Comparison of the damping effect of different shoeing by the measurement of hoof acceleration.
The purpose of this study was to compare the damping effect of 16 types of shoeing by measuring hoof acceleration parameters on two trotting horses. At impact, maximal deceleration had extreme values such as 188 m/s2 (+/- 55) for the most damping combination (p < 0.01) and 746 m/s2 (+/- 14) for the steel shoe (mean = 551 m/s2 +/- 125). After the shock, the hoof was exposed to a mean vibrating acceleration at 418 Hz (+/- 84) which was progressively damped in 37.3 ms (+/- 10.5). According to these results, the damping ability of different farriery products significantly reduces (p < 0.05) shocks and vibrations at hoof impact in the athletic horse caused by runs on asphalt or similar surfaces. In practice, the use of the most efficient shoeing should help to reduce the incidence of the over-used joint diseases in the athletic horse caused by runs on hard surfaces.
