The present study was performed to investigate the influence of the season on some clinical and haematological parameters of Sudanese camels kept in-door. It was carried out from March 2013 to February 2014 in Tambol Camel Research Center - Gezira State- Sudan. Blood was collected aseptically, from 15clinically healthy non pregnant and not lactating she camels, monthly throughout the experimental period. Red blood cells count, haemoglobin concentration (Hb), packed-cell volume (PCV), total leukocytes count (TLC), differential leukocytes count, glucose, total protein, albumin, globulin cholesterol and triglyceride were determined using the standard laboratory methods. It was found that, rectal temperature increased significantly during summer (37.870 c) compared to winter (37.630 c). Respiration rate was not affected significantly by the season. Significantly lower pulse rate was registered during autumn than that found in summer and winter. The effect of the season on red blood cells count, haemoglobin concentration (Hb) and (MCH) were not insignificant. Significantly lower values of PCV (27.13) and MCV (40.85) were obtained during autumn season and no significant differences were observed between summer (29, 44.09) and winter values. The highest value of (MCHC) was recorded during autumn (39.24) and the lowest value was recorded during winter (35.5). The highest value of the total leukocytes count (TLC) was recorded during autumn (12.56) while the lowest value was recorded during summer (10.3). The lowest neutrophils percentage was observed during winter (44.97) and no variation was found between summer (55.05) and autumn (57.56). The highest values of lymphocytes were recorded during winter season (48.11) but there was a not significant difference between the values of summer (37.4) and autumn seasons (35.67). The seasonal variation of eosinophils, basophils and moncytes were not significant. Serum albumin, total protein, cholesterol and triglyceride were increased during autumn (3.77, 6.54, 53.38, 37.89) compare to summer (2.82, 5.34, 30.42, 27) and winter (3.2, 5.77, 25.27, 34.04). These results were compared and discussed with the findings of previous studies conducted by other researchers.
