Racing time(s) is expressed as the mean ± SD. Mean values with the same superscripts differ significantly (capital letters, P<0.01; lowercase letters, P<0.05; based on Student’s t-test following one-way ANOVA). Numbers in parentheses indicate the number of winners/number of runners (Reproduced from M. Oikawa, R. Kusunose, 2005, Vet. J., with permission from Elsevier Ltd.).
