Abstract: Today, the sport has become a more important use for horses. The aim of the present was to
predict the race speed or performance of Thoroughbred racehorses. For this reason, using
parameters of sex, race age, dam age, race track, race distance, city, horse age taken body
measurement and body measurements, the aim is to use regression tree analysis to identify the
most important predictor of race speed. The racing records (2445 races) of Thoroughbred
racehorses (46 males and 28 females, total 74 horses) in this study were provided by the Turkey
Jockey Club. As a result, putting into consideration the relative importance of race track in
constructing regresyon tree, it could be inferred that Thoroughbred racehorses running turf track
would be 'speedy'. In the races on the dirt track, the effect of cities on the horses' speed was
found to be significant. Especially the high speed of horses in Istanbul has come into prominence
among the provinces. In addition, cannon bone circumferences of 22.5 cm or smaller and chest
circumferences greater than 174.5 cm in Thoroughbred horses were observed to positively affect
the speed. |
