1, lift the pig's hind legs and hang them with ropes, which can be tied to the door frame or shed roof for protection. In mild cases, wash the prolapsed intestine with warm 0. 1% potassium permanganate water or warm water with appropriate disinfectant, then slowly send it back to the abdominal cavity, and inject 95% alcohol into four points of anus, 2 ~ 3 ml each. After about half an hour, the bad stimulation of rectum gradually eased and the sense of responsibility disappeared. Put the pig down and raise it in isolation, but it is easy to repeat. I often use surgical suture more thoroughly. 2. The pig with severe proctoptosis should be surgically sutured. When sewing, the needle, thread, scissors and the part coming out of anus should be cleaned and disinfected with disinfectant. Then use the index finger and thumb to remove the mucosa that has fallen off from the edema, and the rectum will automatically retract into the anus and then suture. The method of suture is to sew directly with thread in the middle, make a knot suture, and sew another needle on one side at most. There was no isolation and no feeding after the operation. Recently, several cases were cured by the author's continuous program. 3. After the operation, rice and penicillin are injected into Houhai point (Houhai point is above the anus of the pig and at the middle fossa below the tail root) for 2 ~ 3 times, and it will return to normal in 3 ~ 5 days. Most of them don't need anti-inflammation, and they can also be directly injected with anti-inflammatory drugs. ]
