Effect of dehydration and rehydration on serum and forestomach osmolality, Nasup+/sup and Ksup+/sup concentrations in iCamelus dromedaries/i.

摘要

This study aimed to monitor the changes in osmolality and concentrations of sodium and potassium ions of serum and forestomach liquor that accompany dehydration and rehydration in dromedary camels. The effects of 7 days dehydration and the following rehydration were examined. Seven days water deprivation significantly elevated PCV, serum osmolality, Na, K and aldosterone concentrations and forestomach liquor osmolality and Na concentration. On the second day of rehydration all tested parameters retained to the pre-dehydration level with the exception of serum aldosterone concentration which maintained at high level to prevent possible haemodilution. The results show rapid recovery of camels when water is available again.
