The present study was carried out to investigate the serum enzyme activities of racehorses.
The enzymes investigated were aspartate and alanine aminotransferase (GOT, GPT), r-glutamyl transpeptidase(γ-GTP), Lactic dehydrogenase(LDH), creatine phosphokinase(CPK), and alkaline phosphatase(ALP).
Animals used were 30 healthy racehorses(♀17, ♂13) average weighing 435㎏ 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 γ-GPT activities were not changed with age but ALP activity tended to be decreased wish age. Activities of GOT, GPT, γ-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.
