Totally 120 samples were screened 13 samples as1+,8 samples as 2++ and 3 samples as 3+++ out of 24 subclinical mastitis affected milk samples. On the basis of stage of lactation wise early, mid and late stage of lactation, the prevalence of subclinical mastitis was 28.57%;16.67% and 16.67% respectively. The quarter wise, right forequarter, right hindquarter, left forequarter and left hindquarter, the prevalence of subclinical mastitis was 16.66%;54.17%;8.33% and 20.83% respectively. On the basis of parity, from first to fourth parity, the prevalence of subclinical mastitis was 9.09%;16.66%;25.00% and 25.00% respectively. CMT is a reliable diagnostic method in field conditions.
