Abstract: In order to assess the compartmental water management of Marwari sheep various body water compartments were determined during the periods of control, dehydration and rehydration.The control mean values of total body water, extracellular, plasma volume, blood volume, red cell volume, intracellular fluid volume and interstitial fluid volume were 20.0 ± 0.8, 1.80 ± 0.1, 2.8 ± 0.20, 0.56 ± 0.02, 9.3 ± 0.4, 11.0 ± 0.4 and 7.5 ± 0.3 litre, respectively, thereby forming 64.26%, 5.78, 8.99, 1.79, 29.88, 35.34 and 24.10% of the body mass, respectively.Significant (P≤0.05) decline was found with progression of dehydration in all the water compartments with a different pattern.Maximum loss was observed from the plasma volume (50%), whereas minimum loss was in the intracellular fluid compartment.Again upon rehydration, the pattern of water replenishment was different in various compartments.Immediately after rehydration the maximum gain was observed in blood volume and the slowest gain in intracellular and red cell fluid compartments.Decreased plasma volume was related with a significantly (P≤0.05)higher serum aldosterone during dehydration period.Simultaneously, dehydration functioning as a stress increased the levels of serum cortisol accompanied by increase in serum creatinine, creatine kinase, γ-glutamyl transferase and alkaline phosphatase activities significantly (P≤0.05).
