Identifying the prevalence and major causing bacteria for mastitis are very important for further improvement of product and productivity of lactating cows. The objectives of this study were to assess and identify the prevalence and major causing bacteria species for existence of bovine mastitis in the study areas. The study was carried out in six districts namely Bedele, Didessa, Dega, Yayo, Mettu and Becho districts. A total of 474 households were participated in the study to carry out an interview and further examination of their cows. The summarized result of the study revealed that 92.9%, 4.4% and 2.7% of the interviewed households in Buno Bedele Zone and 81.1%, 15.7% and 3.2% of the respondents in Ilu Aba Bor Zone have been practicing extensive, semi-intensive and intensive rearing systems, respectively. In addition to this, an interviewed respondents living in Buno Bedele (88.9%) and Ilu Aba Bor (92.0%) Zones had ≤ 10 herd size whereas the remains had >10 herd size. The prevalence of mastitis ranges between 25.6% and 47.9%; the lowest obtained from Mettu district while the highest observed in Dega district. The Staphylococcus aureus was one of the major examined bacteria species from Bedele, Didessa, Dega,Yayo and Becho districts with isolation rate of 57.1%, 69.2%, 67.7%, 65.0% and 34.8% respectively, while Enterobacteriaceae and Micrococcus species were observed as a major causing bacteria in Mettu and Becho districts with isolation rate of 42.9% and 34.8%, respectively.
