I found following list of formulas to predict iCa value from TP and Albumin in other spp. but i want to know that any specific formula is there for bovines

Formulae for calculated parameters –

1) Corrected Total Calcium (mg/dl) = Total Calcium (mg/dl) + 0.8 ( 4 - Albumin(g/dl))

2) Corrected Total Calcium in mmol/Litre = Corrected Total Calcium (mg/dl) x 0.25

3) Calculated Free Calcium in mmol/Litre

i) % Protein bound = 0.8 x Albumin (g/L) + 0.2 x Globulin (g/L) + 3

ii) Calculated Free Calcium (mg/dl) = Total calcium - Protein bound Calcium

iii) Calculated Free Calcium in mmol/Litre = Calculated Free Calcium (mg/dl) x 0.25

iCa = [0.9 + (0.55 x tCa – 0.3 x albumin)]

iCa = (6 x tCa – TP/3)/(6 + TP)

ctCa = tCa – 0.707 x (albumin – 3.4),
