What clinical finding is characteristic of rectal strictures in pigs?

  1. Acute diarrhea

  2. Weight loss

  3. Ulcerative proctitis

  4. Persistent vomiting

The correct answer is: Ulcerative proctitis

Rectal strictures in pigs typically lead to significant alterations in bowel function, and ulcerative proctitis is one of the characteristic clinical findings associated with this condition. Strictures can create a narrow passage in the rectum, which can lead to inflammation and ulceration of the rectal mucosa. This occurs due to increased pressure associated with attempting to pass feces through a narrowed area, resulting in trauma and subsequent lesions that manifest as ulcerative proctitis. The presence of ulcerative lesions indicates significant irritation and damage to the mucosal layer, which is a direct consequence of the obstructive nature of strictures. Pigs with rectal strictures are likely to show signs of discomfort and may exhibit abnormal fecal production or defecation behavior, reinforcing the association of strictures with inflammatory lesions such as ulcerative proctitis. Other options, while potentially relevant in broader gastrointestinal issues, do not specifically characterize the presence of rectal strictures in pigs. For example, acute diarrhea might suggest a different gastrointestinal disorder, and while weight loss can occur with a variety of chronic conditions, it is not specific to rectal strictures. Persistent vomiting is also not typically associated with rectal strictures in pigs, as vomiting is less common in
