Summary
This retrospective study describes the prevalence of sub-clinical mastitis and consequent In vitro antibiogram assay in cattle population of District Khanewal, Punjab province. The lactating cows (n = 706) were screened through Surf Field Mastitis Test (SFMT) and only positive samples were subjected to antibogram assay, Kirby Bauer Antibiotic Sensitivity Test, using a range of antibiotics commonly used against mastitogens. The prevalence of sub-clinical mastitis was found to be 68.55% (n = 484), whereas, antibogram assay revealed Norfloxacin (42.06%), the most sensitive antibiotic (p < 0.05) followed by Enrofloxacin (30.31%), Chloramphenicol (19.83%), Ciprofloxacin (13.88%), Amoxycilline (12.88%), Gentamycin (8.92%), Colistin sulphate (6.79%), Sulphamethoxazole (6.79%) and Bacitracin (3.68%).
