Abstract

The present study was carried out to investigate the serum enzyme activities of racehorses. The enzymes investigated were aspartate and alanine aminotransferase (GOT, GPT), ${gamma}$-glutamyl transpeptidase(${gamma}$-GTP), Lactic dehydrogenase(LDH), creatine phosphokinase(CPK), and alkaline phosphatase(ALP). Animals used were 30 healthy racehorses(♀17, ♂13) average weighing 435kg and were from 2 to 8 years of age. LDH activity was progressively decreased with age and next in the order of GOT and CPK activities. GOT and ${gamma}$-GPT activities were not changed with age but ALP activity tended to be decreased wish age. Activities of GOT, GPT, ${gamma}$-GTP and ALP were higher in female than in male. There was no difference in CPK activity by sex, and no difference was found out among breeds.
