title: 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/1) - 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.
