A total of 136 dairy cows were subjected to test for bovine mastitis by AHI mastitis detector, microbiological test (MT) and California mastitis test (CMT). MT indicated that the most important causative microorganisms isolated from mastitis milk were Staphylococcus aureus (59.3%), Staphylococcus epidermidis (16.4%), Streptococcus agalactiae (12.4%) and Streptococcus uberis (4.4%). In Holstein breed, the critical threshold of electrical conductivity values of normal and mastitic milk were found to be less than 6,900 S and above, 7, 700 S, respectively. Although there was good agreement (92.0%) between AHI mastitis, the diagnostic efficiency of AHI mastitis detector (80.0%) was higher than that of CMT (74.0%) when compared with microbiological findings. In addition, handiness and objectivity of AHI mastitis detector for the detection of mastitic milk suggested that this could effectively be used for the diagnosis of both clinical and subclinical bovine mastitis in field
