Incidence of sub clinical mastitis (SCM) was studied during the period from May 2019 to February 2020 in the various small scale private dairy units located in and around Namakkal district of Tamil Nadu. A total of 36 cows were examined in both organized (12 animals) and unorganized farms (24 animals), of which 25 cows were found positive for SCM in both farms. The incidence of SCM was 66.66 per cent (8 animals) and 70.83 per cent (17 animals) in organized and unorganized farms respectively. In the present study, the incidence of grade I SCM in organized and unorganized farms were 37.5 and 52.9 per cent respectively, and grade III SCM accounted for 62.5 and 35.2 per cent in the respective farms. Based on this study the incidence of subclinical mastitis in organized and unorganized small scale farms are almost similar and the grade III subclinical mastitis is comparatively less in unorganized farms.
