Horse Metabolic Syndrome Welfare

Equine Metabolic Syndrome (EMS) predisposes horses and ponies to laminitis; dietary and management interventions are central to welfare outcomes.

Key Facts

EMS is characterised by insulin dysregulation, regional adiposity, and predisposition to pasture-associated laminitis.
Laminitis is one of the most painful conditions affecting horses, with severe cases leading to euthanasia.
Native breeds such as Welsh, Dartmoor, and Shetland ponies are disproportionately affected.
Dietary management — restricting non-structural carbohydrates — is the primary intervention.
Exercise improves insulin sensitivity; even light daily exercise benefits EMS horses when laminitis is not active.

Welfare Considerations

Horses and ponies with EMS face a lifelong risk of laminitis episodes, which cause severe pain in the hooves and can become chronic. The welfare impact is substantial: animals may spend weeks or months on box rest, require intensive pain management, and face repeat episodes. Prevention through dietary restriction — particularly limiting access to lush spring and autumn pasture — is critical. Owners often find restriction difficult to implement due to emotional challenges; veterinary and nutritional support helps compliance. Regular farriery and radiographic monitoring of pedal bone position improve outcomes.

What You Can Do

Have overweight or cresty-necked horses and ponies tested for insulin dysregulation annually.
Implement grazing muzzles and track systems for at-risk animals during high-risk pasture seasons.
Work with an equine nutritionist to formulate low-NSC diets that meet all requirements.
Learn to recognise early signs of laminitis and seek veterinary help immediately.
