Colic is the single most important horse disease. It causes more horse fatalities than any other illness and even when horses fully recover it is the single biggest cause of major veterinary expenses. It can also cause other illnesses such as lminitis or founder.

There are many different types of colic and many different causes. Fortunately, the main causes have been identified by research, including studies which have covered thousands of colic cases. Following is a list of actions to avoid the main causes of colic and thereby greatly reduce the risk of your horse getting colic.

1) Frequent Feedings. Horses have evolved to graze throughout the day. The more frequently they eat, the healthier their digestive system.

2) Grass before Grain. The equine digestive system is designed for ‘high volume, low calorie’ food such as grass or hay. Energy-dense foods such as grain or musli have insufficient volume and fiber. Consequently, the diet should have as much grass or hay as possible. If one feeds both hay and grain, one should feed the hay followed by the grain rather than the reverse order, as this results in better digestion and less bolting.

3) Soak Pelleted Food. Unsoaked pellets (e.g. hay pellets) are more likely to be bolted and more likely to cause choke than soaked pellets. More relevantly, unsoaked pellets expand when they come into contact with stomach liquids and can thereby result in bloat and subsequently colic.

4) Lock Feedroom Door. Horses which get into a feedroom can stuff themselves, especially on grain, which can result in colic (it can also cause laminitis). A lock or horse-proof latch is adviseable.

5) Prevent Bolting. A horse may bolt (swallow without chewing) its food, potentially resulting in colic. This may be simply greed or a bad habit, but can also be due to medical issues such as dental problems. If your horse bolts, discuss with your vet how to correct this problem.

6) Dietary Dirt and Sand. Horses that eat dirt or sand in large amounts can develop impaction colic. Avoid putting your horses on over-grazed pastures as they are likely to eat earth when they pull up the remaining grass with attached roots. Do not feed them on a sandy or dirt surface.

6) Sufficient Water. A horse needs to drink adequate water througout the day. During winter their water should be warmed as horses often don’t drink sufficient water if it is too cold. After exercise, let them drink but limit the quantity until they have cooled down.

7) De-worming. Horses should be de-wormed regularly (every 3-4 months). All the horses which share a pasture should be de-wormed at the same time to prevent cross-infection. If a horse has not been de-wormed for a long time, use a laxative a few days before to clear out the worst of the worm population before administrating a de-wormer medication.
Regular Exercise. Horses with insufficient exercise are more prone to colic. When starting an exercise regime, start gradually as rapid changes in the amount of exercise can result in colic.

9) Eating Bedding. Many horses eat bedding, particularly straw bedding. If your horse ingests a large amount of bedding, especially inedible beddings (such as wood shavings), change to a bedding type which they don’t eat.

10) Cold. Although horses can tolerate a fair amount of cold, if they become chilled (drop in body temperature) they are likely to develop colic. This is particularly likely to occur when there is a sudden drop in temperature after a relatively mild period. Avoid these by allowing your horse to develop a winter coat and/or protecting it with a rug. Especially during wet and windy weather, the horse should be protected from excessive cold.
