Abstract: A cross sectional study was conducted at Didessa District, Oromia region, south west Ethiopia. The study was carried out from November, 2011 to April 2012 on indigenous cattle breed managed under mixed crop-livestock production system, to determine the prevalence of bovine trypanosomosis. This study employs parasitological survey by the use of Buffy coat examination, thin smear and hematological study. The overall prevalence of bovine trypanosomosis in the present study was 5.47%. The predominant species recovered was Trypanosme congolense (61.9%) followed by Trypanosome vivax (23.8%) the Trypanasome brucei (9.5%). Mixed infection due to trypanosome congolense and Trypanosome vivax (4.7%) was also recorded in the study. Discrepancy in the prevalence of trypanosome infection was recorded in the different age groups, between sex and different body conditioned animals, but the difference was not statistically significant (p>0.05). The mean PCV of parasitemic animals was significantly lower (21.15 ± 4.675) than the aparasitemic animals (24.316 ± 4.93) (p<0.05). Although the present study came up with low prevalence of bovine trypanosomosis in the study area, the potential impact of this disease on production and productivity of cattle shall not be undermined. Therefore, sustainable community based tsetse and trypanosomosis control program should be implemented.
