Effect of dehydration and rehydration on serum and forestomach
osmolality, Na+ and K+ concentrations in Camelus dromedaries. Online J Vet Res, 11 (2): 143-152, 2010.
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.
