Abstract Mastitis is the most economically significant disease affecting lactating dairy cows worldwide. From November 2023 to April 2024, a cross-sectional study was carried out in Maya City, eastern Hararghe zone, assess prevalence of mastitis cows, identify related risk factors, and examine antibiogram profiles Escherichia coli from raw cow milk. Mastitic animals were detected by physical examination udders California Test. Then, bacterial culture biochemical tests employed isolate E. coli. And pattern assessed disk diffusion method. A simple random sampling used choose 353 cows. Of examined for bovine mastitis, 137 positive, with an overall 38.8% (95% CI 33.8–44.1). Out these, 7.1% 4.8–10.3) 31.7% 27.1–36.8) had clinical subclinical respectively. quarter-level 19.4% 15.6–23.9), cases accounting 4.3% 15.1%. Furthermore, 3.6% 1.9–5.6) teats blind. There association (p < 0.05) between factors: lactation stage, body condition score, previous history, teat lesion, farm size, milking mastitic at end, hygiene. Accordingly, lesions four times more likely have than without (OR 4.27; 95% 1.36–13.35). 274 milk samples tested, 22.6% positive . All 62 isolates 100% sensitive ciprofloxacin chloramphenicol. This revealed that moderately prevalent area. Thus, control measures should be developed focus on while considering factors.
