Horse Laminitis: Dietary Management and Prevention

Laminitis is one of the most painful conditions affecting horses. Understanding dietary risk factors and prevention strategies protects equine welfare.

Key Facts

Laminitis involves inflammation and disruption of the laminar tissue connecting the hoof wall to the pedal bone
Severe cases cause pedal bone rotation or sinking, potentially requiring euthanasia
Dietary laminitis from excess non-structural carbohydrates (NSC) is the most common form in leisure horses and ponies
Pasture-associated laminitis peaks in spring and autumn when grass fructan levels are highest
Equine metabolic syndrome and PPID are major predisposing conditions for recurrent laminitis
Low NSC forage with NSC under 10-12% is recommended for horses with metabolic syndrome or laminitis history
Early intervention in laminitis significantly improves outcome - acute cases require immediate veterinary attention

Welfare Considerations

Laminitis causes severe acute pain described as equivalent to having fingers slammed in a door across all four feet simultaneously. In chronic cases horses experience persistent pain with every step. Severe rotation or sinking of the pedal bone through the sole represents an extreme welfare crisis requiring difficult end-of-life decisions. The preventable nature of most dietary laminitis cases makes it particularly significant - horses on inappropriate high-sugar diets or unmanaged pasture suffer avoidable agony. Owner education about dietary risk factors is one of the highest-impact welfare interventions in equine care.

What You Can Do

Limit or eliminate pasture access for ponies and horses with laminitis history or metabolic syndrome
Test hay for NSC levels and select forage below 10% NSC for at-risk horses
Use slow feeders and restrict grass access to early morning when fructan levels are naturally lower
Monitor body condition score and maintain appropriate weight as obesity dramatically increases laminitis risk
Recognize early signs including heat in the feet, digital pulses, and reluctance to move - treat as an emergency
Never give grain, apples, carrots, or treats to horses with laminitis or metabolic conditions
Work with a nutritionist experienced in equine metabolic disease for horses with recurrent laminitis
