The physiological response of hemostatic system, assessed by measuring camel's bleeding time, was determined immediately before, after and during the recovery (post 3, 6, 24 and 48 hours) from 2 hours exercise and 72 hours of dehydration in 5 clinically healthy Arabian dromedary camels. It was observed that both conditions resulted in an activation of blood coagulation cascades as demonstrated by a drastic reductions (P<0.05) in the overall means of their bleeding times. Nevertheless, 3 hours post each condition were found sufficient (in exercise: P=0.22, in dehydration: P=0.38) for retrieval of bleeding time to its normal level. Based upon findings, it may be recommended that short periods of exercise and/or dehydration prior to surgical operations can be practiced to minimize bleeding during surgery. However, further investigations are required to clarify the possible role of different intensity and/or duration of these conditions on other hemostatic measurements.
