1. Some vaginal prolapse can retract when standing, generally without reduction and fixation. Nutrition should be strengthened, lying on the ground should be reduced, and sows should be forced to be low before and high after, so as to reduce abdominal pressure and achieve the purpose of self-healing. When standing can't retract itself, it should be reduced and fixed, combined with drug treatment. The traditional Chinese medicine prescription of "tonifying deficiency and benefiting qi" can generally be cured.

2. Complete vaginal prolapse should be reduced and fixed, combined with drug treatment. In Baoding, keep the pig in the posture of front low and then high, wrap its tail and pull it to its side, remove necrotic tissue, and thoroughly clean the part and its surroundings with 2% alum solution, 0. 1% potassium permanganate solution and 0. 1% nifedipine solution. When edema is severe, hot compress, kneading or scratching will make edema fluid flow out. Then cover the vagina with sterilized gauze or fine gauze coated with antibiotics, feed the vagina with the palm of your hand when the pig is not responsible, then take out the gauze, take the acupoint for treating prolapse (lcm is opened near the midpoint of the labia) and the Houhai acupoint for electroacupuncture, or inject 30-40 ml of 70% alcohol into submucosal cellula on both sides of the labia, or fix it with a grid vulva bracket or rope net, or close the vulva with sterile thick suture. When the pig's excessive force affects the reduction and fixation, epidural anesthesia or sacral canal closure can be done. Strengthen feeding management, feed rich and digestible feed, and the diet should contain enough protein, inorganic salts and vitamins to prevent constipation; Don't overeat to relieve abdominal pressure. Let sows exercise properly to enhance muscle contraction.
