Serum iron and the binding capacity of serum were investigated in 66 pack and 70 riding camels in the Sudan. The total iron-binding capacity was comparable with means and ranges recorded for other domestic animals but the serum iron and the saturation concentration were both lower. Intersex differences were observed only in the total iron-binding capacity and the saturation concentration. Both serum iron and total iron-binding capacity were greater in the riding than in the pack animals. The results also suggested absence of relationship between the process of ageing in the camel and the various parameters.
