Prolapse of rectum in pigs can not recover how to prevent and cure prolapse of anus in pigs

Porcine prolapse of the anus means that the mucous membrane or part of the rectum protrudes out of the anus and can not be recovered automatically, which is characterized by the prolapse of the end of the large intestine and the medial part of the anus. The causes of pig prolapse of anus are very complicated, generally speaking, there are the following:

pig

1. Feed problem. Sudden feed change, feed deterioration or mildew, low crude fiber content, too much roughage, high calcium content and so on will cause prolapse of the anus.

2. Management problems. The breeding density is high, the pig house is cold, the temperature difference between day and night is big, the pig herds gather together, such as pig cough, it is easy to suffer from the disease. Sow delivery, high-density transport, resulting in increased abdominal pressure, and prolapse of the anus. Too high temperature, sudden weather, and a variety of stress factors in feeding, such as biting, running, strenuous exercise, will also cause pig anus prolapse.

3. Disease. Some diseases can cause severe inflammation, long-term constipation and intractable dysentery in pigs. Respiratory disease with severe cough can cause an increase in abdominal pressure, resulting in prolapse of the anus.

4. Drug problems. When lincomycin or tylosin in feed exceeds the standard, it will lead to swelling of the edge of the rectum, followed by prolapse of the anus; in addition, long-term consumption of some antibiotics will cause intestinal flora imbalance of pigs to form constipation and lead to prolapse of the anus.

5. Genetic problems. Prolapse of the anus is related to heredity, inbreeding, so that genetic defects are shown, the incidence of the disease increases.

6. Urethritis, vaginitis, rectal or urethral injury after mating and excessive salt in diet can also cause prolapse of anus in pigs.

Prevention and control measures:

1. Feed high-quality full-price materials, supplement green feed at the same time, provide adequate clean drinking water, maintain proper exercise and prevent feed mildew.

2. Strengthen feeding and management, prevent shock, reduce all kinds of stress, carry it lightly when changing groups, keep warm in winter, and prevent inbreeding.

3. Treatment. First, the symptoms are mild, the exfoliated intestines are washed with warm 10% alum or potassium permanganate water, then lift the hind legs of the pig, slowly send them back to the abdominal cavity, and inject 95% alcohol at the upper and lower anus at four o'clock, each point 2-3ml, so that the pig is driven off the ground, Baoding 20: 30 minutes, after the rectum irritation gradually alleviated, Nucht disappeared, put into a single circle, isolated breeding. Second, serious prolapse of the anus, surgical treatment: purse suture. When suturing, first use disinfectant to clean and disinfect the needle, thread, scissors, surgical utensils, arms and the detached parts, and gently squeeze out the edema with your hands, such as ulceration, peel off rotten meat, clean it, then gently send it into the anus, and then suture. After the operation, rice and penicillin are injected into Houhai acupoint, used continuously for 2-3 times, isolated and raised, and generally returned to normal within 3 days.

4. Prolapse of anus is easy to relapse. Pigs with prolapse of anus more than 2 times have no feeding value. It is necessary to eliminate the treatment, and sows with prolapse of anus should not continue to breed.
