ABSTRACT
Abdoun K, Alameen A, Elmagbol W, Makkawi T, Al-Haidary A., Effect of dehydration and rehydration on serum
and forestomach osmolality, Na+ and K+ concentrations in Camelus
dromedaries. Onl J Vet Res, 11 (2): 143-152, 2010. Changes in osmolality and concentrations of
sodium and potassium ions of serum and forestomach liquor in dehydrated and
rehydration in dromedary camels are described. Effect of 7
days dehydration followed by rehydration were evaluated. Water
deprivation elevated PCV, serum osmolality, Na+, K+ and
aldosterone concentrations and forestomach liquor osmolality and Na
concentration (P < 0.05). By the 2nd day of rehydration all
tested parameters returned to pre-dehydration values except for serum
aldosterone concentration which remained at high levels. We believe that this
may prevent haemodilution. Our findings suggest rapid rehydration
in camels.
Key words: Camel, hydration status, blood
composition, forestomach liquor composition.
