Laminitis, or founder, is the inflammation of the laminae in a hoof, often caused by a poor diet, obesity, or other inflammatory diseases, leading to extreme pain and potential fatality. While no specific feed directly causes laminitis, certain feeds and feeding practices can increase the risk. Feeds high in sugars and starches, such as cereal grains and by-products from sugar processing, should be avoided or carefully managed.
Understanding Laminitis and Its Causes
Laminitis is a debilitating condition affecting the hooves of animals, particularly horses and cows. It involves inflammation and damage to the laminae, the sensitive tissues that attach the hoof wall to the coffin bone. This can cause severe pain, lameness, and, in severe cases, the coffin bone can rotate or sink within the hoof, leading to chronic lameness or the need for euthanasia.
What Dietary Factors Contribute to Laminitis?
Several dietary factors can increase the risk of laminitis:
- High-Sugar and Starch Feeds: Feeds rich in simple sugars and starches, such as cereal grains (corn, barley, wheat) and their by-products, can cause a rapid increase in blood glucose and insulin levels. This can disrupt the hindgut microbiome and trigger inflammation, increasing the risk of laminitis.
- Pasture Grasses: Lush pastures, especially in spring and fall, can be high in fructans, a type of sugar that some animals cannot digest efficiently.
- By-products of Sugar Processing: Feeds like beet pulp and molasses, while palatable and high in carbohydrates, can also contribute to laminitis if not fed in moderation.
- Obesity: Overweight animals are more prone to metabolic disorders like insulin resistance, which increases the risk of laminitis.
How Can Diet Be Managed to Prevent Laminitis?
Careful dietary management is crucial for preventing laminitis:
- Limit Sugar and Starch Intake: Reduce or eliminate high-sugar and starch feeds.
- Controlled Grazing: Limit access to lush pastures, especially during peak fructan levels (early morning and late afternoon).
- Balanced Diet: Ensure a balanced diet with adequate fiber from sources like hay.
- Weight Management: Maintain a healthy weight through appropriate feeding and exercise.
What Other Factors Can Cause Laminitis?
Besides diet, other factors can contribute to laminitis:
- Obesity: Overweight animals are more prone to metabolic disorders like insulin resistance, which increases the risk of laminitis.
- Underlying Diseases: Certain diseases, such as equine metabolic syndrome (EMS) and Cushing’s disease, can increase the risk of laminitis.
- Mechanical Stress: Excessive exercise on hard surfaces or prolonged weight-bearing can also trigger laminitis.

What are the early signs of laminitis?
Early signs of laminitis can be subtle and include mild lameness, increased digital pulse in the hoof, and reluctance to turn. The animal may also stand with its weight shifted back on its heels to relieve pressure on the toes. Early detection and intervention are crucial to prevent the condition from worsening.
How does obesity contribute to laminitis?
Obesity can lead to insulin resistance, a condition where the body’s cells become less responsive to insulin. High insulin levels can disrupt blood flow to the hooves and trigger inflammation, increasing the risk of laminitis. Maintaining a healthy weight is essential for preventing insulin resistance and laminitis.
Can stress cause laminitis?
While stress is not a direct cause of laminitis, it can contribute to the condition in several ways. Stress can disrupt the hormonal balance and immune function, making the animal more susceptible to inflammation and metabolic disturbances. Managing stress through proper care and a stable environment is important for overall health and laminitis prevention.
Managing your animal’s diet and weight, along with regular check-ups, are key to preventing laminitis. Would you like to explore other health conditions related to diet in animals?
