Comparative efficacy of indirect tests for detection of sub clinical mastitis (SCM) in goats

Total of 220 graded Jamunapari lactating goats were examined. Milk samples from each udder-half were collected separately in sterile test tubes under aseptic conditions for MWST (Modified white side test), BTB (Bromo thymol blue), MCMT(Modified California Mastitis test) and SCC (Somatic cell count). Out of 220 goats 213 goats were found positive for SCM and out of these 213 goats 112 (52.59%) were found positive for SCM by Somatic cell count (SCC). The comparative efficacy of BTB, MWST and MCMT was determined by taking somatic cell count as a standard method for diagnosis of SCM. In the present study MCMT was found most sensitive, as there was 78.57% correlation with SCC, followed by MWST (57.14%) and BTB (50.89%).Therefore, MCMT could be used as the most sensitive indirect test for diagnosis of the subclinical mastitis in goats.
