The objective of this study was to investigate aspartate-amino-transferase (AST), y-glutamyl-transferase (GGT), alkaline phosphatase (ALP), lactate-dehydrogenase (LDH) and acid phosphatase (AcP) activities and semen parameters (volume, pH, concentration, total sperm number (TSN), progressive motility, dead sperm, total morphological defect (TMD) and hypo-osmotic swelling test (HOST)) in seminal plasma of Arabian horses. Furthermore, correlations between enzyme activities and semen parameters were examined. The study was performed using seven healthy Arabian stallions of proven fertility, between 11 and 17 years of age, from the Karacabey Stud Farm in Bursa, Turkey. Overall, 21 semen samples were collected from stallions during the breeding season from March to May. A significant negative correlation was observed between semen volume and concentration of TMD, AST, ALP (P
