Abstract:
Recently calved cows (0-2 months) were subjected to blood BHBA estimation and cases with blood BHBA level between the ranges of 1400µmol/L to 2500µmol/L were selected as positive for subclinical ketosis. Cows which were apparently healthy and blood BHBA level less than 1000µmol/L were selected as negative for subclinical ketosis. The blood BHBA with a cut-off between 1400µol/L to 2400µol/L can be potentially useful tool for the routine monitoring of subclinical ketosis in early postpartum dairy cows. The blood BHBA estimation at field level can be done using hand held meter used as the primary monitoring tool and it can replace the need for submitting blood samples to laboratories for BHBA testing.
