Normal haematological values need to be defined for each breed in order to increase diagnostic precision. No published data on haematology exists for Arabian horses raised in Algeria. Hematological examination, in horses, has been performed for a variety of reasons: as a screening procedure to examine general health of the animal, as an adjunct to a patient’s infection and to evaluate the progress of certain disease conditions. This research compares the haematological characteristics of post-partum pure bred Arabian mares of different ages. Twenty pure bred Arabian mares were used in this study. Four age groups with five mares each one: A (5–10 years), B (10–15), C (15–20) and D (>20 years). Jugular blood samples were taken and data were pooled for each animal. In this study, the number of Red Blood Cells (RBC), hemoglobin concentration (Hb), Packed Cell Volume (PCV), average volume of red blood cells in the blood (MCV), and total number of leukocytes (WBC), Mean Corpuscular Haemoglobin (MCH) Mean Corpuscular Hemoglobin Concentration (MCHC), and platelets number were determined. In this study, a significant difference was observed between the post-partum mares with different groups of age in total erythrocyte counts, Haemoglobin and Packed cell volume P<0.05.
