This experiment was carried out to provide the data of blood chemistry in use of application to clinical diagnosis in racehorses.
Blood was collected from 30 racehorses(♂ 17, ♀ 13). Calcium, inorganic phosphorus, blood glucose, blood urea nitrogen, cholesterol, bilirubin, fibrinogen and ketone body in serum were analyzed as follows.
1. The values of calcium and inorganic phosphorus were maintained a certain level without much variation regardless of sex and species, Ca/P ratio was in the range of 3.13~3.35.
2. The value of blood glucose was 60 ㎎/100㎖, Age and sex of racehorses make no difference in the value.
3. The value of blood urea nitrogen and total cholesterol showed a tendency to increase according to the age. Total cholesterol value was somewhat higher in male than in female.
4. The value of total bilirubin showed a tendency to increase according to the age. There was no difference between sexes in the value.
5. The value of fibrinogen showed no apparent difference with age and sex.
6. Ketone body was negative in all of the cases.
7. There was no variation in the species of the racehorses.
