The survey was conducted in three provinces of Gamu Gofa administrative region of Ethiopia, over a period of eight months. Altogether 1,862 cattle, 111 goats, 37 sheep, 42 donkeys and mules and 2 dogs were considered. Almost in 95 % of places, infections were found. The general prevalence of trypanosomiasis in the three provinces was 32 %. Higher prevalence rate in caprines and equines and susceptibility of these species to trypanosome infection, is felt in the survey area. By order of relative importance, the trypanosome species encountered were Trypanosoma congolense, Trypanosoma vivax, Trypanosoma brucei, Trypanosoma theileri and Trypanosoma evansi. Mixed infection and unidentified species were common. Efficiency was tested between thick, thin and wet blood films and microhaematocrit centrifuge technique in diagnosis of trypanosomiasis. Statistical analysis done in body temperature and packed cell volume (PCV) of naturally infected animals and between animals that were found non infected revealed a statistically significant difference in the mean PCVs and variability in the mean body temperature of these groups.
