Horse Equine Metabolic Syndrome and Welfare

Equine metabolic syndrome (EMS) and its associated risk of laminitis cause significant welfare suffering in overweight horses and ponies, requiring dietary management and exercise.

Key Facts

EMS involves insulin dysregulation leading to chronic laminitis in overweight equines
Native pony breeds are genetically adapted to sparse grazing and are most vulnerable
Laminitis causes chronic severe pain affecting mobility and quality of life
Strip grazing and restricted pasture access are key management strategies
Weight loss through diet and exercise is the primary treatment

Welfare Considerations

EMS and laminitis welfare requires strict dietary management that is often resisted by owners who anthropomorphise horses' enjoyment of grazing. The welfare cost of laminitis is severe and long-term. Preventive management is far better for welfare than treating repeated laminitis episodes.

What You Can Do

Assess your horse or pony's body condition score regularly and manage weight proactively
Restrict pasture access for overweight equines and use appropriate diet management
Seek veterinary assessment if your horse shows any signs of foot pain or laminitis
