The serum and erythrocyte cholinesterase activity and their seasonal variations were determined with 8 males of healthy Korean cattles during one year period from September, 1966 to august, 1977. The results obtained were as follows : 1. The serum cholinestrase activity showed a range of 0.64mg/hr/ml to 8.26mg/hr/ml with a mean value of $3.69{pm}0.25mg/hr/ml$. There was highly significant differences in the seasonal variations. 2. The erythrocyte cholinesterase activity ranged from 29.78mg/hr/ml to 48.88mg/hr/ml with a mean value of $38.37{pm}1.11mg/hr/ml$. Seasonal variations was not found to be significant. 3. The results showed that the serum cholinesterase activity of Korean cattle had great variations among individual values and significant seasonal variations. On the other hand, cholinesterase activity of erythrocyte showed a little variations among individual values and no significant seasonal variations.
