Abstract: The influence of season on Somatic Cell Counts (SCCs), differential leukocytes (Macrophage (MAC), Lymphocyte (LYM) and Poly Morphonuclear Neutrophils (PMNs)) in camel’s and cow’s milk was compared. Determining the Somatic Cell Count (SCC) in the cow’s milk samples, we established that during the Winter season the somatic cell count was significantly higher in comparison to the dry season (p<0.05). However, our results did not determine significant effect of season on SCC in dromedary milk. In wet season, macrophages were the predominant cell type in camel’s milk and PMN in cow’s milk. In camel’s milk, MAC were the dominant cell type at the wet season and tended to maintain high levels as season changed. In cow, PMN numbers were higher in wet season and declined gradually with advanced season while LYM number increased in dry season (p<0.05). Our results suggest that camels are more resistant to season variation in comparison to cows.
