Abstract: A retrospective study was performed to assess the relationship between serum ionized calcium and calculated serum ionized calcium in dairy animals. Results of 104 apparently healthy dairy animals presented to the Large Animal Medicine Referral Clinic of the Veterinary College and Research Institute, Orathanadu were examined by regression analysis. Analysis of Serum ionized Calcium (iCa), Total Calcium (tCa), Total protein (TP), and albumin concentrations were measured in all samples. Serum concentrations of iCa were measured anaerobically by use of an ion-selective electrode and serum concentrations of tCa, TP, and albumin were measured by use of an automated biochemistry analyzer. Correlation between Total protein (TP), and albumin to the calculated ionized calcium was performed using Pearson correlation and results were interpreted. The predicted low serum ionized calcium values were not due to changes in pH but were associated with hypoalbuminaemia. Adjusted total calcium or total calcium concentrations should not be used for predicting ionized calcium status in dairy animals. The present study revealed that direct measurement of ionized calcium concentration is necessary for accurate assessment of calcium status and also it was concluded that immediate determination of serum iCa in dairy cattle is the ideal to monitor calcium status in transition cows.
