The equine hoof is often manipulated in purpose to achieve a better stride or to reduce the weight on damaged tissue. The living tissue in the hoof can't store energy as glycogen and is therefore depending on a continuous supply of glucose for its energy production. The purpose of the study was to determine if wedging (i.e. elevating) the heel could influence the hooves glucose and lactate consumption/production. Five standardbred horses were trained to trot on a treadmill without getting physical or mentally tired. Before the experiment started three catheters were placed in vena digitalis lateralis (digital vein), vena jugularis (jugular vein) and arteria temporalis superficialis (facial artery). The horses trotted for three periods ea...
