Which of the following digestive tract diseases most commonly affects horses?

Colic is the most common digestive tract disease affecting horses, and this is largely due to their unique digestive physiology and feeding habits. Horses have a single-chambered stomach and a long, complex intestinal tract, which makes them susceptible to a variety of gastrointestinal issues.

Colic primarily refers to abdominal pain, which can arise from several underlying causes, such as intestinal blockages, gas buildup, or twisted intestines. The horse's grazing habits can lead to the consumption of foreign objects, excessive amounts of feed, or even sudden changes in diet, all of which can trigger colic.

The other options, while certainly relevant in discussions of equine health, do not have the same prevalence or recognition as colic in the equine population. Enteritis, an inflammation of the intestine, is less common than colic and often presents in acute phases rather than as a chronic issue. Acidosis, related to an imbalance in nutrient absorption and pH levels, can occur but is not as frequently diagnosed specifically in horses compared to other species. Constipation is also a concern but is not seen with the same frequency or severity as colic.
