Title:A vemhesség hatása a hematológiai paraméterekre lipicai kancákban
SUMMARY Specific haematological reference values are necessary for each animal species, regarding the age, breed, sex and reproductive status. A total of thirty (23 pregnant and 7 non-pregnant) Lipizzaner broodmares’ blood samples were analysed for haematological parameters in this study in relation to their gestation status (pregnant/non-pregnant) and the gestational period (early-mid/late pregnant). The haematocrit, haemoglobin, red blood cell count and platelet count was significantly higher in pregnant mares compared to their non-pregnant barnmates. Regarding the period of gestation, the late pregnant mares (D > 210 of gestation) had higher granulocyte- and white blood cell count, but lower mean corpuscular haemoglobin than those in the earlier stages of pregnancy. The age of the mares did not affect the haematological parameters in this study.
