🌱 Clover Slobbers in Horses 🐴💧
Ever notice your horse drooling excessively after grazing? It might be clover slobbers!
👉 What it is:
Clover slobbers happen when horses eat clover (usually red clover) infected with a fungus called Rhizoctonia leguminicola. This fungus produces a toxin (slaframine) that stimulates salivary glands, causing lots of drool.
⚠️ The Good News:
It looks messy but usually isn’t dangerous.
Most horses stay healthy and the drooling stops once they’re off infected clover.
🩺 When to Call Your Vet:
If your horse shows other signs (colic, diarrhea, weight loss, or not eating).
If you’re unsure what’s causing the excessive drool.
💡 Prevention Tip:
Rotate pastures and avoid overgrazed areas.
Mow pastures to reduce clover dominance.
Offer hay if pasture conditions are poor.
