ABSTRACT
Abdoun K, Alameen A, Elmagbol W, Makkawi T, Al-Haidary A. Dehydration and serum and forestomach
osmolality, Na+ and K+ in Camels. Onl J Vet Res., 30 (1): 1-9, 2026. We describe changes in hematology, osmolality,
sodium and potassium ions in serum and forestomach fluids induced by 7 days dehydration
and rehydration in camels. Packed cell volume (p<0.05) increased 20±3.3%
to 34±3.3% but returned to 20±0.7 by 2nd day rehydration. Serum Na was
enhanced (p<0.05) 145±8.8 to 176±11.3 mmol/L but
reached (150±7.0) on rehydration. Serum K (p<0.05) increased 6.0±0.7 to
7.6±0.6 mmol/L after but did not decline (P > 0.05)
with rehydration. Serum osmolality increased 308±11.8 to 376±12.9 mosmol/L and declined to 301±21.9 with rehydration. Serum
aldosterone (p<0.05) from 42.4±19.4 to 191.8±52.3 pg/ml but did not decreasel (151.3±19.4)
after 2 days rehydration. Sodium in forestomach fluids (p<0.05) was boosted
~45% from 84±6.9 to 122.3±5.8 mmol/L but did not
return to normal by rehydration (100.8± 1.mmol/L). We found no effect of potassium
(K) levels in forestomach liquor. However, forestomach osmolality increased 272.3±26.7
to 346.8±4.7 mosmol/L and fell back to 287.0±14.7 mosmol/L at rehydration.
Key words: Camel, hydration status, blood
composition, forestomach liquor composition.
