The objective of this study was to determine ranges of haematological and biochemical parameters of Przewalski horses ( Equus przewalski) kept in the Czech Republic, to compare the results with data reported for the same species as well as for domestic horses ( Equus caballus), and to evaluate differences between both genders and age groups. Stallions showed significantly higher counts of red blood cells and bands, higher levels of total bilirubin and magnesium, and a higher activity of GGT. Higher concentrations of cholesterol, vitamin A and sodium were found in mares. Young animals were characterised by a lower count of eosinophilic granulocytes, a higher activity of ALP and higher concentrations of calcium, inorganic phosphorus, sodium and creatinine. Other differences were not significant.
