Rectal Stricture

This is a condition often considered a sequel to rectal prolapse in growers and finishers. Approximately a fingers length inside the rectum the tissues gradually shrink, scar tissue develops and eventually the tube completely closes. The area where the stricture occurs is supplied by two tiny arteries that originate from the aorta. Some studies suggest that if these arteries are blocked or thrombosed by bacteria a rectal stricture will result. Erysipelas, Haemophilus parasuis, streptococci and salmonella have been implicated.
