We estimated the incidence of clinical mastitis (CM) and antimicrobial agent (AMA) usage for its treatment in an organized dairy farm over a period of six months. The incidence of mastitis at different stages of lactation was also quantified. The incidence of mastitis was higher in Sahiwal cows (9.52%) compared to crossbred cows (3.61%). Among different AMA usage, enrofloxacin (22%), ampicilin with cloxacillin (18.57%), gentamicin (18.29) and ceftriaxone (12.57%) drugs were most commonly used against CM cases. Penicillin group and their combinations (29.43%) was found to be the most commonly used AMA for CM followed by fluoroquinolone (22%), aminoglycosides groups (21.43%) and cephalosporins group (16.86%) of drugs. Tetracyclines (9.14%) and chloramphenicol (1.14%) were least choice as evidenced by less frequent usage. From the findings of the study it may be concluded that the incidence of mastitis was high in Sahiwal cows milked with machine milking system and mastitis animals needed an average of five days treatment for clinical cure. Further, â-lactam group of antimicrobial drugs were predominantly used in mastitis treatment, despite entry of new AMA in the market.
