Acid phosphatase of blood leukocytes (AcP) is a lysosomal enzyme which occurs in granulocytes and lymphocytes, but is not found in monocytes. In cattle, the occurrence of AcP polymorphism appeared in the form of A and AB phenotypes controlled by two autosomal alleles. A statistically highly significant repeatability was observed for AcP activity measured in lymphocytes from cows resistant to BLV (bovine leukaemia virus) infection. The highly inherited AcP activity and monogenic nature of AcP polymorphism in cattle allowed us to find out an association between AcP polymorphism and activity of AcP as well as haematological indices. In this study, 60 cows reared in one herd were analysed. The blood samples were collected in the last month before calving and in the first week after calving. The results obtained from cows with phenotype A revealed a statistically higher activity of AcP in lymphocytes whereas a lower activity of this enzyme was recorded in granulocytes. Furthermore, statistically significant differences were also observed in leukocyte number, percentage of lymphocytes and percentage of neutrophils.
