NSC and ACTH--Double trouble in the fall

By Juliet M. Getty, Ph.D.

Horses are more likely to suffer from laminitis in the fall than any other time of year. Two reasons—high NSC (non-structural carbohydrates) from cooler nighttime temperatures and increased blood ACTH (adrenocorticotropic hormone) secretion from the pituitary gland. Both of these lead to elevated insulin.

Insulin rise = laminitis

Simple sugars (denoted as ethanol soluble carbohydrates—ESC, on your hay analysis report) along with starch, are digested down to glucose. Once glucose enters the bloodstream, it signals the pancreas to produce insulin. Elevated insulin is the most common cause of laminitis. It stimulates the production of “insulin-like growth factors” within the hoof’s laminae, resulting in proliferation of the epidermal layer. The laminae have two intermeshed layers, the epidermal and the dermal layers. When the epidermal layer lengthens and stretches with uncontrolled growth, it can weaken the laminae. This can lead to a structural failure by compromising the connection of the coffin bone to the hoof wall, creating a gap between the wall and the sole. You may see some hemorrhaging under your horse’s foot—an indication of laminitis.
