Equine Metabolic Syndrome and Welfare

Equine Metabolic Syndrome causes chronic laminitis - a painful hoof condition - in affected horses, requiring lifelong dietary management to prevent acute flare-ups and maintain quality of life.

Key Facts

Equine Metabolic Syndrome affects an estimated 20% of horses and ponies in some populations
The condition involves insulin dysregulation that predisposes horses to laminitis following grass consumption
Laminitis is one of the most painful conditions in horses, ranking alongside colic in severity
Native pony breeds including Welsh, Dartmoor, and New Forest are particularly susceptible
Management requires strict dietary control, restricted grazing, and sometimes medication

Welfare Considerations

Equine Metabolic Syndrome welfare illustrates the challenge of managing chronic disease in animals that cannot understand why their environment must be restricted. Horses with EMS that are allowed unrestricted grazing develop laminitis - a condition where inflammation within the hoof capsule causes severe pain with each step. In severe cases horses lie down unable to bear weight. Dietary restriction through strip grazing, muzzles, or complete removal from pasture prevents laminitis but requires significant management. The welfare of horses in chronic laminitis is severely compromised, and appropriate management including pain relief and farriery support is essential. Early diagnosis and consistent management prevent most acute episodes.

What You Can Do

Have horses and ponies tested for insulin dysregulation if they show signs of laminitis
Work with your vet and farrier to develop a management plan for horses with EMS
Implement appropriate grazing restriction during high-risk spring and autumn periods
Monitor body condition score regularly in native breed ponies prone to EMS
