The objective of this cross sectional study was to estimate the prevalence of trypanosomes and assess associated risk factors as well as to determine the apparent density of tsetse fly in Edja district. For the prevalence study, dark phase contrast buffy coat examination and Giemsa stained thin blood smears were used; traps were deployed for the entomological survey and apparent density of flies. The entomological survey indicated that Glossina pallidipes and Glossina fusicpes were tsetse fly species caught. The apparent density of 0.64 fly/trap/day was caught from the district. Overall bovine trypanosomosis prevalence of 5.25% was recorded with prevalence of 10.7%, 2.4% and 1.6% in Bate, Degez and Wekya peasant associations, respectively. Trypanosoma congolense and Trypanosoma vivax were detected with prevalence of 71.42% and 28.57%, respectively. Sex-wise prevalence did not show significant difference (p=0.94) between female and male cattle. Although, prevalence of trypanosomosis on age was significantly (p=0.033) higher in adult than young. Of the total 400 cattle examined higher prevalence (9.26%) was observed in cattle with poor body condition followed by 4.38% in medium animals and no infection was observed in good body condition. Based on coat color, prevalence of 8.4%, 0.86% and 2.86% was recorded in black, red and mixed color, respectively. There were differences on the hematological findings of bovine trypanosomosis in anemic than normal animals. The study indicated that trypanosomosis is the major constraint of livestock production in the area that alarms for further detailed investigation.
