and difficult fetal delivery; and too small sows, especially It is a primiparous sow. Even if the sow has a strong uterine contraction force, the fetus is still difficult to deliver because of the narrow birth canal and small pelvic ostium. 1.1.2 Too much urine in the bladder More common in the sow's weakness, disease and other causes of bladder paralysis. At this time, the urine can not be discharged in time, the bladder accumulates a large amount of urine, and the birth canal is squeezed by the bladder and causes dystocia. 1.1.3 External stimulus There are abnormal irritations in the delivery room. If the environment is not quiet, the light is too strong, the odor is too strong, etc., the sows will have great stress on the primiparous or timid sows, the sows will be restless, and the uterus will not be normal rhythm. Sexual contraction causes dystocia. 1.1.4 Sow sick The sows with various diseases, especially febrile infections, congenital genital tract abnormalities such as birth canal malformations, can cause dystocia. 1.2 Reasons for the fetus The number of litters in the sow is small, the fetus is over-developed; the fetal position is not correct, the fetal posture is not correct in the birth canal; the fetal malformation; the fetus has been in the mother for a long time, the fetal corpse has edema and bloating in the mother; the fetal weight is too small, Both fetuses entering the birth canal at the same time, etc., can cause sows to be difficult to produce. 1.3 Reasons for man-made Oxytocin is used prematurely during oxytocin. The operation method is not standardized when the artificial midwifery is used. If the amount of lubricant in the birth canal is too small, the birth canal is not dry, and it can cause dystocia. 2 clinical manifestations of dystocia in sows Difficult to produce sows caused by different reasons, often have different clinical manifestations. Most dystocia sows show loss of appetite or lack of food, painful sputum, restlessness, blame, swelling of the vulva from time to time, but no piglets are delivered; sows are swollen and some can squeeze milk. If the duration is too long, it will easily cause stillbirth, and even cause death of sows. There are also some sows. After the normal delivery of 1~2 piglets, no more piglets are produced at intervals of 0.5~1h. Pregnant sows who have had a dead child for a long time have been spoiled or become mummified in the sow. It tends to prolong the gestation period, and there is no sign of childbirth after more than 116 days, but sometimes it is visible that the filth from the vagina. 3 Disposal methods for sow dystocia 3.1 Drug oxytocin If the sows have a history of dystocia before, they can use intramuscular injection of cloprostenol 2 (0.2 mg each) at 12:00 noon on the 1st day before the expected date of delivery, and normal delivery at 8 to 12 noon on the 2nd day. For sows that have no signs of childbirth during pregnancy or more than the expected date of delivery and have died of stillbirth, 2 intramuscular injections of cloprostenol can also be administered intramuscularly to discharge the stillbirth in time to save the sow. 3.2 Artificial midwifery Artificial sows must be given to sows who are ineffective in using medicinal products or sows that are dystocia due to other factors. Common methods are: 3.2.1 Rescue movement For sows with good physical condition and still able to move, in the event of dystocia, the sows can be driven out and driven out in the abdomen of the birthing house. Sometimes it is effective for those dystocia that are not due to fetal position. 3.2.2 Massage For the sows who can't stand and move, they can be artificially massaged: the five fingers are close together, straightened, close to the sow's chest, from front to back, massage the sow's breast area and side abdomen to strengthen the sow's efforts , successfully delivered the fetus. 3.2.3 Pressing If the sow is constantly responsible, but no piglets are delivered, the midwife can hold the railing of the bed with both hands, and vacant the feet, press on the side of the sow, and do not press hard. Following the sow's blame, try to help the sow to deliver the fetus from front to back. Note: Surgical treatment is required when the fetus cannot be discharged by the above conservative methods. The above is all about the sow's dystocia. If you encounter this situation, you can try these methods. I hope that everyone can help!
