A cross sectional study was conducted in Oromia and Regional state of SNNPRS from August 2006 to April 2007 to determine the prevalence of brucellosis in goats and sheep and areas associated risk factors using mRBT and CFT. A total of 2905 goats and 1059 sheep were included in this study.rnThe modified Rose Bengal Test (mRBT) prevalence rate in goats’ over all is 5.5% (n=2905) while in sheep is 4.0% (n=1059) and total in small ruminants 5.1% (n=3964) in extensive farming system. The mRBT positive rates, in relation to production systems are 7.11% and 0.5% in pastoral and sedentary respectively. In the intensive farming system, in Adami Tullu Agricultural Research Center, no sero-positive animals while in Awassa Agricultural College, the prevalence rate is 20% by mRBT.rnThe serial test positives (mRBT and CFT) prevalence rate in goats is 3.2% (n=2905) while in sheep is 1.6% (n=1059). The small ruminants’ prevalence rates are 3.9% and 0.33% in pastoral and sedentary production systems respectively. In the intensive farming system, in Adami Tullu Agricultural Research Center, no sero-positive animals while in Awassa Agricultural College, the prevalence rate is 18.4 % by serial tests.rnRisk factors analysis was carried out in relation to production system, species and sex and significant differences were observed to counter categories (p
