Variability factors in trace elements nutritional status by plasmatic indicators in camel (Camelus dromedarius) in Morocco. II. Effect of mineral supplement

Abstract

Four groups of 5 camels received one injection of copper and zinc (IM group), an oral supplementation during one month with copper sulphate (CU group), or zinc sulphate (Zn group), and no supplementation (T group) respectively. The trial was performed during 111 days and complementation occurred from day 7 to 37. In the IM group, cupremia and zincemia significantly increased (72 and 73 µg/l00 ml maximum respectively). Cupremia increased in Cu group as zincemia in Zn group but the observed values did not overpass the threshold of admitted deficiency limit, and fall down fastly after the end of the supplementation period. The interaction copper-zinc explained the non-significant decreasing of zincemia in Cu group and significant decreasing of cupremia in Zn group.
