Winter Gut Check: Colic, Stress, and Stabling Changes That Can Knock Digestion Off Track

Winter does not just change your horse’s coat and workload. It changes the entire digestive environment.

Less turnout, less movement, colder water, more time on dry forage, and routine disruption can all chip away at gut stability. Many vets and equine welfare organisations flag winter management changes as a key risk period for digestive disruption, including impaction-type colic. 

This guide covers:

• why winter can be a gut “wobble” season

• the 5 biggest triggers

• a daily gut-friendly routine

• how to change forage and feed safely

• signs you should not ignore

And yes, we’ll also talk about a simple “toolkit” approach that supports comfort and consistency through the season.

Why winter increases digestive disruption

Colic is a broad term for abdominal pain and it can range from mild to life-threatening, which is why winter gut management is worth taking seriously. 

In winter, a few common changes stack up:

• Less movement and turnout (gut motility matters) 

• Reduced water intake (especially if water is cold or partially frozen) 

• More dry forage, less grass (higher fibre load needs good hydration)

• Routine disruption (stabling changes, different feeding times, different forage sources) 

None of this means colic is inevitable. It just means winter is a season where consistency and small daily habits do a lot of heavy lifting.

The 5 biggest winter triggers (and what to do about each)

1) Drinking less than normal

Cold water, frozen troughs, and reduced thirst cues can all mean horses drink less in winter, increasing dehydration risk which is associated with impaction colic. 

What helps:

• Check water sources multiple times a day in freezing weather

• Offer an additional bucket and keep it fresh

• If your horse is fussy, try slightly warmed water (lukewarm, not hot) 

• Add moisture to feeds when appropriate (see the daily routine section)

2) More stabling, less movement

Reduced movement is repeatedly referenced as a winter risk factor for impaction colic. 

What helps:

• Keep movement “little and often” where you can: in-hand walking, turnout windows, more frequent ridden sessions (even if lighter)

• Avoid long periods of complete inactivity where possible

3) Sudden changes to forage or feed

Dietary change is one of the biggest controllable risk factors. The risk of colic is often highlighted as highest in the two weeks following dietary changes, including forage changes.

What helps:

• Change forage gradually over 10 to 14 days where you can

• If you have to swap forage quickly (supply issues happen), do everything else to support stability: hydration, consistent routine, and careful monitoring

4) “Feeding around the weather”

This is a classic winter pattern: less grazing, more hay, sometimes more hard feed, and occasional “make-up meals” when turnout is limited.

What helps:

• Keep forage consistent and available

• If concentrates need to increase, do it slowly and only if genuinely needed

• Avoid big meal sizes. Smaller, more frequent feeds are generally kinder to the gut

5) Stress and routine disruption

Horses are sensitive to routine. Stabling changes, reduced social contact, increased time indoors, and changes in exercise can increase stress behaviours and impact gut stability. Welfare guidance highlights routine changes, reduced movement, and diet changes as factors that can increase colic risk. 

What helps:

• Maintain predictable feeding times

• Keep forage available

• Provide enrichment in the stable (slow feeders, stable toys, forage variety if suitable)

• Maximise social contact where safely possible

A simple daily “gut-friendly” winter routine

This is the kind of routine that is realistic for busy yards and actually makes a difference because it is consistent.

Daily gut checklist (2 minutes)

• Water check: is it clean, unfrozen, and is your horse actually drinking?

• Droppings check: any change in frequency, consistency, smell, or dryness?

• Appetite check: leaving forage, picking at feed, slower eating?

• Behaviour check: flank watching, pawing, restless, dull, stretching, lying down more than normal? 

Daily support habits

• Keep forage steady and avoid long gaps without fibre

• Consider adding moisture to feeds when appropriate (especially if on dry hay and drinking less)

• Movement where possible, even if it is gentle

How to change forage and feed safely (without upsetting the gut)

If there is one winter rule that is worth repeating: change slowly.

Practical approach:

1. Introduce the new forage in small amounts alongside the current forage

2. Increase the proportion gradually over 10 to 14 days

3. Watch droppings and behaviour through the transition

4. Keep everything else stable during the change (routine, turnout, work) where possible

If you are changing hard feed, follow the same principle. Consistency is the aim.

Signs you should not ignore

Colic can escalate quickly. If you are concerned, call your vet.

Common warning signs include:

• Pawing, looking at the flank, rolling, repeated lying down and getting up.

• Reduced appetite or refusing feed

• Fewer droppings or very dry droppings

• Dullness, sweating, increased heart rate, signs of pain 

If you are in any doubt, treat it as urgent. Early intervention matters. 

A simple winter “toolkit” approach

The goal in winter is not to react to a crisis. It is to keep the gut steady.

Radiance Gold Original (for daily consistency)

Radiance Gold Original is positioned as a daily digestive support supplement, described as promoting balanced gut flora and supporting digestion and immune health.

If your horse is prone to winter wobbles, it can be helpful to keep the daily routine consistent rather than chopping and changing multiple things at once.

Activated charcoal (as an occasional comfort tool)

Radiance Gold Premium Charcoal is described as a coconut-shell, steam-activated charcoal supplement and is marketed for binding and reducing intestinal gas to support digestive comfort. 

A sensible note here: activated charcoal is commonly discussed in relation to gas and toxins, but the evidence base is mixed and veterinary use is typically most relevant when toxin ingestion is suspected. If you are worried about colic, toxicity, or serious symptoms, speak to your vet first.
