Abstract
The aim of this study was to investigate the antimicrobial sensitivity patterns of commonly used antibiotics against bovine subclinical mastitis in and around Chennai. A total of 105 milk samples were screened, out of that 30 milk samples were showed positive for subclinical mastitis. Subclinical mastitis was diagnosed by California Mastitis Test (CMT). The in vitro antibiogram studies of the mixed culture of organisms from mastitis milk revealed clindamycin to be most effective drug (66.67%) followed by Ceftriaxone, Chloramphenicol (56.67%) and enrofloxacin (50%). Other antibiotics were showed less than 50% sensitivity against organisms from mastitis milk
