Pasture management to minimize the risk of equine laminitis.

The sugar, starch, and fructan content (collectively referred to as nonstructural carbohydrates [NSC]) of pasture plants is dependent on the environmental conditions under which they have grown. Pasture that is stressed by cold, drought, or lack of nutrients can be 2 to 3 times higher in NSC than pasture that grows quickly in warm weather and is adequately watered and fertilized. Horses at risk...

Endocrinopathic Laminitis, Obesity-Associated Laminitis, and Pasture-Associated Laminitis

In a recent online survey, we asked equine practitioners to list the three most common causes of laminitis in horses seen within their practice. We expected veterinarians to list colitis, colic, and retained placenta as the primary causes of laminitis, but many respondents listed obesity, insulin resistance (IR), equine metabolic syndrome (EMS), pituitary pars intermedia dysfunction (PPID), and...

Dietary fructan carbohydrate increases amine production in the equine large intestine: implications for pasture-associated laminitis.

Pasture-induced laminitis in the horse is associated with the overconsumption of fermentable carbohydrate, in the form of simple sugars, fructans, or starch. The fermentation of carbohydrate in the cecum and large intestine results in the production of lactic acid and other toxins or "laminitis trigger factors." Vasoactive amines have been suggested as possible initiating factors. The aim of th...

Equine Laminitis: A Revised Pathophysiology

Vasodilation precedes the development of carbohydrate overload laminitis. Circulating laminitis trigger factors activate lamellar enzymes, which lyse the attachments between the distal phalanx and the inner hoof wall. The clinical signs of laminitis occur when the lamellar architecture disintegrates. The amount of pain correlates with the extent of lamellar pathology. A substance produced by St...

Equine Laminitis: Practical Clinical Considerations

Over the past 20 yr, extensive research efforts as well as clinical experience has greatly increased our knowledge base of equine laminitis. Our present understanding of the disease is that there is failure of the lamellar attachment between the distal phalanx and hoof wall. This, in turn, initiates a sequence of events ranging from no permanent structural damage to loss of the hoof capsule. Af...
