Abstract. Concentrations of haematological parameters in five Standardbred mares were determined at rest and after race, as well as blood plasma dehydration factor D_f, TAS and TAS x D_f, and fast plasma reductans (FPR) and FPR x D_f. An increase in PLT, WBC and RBC values was observed after intensive race, as well as a significant growth in HGB and HCT concentrations values. The RBC x HGB values at rest observed in this study are characteristic of good horse preparation to aerobic exercise. The observed post-exercise drop in the TAS concentration was significant, while that in the FPR concentration was insignificant. It is apparent that post-exercise horse blood parameters should be examined in association with organism dehydration degree.
