Types of Colic 1. Any number of foreign objects that are ingested by the horse, which can cause the intestines to become blocked, can cause colic. Shavings, rubber, wire and bits of wood have all been discovered in colic related fatalities. Gas Colic Lush green feeds such as alfalfa rapidly ferment and can cause a gas buildup in the large intestine resulting in reduced motility and pain. Intestinal Spasms Can be caused by excitement, excessively cold water, moldy feed or sudden changes in feed.
Parasites Can cause a blockage or in some cases restrict blood flow to the intestines.
None of us wants to see our horses suffer from colic even in its milder forms, so we should do what we can to prevent it from occurring. Some of these management practices may help to reduce the risks. Feed grain in small amounts and over several feedings. If possible, feed no more than 5 pounds of grain per feeding. Avoid dusty or moldy grain.
