Haematological parameters of the Polish Primitive Horses.

Average values of chosen haematological parameters have been described in a population of 90 clinically normal Polish Primitive Horses. The comparison of the results with values given in literature for horses as a whole and for other breeds enabled us to state that Polish Primitive Horses' blood is characterized by relatively low values of RBC, PCV, segmented neutrophils and monocytes, and high percentage of lymphocytes. It was demonstrated that values of some blood parameters of examined animals are similar to typical results obtained for primitive and cold-blooded horses. Moreover, it was proved that age, sex, and season have influence upon many blood parameters' values of the Polish Primitive Horses. More precise evaluation of results received with that breed will be possible when that influence is taken into consideration.
