    of subclinical mastitis on a well-organized hygienic farm. Analysis of 149 milk samples from individual cows showed that 30 samples (20%) were positive for subclinical mastitis by DMLC (cell count >500 000/ml). 25 samples were positive by the bromothymol blue test but only 13 of these were positive by DMLC test. 17 samples were positive by the Cl- test but only 11 of these were positive by DMLC test. Overall efficiencies of the bromothymol blue and Cl- tests were 80.53 and 83.44% resp. Reasons for false positive and false negative results in both tests are discussed.
