Adaptability of the dromedary camel to the mineral under-nutrition
The adaptation of camel to desertic conditions leads to remarkable metabolic and physiological mechanisms. The resistance to mineral under-nutrition is one of the faces of this adaptation. Some recent basic researches have gone thoroughly into the knowledges on metabolism of main minerals (calcium, phosphorus, sodium, chloride, magnesium) and trace elements (copper, zinc, selenium). Results show the diversity of the involved mechanisms: increasing of the absorption capacity in scarcity periods, higher storage capacity, tolerance for minerals in excess, maintenance of enzymatic activity in deficient period.
