Abstract: The purpose of the study was to investigate normal baseline levels of retinal and alpha tocopherol in clinically healthy camels (Camelus dromedarius), kept under natural grazing conditions. A total of 275 Arabi camels of both sexes were sampled over a one-year field survey at Butana area, central Sudan. The overall mean concentration of retinal was 479.5�69.4 ng/L, whereas alpha tocopherol was 2.1�0.4 mg/L. Sex showed insignificant effect of vitamin levels. However, season exerted a significant effect; the rainy season (July-October) showed the highest level 493.5�80.3 ng/L and 2.3�0.5 mg/L for retinal and alpha tocopherol, respectively. The corresponding figures for the dry season (January-May) were 400.3�70.0 ng/L and 1.4�0.4 mg/L, respectively. Age influences vitamin levels with adult having higher status.
