abstract
Mastitis is the widely prevalent malady of dairy cattle. The present study aimed at finding the prevalence of bovine mastitis in Mizoram and to explore the treatment options with different antibiotics after determining the etiology. Hundred animals from 18 different farms were screened using modified California Mastitis test and recorded as positive and negative based on appearance of precipitation. An overall incidence rate of mastitis was observed as 72%. The milk samples were collected from positive animals, and microbial etiology were determined using appropriate laboratory techniques. The different organisms isolated were Staphylococci, Streptococci and E. coli. Animals were grouped into three groups and treated with Ceftizoxime, Cefoperazone sodium, Cefquinome sulphate and Cefquinome sulphate. It is observed that the third group where, Cefquinome sulphate and Cefquinome sulphate used showed 100% cure. These observations necessitate the requirement of regular screening of cattle and application of preventive and control measures for mastitis.
