Haematological Variations before and after Blood Transfusion in Arabian Racing Camels (Camelus dromedarius)

In this experiment, a haematological comparison has been done before and after whole blood transfusion in 5 racing camels (2 years old). The donated blood withdrawn from only one camel to fix the other variation factor from different blood from different donor camels. The variation was clear in some haematological parameters like red blood cells (RBC), haemoglobin (Hb), haematocrit (HCT), platelets (PLT). The reticulocytes count showed significant steady changes and could rely on this value as an indicator of blood transfusion in Arabian racing camels according to the results of this experiment and many other individual cases outside this experiment. The leukocytes and differential leukocyte percentages did not showed significant changes after blood transfusion. The immunological reactions against antigens on red blood cells of donor camel determine the variation in haematological changes after blood transfusion. However, the immunological reaction becomes with limited values especially in the first time of blood transfusion.
