Which of the following is NOT a symptom of colic?

Coughing is not typically associated with colic in horses. Colic generally refers to any pain in the abdomen, often related to issues with the digestive system. The primary symptoms of colic usually include behaviors directly associated with discomfort in the abdomen, such as rolling, restlessness, or looking at their sides (which indicates the horse's awareness of abdominal pain).

When a horse exhibits signs of colic, the animal may roll on the ground, a behavior that can indicate severe pain or discomfort. Restlessness is another common symptom, as the horse may move around continuously, trying to find relief from the pain. Looking at the abdomen or trying to kick at their belly also suggests that the horse is feeling discomfort in that area.

Coughing, on the other hand, often signals respiratory issues rather than gastrointestinal problems. While coughing can be a symptom of other conditions, it does not indicate colic and is not a behavior you would expect to see in a horse experiencing colic.
