A cross sectional study was carried out from November 2017 to December 2017 to assess the status of subclinical mastitis in Ejersa lefo District Oromia region Ethiopia. Study animals were selected using simple random sampling technique. Out of 384 examined (Borena 9, cross breed 45 and local breed 330) 111 cow were found to be affected with subclinical mastitis with prevalence of 28.9%. The result from the severity grading of the infection indicates that out of 111 positive cows 70 (63.3%) cows had weak infection, 17 (15.3%) had distinct positive and 24 (21.6%) cows had strong positive infection. The highest occurrence of subclinical mastitis was recorded in local breed (82.9%), old age group (83.7%), sixth parity (36%), and first lactation stage (36.9%). Cows having poor teat hygiene and kept in poor barn hygiene were 82% and 79.5% infected with subclinical mastitis. In this study subclinical mastitis was major mammary gland health problems of the dairy cows, which cause huge loss of milk production that assure serious attention in creating awareness and prevention strategy.
