EXPERIMENTALLY-DERIVED FORMULA FOR COMPUTING SERUM OSMOLARITY IN CHICKENS

RODICA CĂPRIŢĂ, A. CĂPRIŢĂ

Abstract


Osmolarity is a colligative property of solutions that depends on the number ofdissolved particles. The three types of solutes most encountered in biological fluidsare electrolytes, organic non-electrolyte molecules and colloids. The osmolarity ofthe extracellular fluid is about equal to that of the intracellular fluid, although thereare significant differences in the ionic composition of the two compartments. Plasmaosmolarity is a convenient and accurate guide to intracellular osmolarity. There areseveral different formulas for the calculation of human serum osmolarity. The goalof this study is to estimate the plasma osmolarity in chickens from theconcentrations of the main electrolytes and the glucose and urea content, and toestablish the contribution of each osmotic component. Linear regression analysiswas carried out to determine the best predictors of serum osmolarity in chickens.Two equations were also deduced for calculating serum osmolarity using manualregression analysis.
