S.122003621Thirty-two female camels were utilized in this study while living in their natural habitat (low rain Savannah). Copper (Cu) and zinc (Zn) profile were examined in young, pregnant and lactating camels with different yields. The data analysis revealed that, serum values of both Cu and Zn were within the normal range, although Zn concentration decreased significantly in fourth gestation. Changes in Cu concentrations due to physiological states were not detected. However, at the minimum range serum Cu level tended to increase with advancement of age. Medium milk yielder showed the highest Cu levels at both minimum and maximum ranges. Zn means serum concentration increased significantly with advancement of age but dropped significantly during fourth gestation (10-11 years old). No significant differences could be detected in Zn values among camels with different yields.]]>Abu-Sin, M.E.,19701970Darrag, A.,19891989Espinosa, J.E., L.R. McDowell, R. Juan, J.K. Loosli, J.
