Abstract Background Mastitis and associated antimicrobial resistance (AMR) are major challenges to the dairy industry worldwide. Objective This study aimed to expose the mastitis burden, causative bacteria and drivers for mastitis‐causing multi‐drug‐resistant (MDR) Staphylococci infectivity in cows on dairy farms in Wakiso district, Uganda. Methods On 22 farms, practices were documented using questionnaires, and 175 cows were screened by the California mastitis test. Composite milk samples from the positive reactors were submitted to the laboratory for bacterial culture testing. Antimicrobial sensitivity testing by the Kirby Bauer disc diffusion method was done only on Staphylococci with a panel of 10 antimicrobials of clinical relevance. Results Mastitis was detected in 80.6% (n = 141) of the 175 sampled cows, of which sub‐clinical mastitis (76.0%: n = 133) was predominant. The Chi‐squared analysis hypothesized that cow age (p = 0.017), sub‐county (p = 0.013), parity (p
