Research overview: Preventing laminitis by studying insulin dynamics in older horses

Laminitis research comes in many forms. Recently, the emphasis has been on understanding the cause of the disease, and developing ways to prevent horses from ever knowing laminitic pain. The emphasis is on understanding how horse management and feeding can effect hormonal balances in older horses, and what recommendations might help horses live longer and healthier lives.

New Laminitis Research from England's Waltham Equine Studies Group

Mark Andrews, our intrepid colleague in England, has published a new edition of his "Equine Science Update", a handy newsletter about equine research and practice. He has written a summary of the scientific output from Waltham's Equine Studies Group in 2004 and 2005 .

Several studies considered the nutritional aspects of laminitis. One showed that grasses with lower nutritive value (such as timothy), or pastures with lower water soluble carbohydrate (WSC) levels are associated with slower fermentation in the colon. Consequently they may be less likely to cause acidosis of the hindgut contents.

Another study demonstrated the existence of marked insulin resistance and / or hyperactive insulin secretion in ponies prone to laminitis.
