Abstract: In this paper we focus on the breeding of Slovak spotted cattle in conventional breeding conditions at a farm in the Prešov region and on the selected biochemical parameters. In the work we monitor the enzymatic activity values of selected enzymes (ALP – alkaline phosphatase and ALT – alanine aminotransferase) in the blood serum of Slovak spotted cattle. The enzymatic activity of selected enzymes were measured in the blood serum of dairy cows (n=20) in the middle of lactation. Blood samples were collected twice a year (autumn and spring). For determination of enzymatic activity we used biochemical analyzer Cobas Integra 400 plus (Roche). The ALP activity of the autumn blood samples (0.57 ± 0.19 μkat/L) was not significantly lower in comparison with the ALP activity of the spring blood samples (0.64 ± 0.29 μkat/L). The ALT activity of the autumn blood samples (0.35 ± 0.08 μkat/L) was significantly lower (p<0.05) in comparison with the ALP activity of the spring blood samples (0.55 ± 0.09 μkat/L).
