Equine Metabolic Syndrome and Laminitis Welfare

Equine Metabolic Syndrome (EMS) and the associated risk of laminitis represent a major welfare challenge in horses and ponies, causing chronic and acute pain that is often inadequately managed.

Key Facts

Laminitis is inflammation of the sensitive laminae within the hoof, causing severe pain - sometimes described as equivalent to nails driven into the fingertips
EMS, like type 2 diabetes in humans, involves insulin dysregulation and increased laminitis risk from simple sugars in grass
Native pony breeds are genetically predisposed to EMS as an adaptation to poor mountain pasture
Acute laminitis crises cause intense pain requiring urgent veterinary treatment and pain management
Chronic laminitis causes long-term structural hoof changes (rotation, sinking) that cause ongoing welfare suffering
Dietary management through grazing restriction, soaked hay, and careful pasture management is the primary prevention strategy

Welfare Considerations

Laminitis is one of the most serious and common welfare problems in horses and ponies, and EMS is its most significant preventable cause. The welfare burden is substantial: acute episodes involve intense pain, and chronic cases involve persistent discomfort with every step. Early recognition of EMS risk, dietary management, and veterinary guidance can prevent many cases. However, management of an easy-keeper native pony on spring grass requires constant vigilance and restriction that can be emotionally challenging for owners. The key welfare principle is that restriction of grazing, while appearing unkind, prevents significantly greater suffering. Veterinary pain management and farriery input are essential in acute and chronic cases.

What You Can Do

Learn to recognise EMS risk factors: cresty neck, weight gain on sparse pasture, prior laminitis history
Implement dietary management with your vet before laminitis crisis occurs
Seek immediate veterinary attention for any horse or pony showing laminitis signs: heat in feet, reluctant movement
