Abstract

Detection of cases of subclinical mastitis presents difficulties because in early stages of the disease clear cut clinical changes are not manifested. A total of 200 milk samples from apparently healthy quarters of 50 healthy crossbred dairy cows in different stages of lactation, were taken and subjected to estimation of various constituents like lactose, Na+, K+ and Cl− alongwith indirect diagnostic tests like electrical conductivity, sodium lauryl sulphate and bromothymol blue card test. Each reading of different tests was compared with bacteriological finding and overall percentage of agreement was calculated for each test. The percentage of agreement of electrical conductivity, lactose, BTB, SLST, sodium, chloride and potassium was 69.38, 71.47, 77.66, 76.15, 67.63, 70.87 and 55.00 respectively.
