A hematological survey was conducted to provide a reference value for Miniature Caspian Pony’s Whole blood profiles and white blood cell differentiation (Percent) and then comparing with those of Iranian Arab horases. Blood samples were taken from 94 clinically healthy Caspian Ponies and 18 Iranian Arab horses. all animals were divided into four age related groups. Group 1, 0 36 months. group 2,37 72 month. group 3. 73 108 months and group 4,
> 109 months. Reference values for normal hematological profiles and percent of white blood cells are showm in table bellow.
Comprehensive statistical studies were subjected on results considering the age, sex and breed. The values of RBC, Hb, PCV, MCV, MCH, segmented neutrophil and neutrophil/lymphocyte ration (N/L) were higher in Iranian Arab horse than Caspian Pony, but the number of WBC and percent of lymphocyte and eosinophil were higher in Caspian Pony. Those significant differences were found between the stalions of two breeds except for MCHC, and the mares of two breeds. There are no significant sex-related differences among male and female of each breed. Age related differences were found in values of Hb, PCV, MCV, MCH, fibrinogen, segmented neutrophils, monocytes and N/L ratio which increase in aged animals. But MCHC, lymphocytes and eosinophil decrease with age.
