ABSTRACT: A cross-sectional study to determine the prevalence of bovine trypanosomosis was carried out in Chena district, Kefa zone, southwest Ethiopia from September 2010 to January 2011. Blood samples were collected from 391 randomly selected local (zebu) breed cattle in three representative peasant associations (PAs). The buffy coat and Giemsa stained thin blood films examination techniques were used for parasite detection and identification. The packed cell volume (PCV) estimation was also conducted. From a total of 391 cattle, 6.9% (n = 27) of the animals were found positive for trypanosome infection. The trypanosome species observed across the study animals were T. congolense (4.89%), T. vivax (1.54%), and T. b. brucei (0.51%) as single infections. The infection rate of T. congolense and T. b. brucei varied significantly (P 0.05) in infection rate was found between male (7.79%) and female (5.62%) animals. The prevalence was 2.24% and 8.29% in young and adult cattle, respectively with significant difference (P
