Laminitis is an inflammation and damage to the laminae in the hoof of animals, such as horses and cows. It is often triggered by factors like poor diet, obesity, or diseases linked to inflammation. This condition can lead to extreme pain and may even be fatal.
What is the Connection Between Diet and Laminitis?
Diet plays a significant role in the development and management of laminitis, particularly in horses. The modern horse diet, often high in sugars and starches, can disrupt the sensitive balance of the hindgut microbiome.
How Does Diet Trigger Laminitis?
When horses consume excessive amounts of simple carbohydrates, especially sugars and starches, several detrimental processes can occur:
- Hindgut dysbiosis Rapid fermentation of sugars and starches in the hindgut leads to an imbalance in the microbial population. This results in the death of beneficial bacteria and the proliferation of harmful bacteria.
- Toxin release As harmful bacteria die, they release toxins, including endotoxins, into the bloodstream.
- Inflammation These toxins trigger a systemic inflammatory response, affecting the laminae in the hooves.
- Insulin dysregulation High levels of sugars and starches can cause insulin resistance or hyperinsulinemia, exacerbating inflammation and laminitis.
What Dietary Changes Can Help Prevent Laminitis?
Managing a horse’s diet is crucial for preventing and mitigating laminitis. Key strategies include:
- Limit Sugar and Starch Intake Reduce or eliminate grains, sweet feeds, and lush pastures high in fructans (storage form of sugar in plants).
- Choose Low-Carbohydrate Feeds Opt for feeds with low non-structural carbohydrate (NSC) levels.
- Increase Fiber Intake Provide a diet rich in fiber, such as hay, to support healthy hindgut function.
- Use Slow Feeders Slow feeders can help regulate the rate of consumption, preventing sudden spikes in blood sugar.
- Avoid Overfeeding Maintain an appropriate body weight to reduce the risk of obesity-related laminitis.
What Role Does Obesity Play in Laminitis?
Obesity is a significant risk factor for laminitis. Obese horses often have underlying metabolic issues, such as insulin resistance, which increases their susceptibility to laminitis.
How Can Supplements Support Dietary Changes?
Certain supplements can support dietary changes in managing laminitis:
- Probiotics and Prebiotics These can help restore and maintain a healthy hindgut microbiome.
- Antioxidants Antioxidants can help reduce inflammation and oxidative stress.
- Insulin Sensitizers Supplements like magnesium and chromium can improve insulin sensitivity.
What are Some Practical Examples of Diet Management?
Consider these practical examples of diet management for horses prone to laminitis:
- Case Study 1 A horse with a history of laminitis is switched from a grain-based diet to a low-NSC hay diet with added vitamin and mineral supplements.
- Case Study 2 An overweight pony is put on a restricted grazing schedule using a grazing muzzle to limit grass intake.
- Statistical Data Studies show that horses on low-starch diets have a significantly lower incidence of laminitis compared to those on high-starch diets.

How Quickly Can Dietary Changes Impact Laminitis?
Dietary changes can show improvements in laminitis symptoms within a few days, but full recovery may take several weeks to months. Consistent adherence to the new diet is crucial for long-term management.
Can Pasture Grass Cause Laminitis?
Yes, pasture grass, especially during certain times of the year (spring and fall), can be high in sugars and fructans, triggering laminitis in susceptible horses. Careful pasture management and limiting grazing time can help mitigate this risk.
What Other Factors Contribute to Laminitis Besides Diet?
Besides diet, other factors contributing to laminitis include mechanical stress (e.g., excessive exercise on hard surfaces), hormonal imbalances (e.g., Cushing’s disease), and systemic infections. Addressing these underlying issues is essential for comprehensive laminitis management.
How Important is Regular Exercise in Managing Laminitis?
Regular, controlled exercise is important for managing laminitis, as it helps improve insulin sensitivity and maintain a healthy body weight. However, it is crucial to avoid overexertion, especially during acute episodes of laminitis.
What Role Does Farrier Care Play in Laminitis Management?
Proper farrier care is essential for horses with laminitis. Corrective trimming and shoeing can help redistribute weight, support the hoof structures, and alleviate pain.
Diet plays a pivotal role in both the prevention and management of laminitis. By understanding the impact of sugars, starches, and obesity, horse owners can make informed dietary choices to support their horses’ health.
