Large Colon

After exiting the cecum, the digesta enters the 10-12 foot long large colon for absorption of the bacteria produced nutrients formed in the cecum. Problems within the large intestine are the most common cause of colic in the horse. Signs of colic include: kicking at their abdomen, rolling, and a poor appetite. Colic requires immediate veterinary attention. Disorders causing large intestinal pain include: sudden diet changes (i.e.: grain excess), impactions from food (often related to poor dental health), enteroliths, displacements, infections (e.g.: Salmonella), Blister beetle toxicity, and parasites (e.g.: Strongyles).
