In the study, seven previously barefoot horses were trimmed every six weeks with a technique that leveled the hoof to the live sole, lowered the heels, beveled the toe, and rounded the peripheral wall. The sole, frog, and bars were left intact.
"This study has shown that a group of school horses performed well and remained sound when trimmed so that the frog, bars, and sole of the foot were engaged in the weight-bearing function," explained Hilary Clayton, BVMS, PhD, Dipl. ACVSMR, MRCVS, the Mary Anne McPhail Dressage Chair in Equine Sports Medicine at MSU. "We believe it is important for these parts of the foot to contact the ground, not only to distribute the weight-bearing forces and to support the coffin bone from below, but also to provide the horse with proprioceptive input from receptor cells in the heels..."
