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),
