In Times of Viral Threat, Gut Health Isn’t Optional — It’s Everything 🐴🧬
With the recent EHV-1 outbreak on everyone’s radar, let’s talk about something that often gets overlooked in moments like this: the gut.
Your horse’s digestive system isn’t just for processing hay — it’s home to 70% of their immune system. When the gut is out of balance, the immune system has to work harder. That’s a problem during any viral outbreak.
And unfortunately, a lot of modern horse care makes gut health harder to maintain.
🚨 What Today’s Management Practices Do to the Gut
Let’s be honest — most of what we ask from our horses isn’t “natural”:
❌ High-grain diets disrupt the microbial balance in the hindgut, leading to inflammation, leaky gut, and lowered immunity.
❌ Frequent travel and competition add physical and psychological stress, which directly impacts digestion, hydration, and immune readiness.
❌ Pharmaceuticals (like NSAIDs and ulcer meds) have their place — but they can also disrupt the gut lining and microbiota over time.
❌ Limited turnout and irregular forage access mean the gut isn’t getting what it evolved to need: constant, slow fermentation of fiber.
In short: even the best-cared-for performance horse may be walking a fine line when it comes to immune health — especially during an outbreak.
🌿 So What Can You Do? Focus on the Gut.
✅ Prioritize Forage.
Consistent, clean hay and access to forage throughout the day help maintain a healthy hindgut and stable energy — far more than grain ever could.
✅ Reduce or eliminate excess starch.
Low-starch, forage-first feeding keeps the microbial balance in check and inflammation down — which is crucial when the immune system is under pressure.
✅ Be mindful with medications.
Work with your vet to use meds strategically and support the gut before, during, and after treatment. The gut lining needs time and nutrition to heal.
✅ Keep stress low where you can.
Routine, turnout, and herd interaction all support gut motility and calm the nervous system — both of which are tied directly to digestion and immunity.
✅ Watch for silent signs.
Not all gut stress looks like colic. Loose manure, girthiness, dull coat, irritability, or even underperformance can signal something’s off in the digestive tract.
📣 Bottom Line:
We can’t control every risk, but we can control how we feed and manage our horses.
In times like these, gut health is immune health. It’s not about gimmicks — it’s about giving the body what it needs to do its job.
Feed fiber. Avoid unnecessary starch. Watch the stress. Support the system.
💚 Your horse’s gut (and immune system) will thank you.
