Laminitis in horses is an inflammation and damage to the laminae within the hoof, often stemming from issues like poor diet, obesity, or inflammatory diseases. This painful condition can lead to severe complications and may even be fatal if not properly managed.
What is Laminitis?
Laminitis, commonly referred to as founder, involves inflammation and damage to the laminae—the tissues that connect the hoof wall to the coffin bone in a horse’s hoof. When these laminae become inflamed, the connection between the hoof and bone weakens, potentially causing the coffin bone to rotate or sink within the hoof.
What Causes Laminitis in Horses?
Several factors can trigger laminitis:
- Dietary Issues: Overconsumption of carbohydrates, such as grains or lush pasture, can lead to a surge in insulin levels, triggering laminitis.
- Obesity: Overweight horses are more prone to developing insulin resistance, increasing their risk of laminitis.
- Underlying Diseases: Conditions like equine metabolic syndrome (EMS) and Cushing’s disease (PPID) can disrupt hormone balance and increase the risk of laminitis.
- Inflammation: Systemic inflammation from infections or other health issues can also contribute to laminitis.
- Mechanical Stress: Excessive concussion or weight-bearing on the hooves can sometimes lead to laminitis.
How Can Laminitis Be Prevented?
Preventing laminitis involves managing risk factors and maintaining overall horse health:
- Diet Management: Control carbohydrate intake by limiting access to lush pastures and grains.
- Weight Management: Maintain a healthy weight through proper diet and exercise.
- Regular Exercise: Regular physical activity improves insulin sensitivity and overall health.
- Hoof Care: Regular trimming and shoeing can help maintain proper hoof balance and reduce stress on the laminae.
- Early Detection: Monitor horses for early signs of laminitis, such as heat in the hooves or reluctance to move.

What are the early signs of laminitis?
Early signs of laminitis include heat in the hooves, especially in the front feet, along with an increased digital pulse. Horses may also exhibit reluctance to turn or move, shifting weight between their feet to alleviate pressure. Recognizing these early indicators is crucial for prompt intervention and management.
How is laminitis diagnosed?
Veterinarians diagnose laminitis through physical examination, assessing hoof temperature, digital pulse, and stance. Radiographs (X-rays) are often used to evaluate the position of the coffin bone within the hoof and identify any rotation or sinking. These diagnostic tools help determine the severity of laminitis and guide treatment strategies.
Can laminitis be cured?
While there is no definitive cure for laminitis, its effects can be managed effectively with prompt and comprehensive treatment. Management strategies include addressing the underlying cause, providing pain relief, supporting hoof health, and making dietary adjustments. With diligent care, many horses can return to a comfortable and functional life.
What is the role of diet in managing laminitis?
Diet plays a crucial role in managing laminitis by controlling carbohydrate intake and maintaining a healthy weight. Limiting access to lush pastures and grains helps prevent insulin spikes, while providing a balanced diet with appropriate mineral and vitamin supplementation supports overall hoof health. Consulting with a veterinarian or equine nutritionist is essential for developing a tailored diet plan.
How does exercise help prevent laminitis?
Regular exercise helps prevent laminitis by improving insulin sensitivity and promoting weight management. Physical activity encourages the body to use insulin more efficiently, reducing the risk of insulin resistance, a key factor in laminitis development. Additionally, exercise helps maintain a healthy weight, further decreasing the risk of metabolic imbalances.
Understanding laminitis and taking proactive steps can significantly reduce the risk and improve the well-being of horses. By focusing on diet, weight management, and hoof care, owners can help their horses lead healthy and comfortable lives.
