A cross sectional study was conducted in Andracha woreda Sheka Zone of South western Ethiopia to determine the prevalence and associated risk factors of bovine trypanosomiasis using parasitological and entomological study. It was conducted from November, 2015 to April, 2016. Blood samples from randomly selected 383 cattle of both sex and different age groups were collected and examined with hematological and parasitological techniques. Out of the total examined cattle, 8(2.1%) were infected

The disease was more prevalent (2.3%) in females than in male cattle (0.2%). There were no statistically significant difference among / between age and sex groups (P>0.05). The mean PCV (%) values during the study period were 23.38 ± 1.51 in parasitaemic and 30.02 ± 0.14 in aparasitaemic animals, which was found statistically significant (P<0.05). Glossina pallidipes were the only fly species caught during the study period and the entomological monitoring showed that the apparent density (expressed as flies per trap per day, i.e. f/t/d) of Glossina Pallidipes in the study area were 0.83, 0.89, 1.11 and 0.44 at Yokchichi, Gemadro, Beshifa and Shebena, respectively; with the overall apparent density of 0.82. Since it is endemic diseases, strategic control of bovine trypanosomiasis including vector control should be strengthened to improve livestock production in this area.
