The hoof parameters - hoof angle, toe length, heel length, hoof width, hoof length, heel width, hoof circumference - of 1372 Thoroughbred racehorses in Seoul racecourse were measured. Each parameter was compared with the racing time. The parameters were as follows: fore hoof angle 50.1±0.09°, hind hoof angle 50.1±0.08°; fore toe fength 82.8±0.21mm, hind toe length 88.8±0.23mm; fore heel length 28.6±0.19mm, hind heel length 24.5±0.19mm; fore hoof width 130.9±0.30mm, hind hoof width 125.7±0.28mm; fore hoof length 133.3±0.22mm, hind hoof length 28.1±0.22mm; fore heel width 61.2±0.32mm, hind heel width 67.9π0.35mm; fore hoof circumference 264.2±0.48mm, hind hoof circumference 253.8±0.40mm. Apart from the hoof angle, the hoof parameters increased in proportion to the body weight. The parameters of forelimbs affected the racing time more than those of hindlimbs. The correlation between hoof parameters and racing time was shown more in short-distance race (1000M) than in long-distance race(2200M). The parameters that had correlation with racing time were hoof width, hoof length, heel width of forelimbs and heel width of hindlimbs.
