Relation of Plasma Calcium to Total Protein and Albumin in African Grey (Psittacus Erithacus) and Amazon (Amazona Spp.) Parrots

Abstract

A significant correlation was found between total calcium and albumin concentration in the plasma of 70 African grey parrots (r=0.37; P<0.05). A correlation formula for plasma calcium concentration in the African grey parrot was derived on the basis of the concentration of albumin: Adjusted Ca (mmol/1) = Ca (mmol/I) - 0.015 Albumin (g/1) + 0.4. About 14% of the variability in calcium was attributable to the change in the concentration of plasma albumin concentration (R2=0.137). The correlation between calcium and total protein in African greys and between calcium and albumin and calcium and total protein in Amazons was not significant. © 1964, Taylor & Francis Group, LLC.
