Sow dystocia does not naturally produce the fetus when it is delivered. The occurrence of dystocia is caused by too thin sows, but also due to lack of exercise and physical deficiencies. Feeding before meals, satiety constipation, rectal fecal compression of the birth canal can also cause sows to give birth. Sows are required to implement midwifery immediately after delivery, ensuring safe sows and piglets. First, the symptoms The sow is pregnant and has reached the end of her gestational period. There is a phenomenon of childbirth, but it does not produce piglets. Due to childbirth and difficult labor, the number of performances is low and the strength is weak. The childbirth can not be produced for a long time after the start of childbirth. Due to dystocia caused by fetal abnormalities, the birth canal opening condition and the delivery force are normal, but the production of piglets is not seen. Because of the narrow birth canal production, the performance of the vulva is not enough to open and relax, and the delivery force is normal, but only some fetal water is discharged and it cannot be produced. If the labor is too long and the treatment is not proper, the sow will be weak, the heartbeat will be weakened, the breath will be slight, and the serious sow will die in 2-3 days. Second, prevention Pay attention to the selection and matching to avoid inbreeding. Sows must be mated after 10 months of age. Pay attention to proper movement and feeding of appropriate amount of green feed and mineral feed to pregnant sows, and a reasonable mix of feeds to prevent sows from becoming overweight and wasted. When the sow comes into production, it must be guarded by a special person so that it can be discovered as soon as possible when dystocia occurs and promptly treated. Third, treatment 1, after sow fetal water discharge, repeatedly forced to shrank, still not seen fetal discharge is dystocia. At this time injectable oxytocin, the amount of 2 ml per 100 kg, intramuscular injection. 20-30 minutes after the general injection, piglets can be produced. 2. For frail elderly sows, firstly, each sow should be injected intramuscularly with 10-30 units of posterior pituitrin to promote uterine contraction and piglet output. If the fetus is still not producing 30 minutes after intramuscular injection of pituitrin, the midwifery can put their hand into the sow's birth canal, massage the cervix, and slowly pull the fetus out as the sow shrinks. 3. For sows whose sow's amniotic fluid is discharged prematurely, the birth canal is narrow and dry, and the foetus is too large, etc., sows can be injected into the sow's birth canal with clean oil lubricants, and then the midwife can put their hands into the birth canal. As the sow shrank, slowly pull the baby out. 4. For sows with abnormal fetal position that cause dystocia, midwifery personnel can put their hands into the birth canal and push them into the hindlimb or forelimb of the fetus to remove the fetus. If the sow's birth canal is dry, clean lubricant can be injected into the birth canal during midwifery. If it is not possible to correct the fetal position and it is not possible or appropriate to perform caesarean section, some parts of the fetus can be removed.
