As we step into 2025, lower temperatures and snowfall have swept across many parts of the UK and Ireland. With changes in weather come changes in horse management, which, as many horse owners know, can increase the risk of colic. One of the most common types of colic during this time of year is impaction colic.

What Is Impaction Colic?

Impaction colic occurs when there is a blockage in the digestive tract, often at the pelvic flexure—a hairpin bend in the horse's digestive system where the colon's diameter narrows significantly. This blockage can arise if the diet is particularly dry or if feed particles are larger than usual. The impacted material begins to dehydrate, making it difficult for the horse to pass, ultimately obstructing the passage of food and causing discomfort.

Why Does Winter Increase the Risk?

Winter weather often leads to changes in horse management routines, which can increase the risk of impaction colic. Common contributing factors include:

  • Restricted exercise or turnout:Horses may be confined due to icy or snowy conditions.

  • Reduced water intake:Horses are less inclined to drink in cold weather, and freezing temperatures can lead to frozen water sources, limiting access to clean drinking water.

Signs of Impaction Colic

Look out for the following signs of impaction colic:

  • Fewer or smaller droppings

  • Very dry droppings

  • Reduced appetite

  • Pawing at the ground

  • Rolling or restlessness

  • Lying down more frequently

If you suspect your horse may have colic, contact your vet immediately.

How to Reduce the Risk of Impaction Colic

Here are some practical steps to help prevent impaction colic during colder months:

  1. Provide fresh, clean drinking water at all times. Consider floating a ball in water buckets to help prevent freezing.

  2. Encourage hydration. Feed sloppy mashes or wet feeds to increase water intake and stimulate gut motility.

  3. Maintain regular exercise.If it's safe, even a short hand-walk is better than no movement at all.

  4. Offer smaller, more frequent meals.This can help maintain consistent digestion.

  5. Provide ample forage.Ensure your horse always has access to hay or haylage.

  6. Stay up to date with worming and dental care.Poor dental health or worm burdens can exacerbate colic risks.

  7. Monitor droppings closely.Changes in droppings can be an early warning sign of digestive issues.
