Colic refers to abdominal pain in horses. With many possible causes, colic is often unpredictable and hard to prevent. The risk of colic in horses often increases with sudden changes in management. As you provide winter care, think about how you can help your horse ease into changes. Here are a few suggestions.
💦 Make sure your horse stays hydrated. Cold weather can reduce your horse’s water intake and increase the risk of colic, especially since we rely on drier, preserved feedstuffs (like hay). Always provide free access to fresh, clean water. Horses prefer water between 45°F and 65°F. Soaking feed can also help boost hydration if needed. Remember, snow and ice are not appropriate water sources.
⏰ When changing feed, gradually do so over 10 to 14 days. Similarly, if you mainly feed grass hay but have a few alfalfa bales, replace only a small amount of grass hay with alfalfa every other meal until it's fed out. Gradual changes allow your horse’s gut microbes time to adjust.
🌾 Maximize your horse's forage intake to support gut health, provide energy, promote heat production, and satisfy their natural grazing instincts. Horses should have 1.5 to 2 percent of their body weight in forage daily. Access to forage for at least 14.5 hours a day can support proper digestion and overall behavior. To extend eating time, offer smaller, frequent meals or use slow feeders like hay nets.
🐎 Maintain an exercise and/or turnout routine. Activity supports gut health in horses. If you need to adjust exercise time/intensity or length of turnout for winter, make these changes slowly. Many healthy horses do well with turnout during cold weather if they have access to shelter, hay, and water. Keeping horses moving and reducing sudden changes in housing routine (e.g., full turnout to full stall), when possible, can reduce the risk of colic.
