Equine Metabolic Syndrome Welfare Management

Equine metabolic syndrome is a common hormonal disorder in horses and ponies causing laminitis risk and requiring lifelong management through diet and exercise.

Key Facts

Equine metabolic syndrome involves insulin dysregulation causing abnormal insulin response to sugar
Affected horses and ponies have increased laminitis risk from pasture grazing
EMS is most common in native pony breeds and cresty-necked horses and ponies
Diagnosis uses ACTH, dynamic insulin testing and assessment of body condition score and cresty neck score
Management requires strict dietary control of non-structural carbohydrates in grass and hay
Regular gentle exercise improves insulin sensitivity and contributes to weight management

Welfare Considerations

EMS welfare management requires commitment to dietary control that is often challenging for owners because it means restricting access to the natural food horses evolved to eat. Ponies with EMS that graze spring or autumn pasture face laminitis risk from high fructan content. Soaked hay removes some fermentable carbohydrates. Grazing muzzles allow some pasture access while reducing intake. The welfare goal is preventing laminitis rather than treating it - the chronic pain and potential for permanent structural damage make prevention infinitely preferable. Regular monitoring of body condition and cresty neck score enables early intervention before insulin dysregulation causes laminitis.

What You Can Do

Test horses and ponies with cresty necks or unexplained laminitis for EMS and PPID
Implement dietary management including soaked hay and restricted grazing for EMS-affected animals
Establish a management plan with vet and nutritionist for long-term EMS control
Monitor body condition and cresty neck score regularly as welfare indicators
