ABSTRACT
The activity of ceruloplasmin (Cp), alkaline phosphatase (AP), acid phosphatase (AcP) and amylase (Am) in the serum of Hucul mares and stallions divided into age groups (weanlings, yearlings, 2-years-old and adults) was estimated during the winter feeding season. Statistically significant and highly significant differences were found in the activity of enzymes between age groups of stallions and mares. Activity levels of Cp, AP and AcP in individual age groups were mostly higher in the serum of mares than in stallions, except for Am. The AP activity decreased with age, from 5.62 to 2.94 IU/l in mares and from 4.78 to 2.99 IU/l in stallions.
