Equine metabolic syndrome involves insulin dysregulation and obesity that dramatically increases laminitis risk. Management to achieve healthy body condition is a primary welfare priority.
Equine metabolic syndrome is a significant welfare threat because its primary consequence, laminitis, is one of the most painful conditions horses experience. The subclinical nature of EMS means affected horses may appear healthy until a laminitis episode reveals the underlying problem. Prevention through weight management, pasture restriction, and dietary control prevents the often severe welfare consequences of repeated laminitis attacks. The management requirements for EMS horses including restricted grazing, slow feeders, and monitored diet are demanding but represent a major investment in preventing future suffering. Early identification through annual blood testing allows intervention before laminitis occurs.
