Dietary Management of Equine Laminitis: Evidence-Based Approaches

Dietary management is the cornerstone of laminitis prevention and recovery, requiring precise control of non-structural carbohydrates in forage and feed.

Key Facts

Dietary laminitis is triggered by excessive non-structural carbohydrate intake causing insulin dysregulation and lamellar inflammation.
Hay testing for non-structural carbohydrate content is the only reliable method for assessing suitability for laminitis-prone horses.
Soaking hay for 30 to 60 minutes in cold water reduces NSC content by approximately 30 percent.
Grazing must be restricted severely in at-risk horses; spring and autumn grass contains peak NSC concentrations.
Complete removal from pasture during acute laminitis is standard, with careful graduated reintroduction during recovery.
Low NSC complete feeds provide balanced nutrition when hay testing reveals insufficient hay quality.
Body weight management is inseparable from dietary management in obese laminitic horses.

Welfare Considerations

Dietary management of laminitis prevents one of the most severely painful conditions in equine medicine. The lamellar inflammation of active laminitis causes pain comparable to the most severe human pain conditions, and chronic cases cause permanent structural damage affecting every subsequent day of the horse life. Proactive dietary management in susceptible horses prevents acute episodes and preserves quality of life. The precision required, including hay testing and NSC calculation, is significant but achievable for committed owners. The welfare cost of inadequate dietary management, repeated laminitis episodes and progressive structural damage, is far greater than the effort required for prevention. Specialist equine nutrition support makes evidence-based dietary management accessible to most horse owners.

What You Can Do

Test hay NSC content regularly and select hay with less than 10 percent NSC for laminitis-prone horses.
Soak hay in cold water for 30 to 60 minutes before feeding when low-NSC hay is unavailable.
Use grazing muzzles and restrict pasture access during high-NSC risk periods in spring and autumn.
Achieve and maintain healthy body condition score through combined dietary restriction and appropriate exercise.
Consult an equine nutritionist for comprehensive dietary planning for horses with recurring laminitis.
