What causes laminitis in horse? (it’s a short story)
A disease of horses and housed dairy cattle, characterized by damage to the sensitive laminae of the
hooves, and clinically by severe lameness, especially in the front hooves. There is heat and pain at the
coronets and in bad cases protrusion of the third phalanx through the sole of the hoof. Hypoxia at the
corium results in defective keratinization and the production of a laminitic ring with the occurrence of
multiple rings in the hooves of animals with chronic laminitis.
Most cases are caused by severe toxemia, as in engorgement on grain or metritis in the mare, and are
called metabolic laminitis. Sporadic cases in heavily pregnant, overfat mares are referred to as puerperal
laminitis. Some are caused by trauma, such as in pawing due to boredom or in horses transported over
long distances without rest, and are called traumatic laminitis. Called also founder.
