Pig Rectal or Vaginal Prolapse: Emergency Signs and What to Do

Rectal prolapse happens when tissue from the rectum protrudes through the anus. In pigs, it is commonly linked to repeated straining. That straining may come from diarrhea, colitis, parasites, constipation, urinary tract problems, or weakness of the tissues that support the rectum. Merck notes that rectal prolapse due to diarrhea or weakness of rectal support tissue is one of the most common gastrointestinal problems in pigs.

Vaginal prolapse is more often seen in intact female pigs and may be associated with late pregnancy, labor problems, trauma, or hormonal influences. In breeding pigs and miniature pet pigs, dystocia can increase straining and raise the risk of reproductive tract prolapse. Feed contamination with estrogen-like mycotoxins such as zearalenone can also contribute to vulvar swelling and vaginal or rectal prolapse in swine.

Sometimes the prolapse is the visible problem, but not the root cause. Your vet may need to look for diarrhea, constipation, urinary obstruction, reproductive disease, pregnancy-related complications, or a feed issue. Treating the underlying trigger matters because prolapses often recur if the cause is not corrected.

See your vet immediately if you can see any red, pink, or tubular tissue protruding from the anus or vulva. This is especially urgent if the tissue is dark red, purple, black, dry, dirty, bleeding, foul-smelling, or larger than it was earlier. Immediate care is also needed if your pig is straining continuously, crying out, weak, not eating, pregnant, in labor, unable to pass stool, or unable to urinate.

There is very little true “watch and wait” time with a prolapse. Even tissue that looks small and pink can swell quickly and become harder to replace. A prolapse that stays out longer is more likely to become traumatized or lose blood supply.

While you are arranging care, keep your pig quiet and confined on clean bedding. Gently rinse debris off with sterile saline if available, or clean lukewarm water, and keep the tissue moist with a water-based lubricant. Do not use harsh disinfectants, sugar products, hemorrhoid creams, or human medications unless your vet specifically recommends them for your pig.

Your vet will first confirm whether the prolapse is rectal, vaginal, or from another structure, then assess how healthy the exposed tissue is. They will look for swelling, trauma, drying, contamination, and signs that the tissue has lost blood supply. Because pigs can be stressed and painful with handling, sedation is often needed for a safe exam and treatment.

In a straightforward case, your vet may clean the tissue, reduce swelling, gently replace the prolapse, and place a temporary retention suture to help keep it in place. If the tissue is badly damaged, dead, or cannot be replaced, surgery may be needed. Merck notes that severe rectal prolapse may require resection or amputation, although this can carry a risk of later stricture formation in swine.

Your vet may also recommend fecal testing, imaging, bloodwork, urinalysis, or reproductive evaluation depending on the history. Treatment often includes pain control and care directed at the cause of straining, such as diarrhea management, stool-softening strategies, urinary treatment, pregnancy support, or changing contaminated feed if a mycotoxin problem is suspected.

Home care is supportive only and should not replace veterinary treatment. While you are getting to your vet, keep the exposed tissue moist with sterile saline or a plain water-based lubricant, and keep your pig in a clean, quiet area with soft bedding. Prevent rubbing on flooring, bedding, or fencing, because even minor trauma can make the prolapse much worse.

Do not try home remedies that can irritate tissue or delay care. Avoid alcohol, peroxide, essential oils, powders, hemorrhoid products, or leftover medications. Do not feed new treats or high-fiber add-ons unless your vet recommends them, because the right plan depends on whether your pig is dealing with diarrhea, constipation, urinary straining, pregnancy, or another issue.

After treatment, follow your vet’s instructions closely. That may include medication schedules, keeping stools soft but formed, monitoring urination and bowel movements, checking the tissue or suture site daily, and returning for rechecks on time. Call your vet sooner if the prolapse reappears, the tissue changes color, your pig strains again, stops eating, seems painful, or cannot pass stool or urine.
