“…The present result revealed that the trypanosome species encountered in the area were T. vivax, T. congolense and T. brucei. These three species of trypanosomes were also reported from western and south western part of Ethiopia by Lemecha et al [14] in Ghibe valley, Tilahun et al [15] in Dale Sadi district; Habte et al [16] in Darimu district and Lelisa et al [17] in southwestern Ethiopia. The study showed that T. vivax was the predominant (65.73%) species in the area.…”

The study was conducted from October 2015 to November 2015 in Gambela and Abobo districts of Gambela Peoples Regional State, southwestern Ethiopia. It was designed to avail information on prevalence of bovine trypanosomosis and apparent densities of vectors of the trypanosomosis. A parasitological study using buffy coat technique was employed for the determination of prevalence of trypanosomosis while baited mono pyramidal traps were used for the vector survey. A total of 862 cattle randomly selected from the study population were examined for the parasitological study. The result of parasitological study revealed that the overall prevalence of trypanosomosis was found to be 16.59%, 95% CI=14.10-19.08 indicating trypanosomosis is a serious problem in the area. Three Trypanosoma species were identified during the study period: Trypanosoma brucei, T. vivax and T. congolense. Highest trypanosome prevalence (18.67%) was seen in animals with poor condition than that of those with medium (16.76%) and good (14.20%) body condition for the concerned blood parasite but no significant difference was observed (P>0.05). Higher infection rate was occurred in male (18.35%) than female (14.79%) cattle without significant difference (P>0.05). Prevalence was significantly higher in adult animals (17.95%) than younger ones (7.27%) (P>0.05). The study suggested that mean PCV values of parasitaemic (21.13%) cattle was significantly lower than aparasitaemic (22.26%) animals (P<0.05). During entomological survey, four species of tsetse fly: G. tachnoides, G. morsitsns submorsitans, G. pallidipes and G. fuscipes fuscipes and three genera of other biting flies: Tabanus, Haematopota and Stomoxys spp. were caught. The overall apparent density of tsetse flies was 0.75 fly/trap/day. Trypanosomosis and tsetse fly pose great threat to cattle residing in study areas. Thus, appropriate intervention measures need to be taken.

“…Anecdotal reports of the presence of trypanotolerance in some Ethiopian cattle populations had, until recently not yet been confirmed. Based on the observation that some indigenous breeds continue to be kept by smallholder livestock keepers in tsetse infested, trypanosomosis endemic areas of south-western Ethiopia, a study of trypanotolerance attributes is currently under way (Lemecha et al 2006). It is conducted in the Ghibe valley at a field experimental station and includes the four indigenous cattle breeds Abigar, Gurage, Horro and Sheko.…”

Four cattle breeds indigenous to western and south-western Ethiopia--Abigar, Gurage, Horro and Sheko--were included in a study of the perceptions of smallholder cattle keepers regarding cattle management, production levels and constraints for production. A semi-structured questionnaire was used and 60 cattle keepers from each of the four areas were interviewed. Diseases were reported as the main constraint to cattle production by a majority of livestock keepers in all areas except in the Sheko area, where over-stocking was the main constraint. Among diseases, trypanosomosis was the main livestock disease according to more than half of Gurage, Horro and Sheko keepers, whereas anthrax was most important in the Abigar area. Gurage had highest age at first calving, longest calving interval and also the lowest milk production, whereas Sheko and Abigar had the most favorable characteristics both for milk production (600-700 kg) and fertility (age at first mating 3-3.5 years and above 8 calves/cow). Cattle keepers in the Sheko area reported relatively less problems with cattle diseases compared to the other areas, especially regarding trypanosomosis. Abigar showed a different disease pattern than the other breeds and may also have advantages as regards trypanotolerance.

Like their smallholder subsistence counterparts in developing countries, breed and trait preferences of Sheko cattle keepers have broad perspectives. Our study has documented breed and trait preferences of Sheko cattle keepers in southwestern Ethiopia--the natural breeding tract of Sheko cattle. Our results showed that due to their multifunctionality, cattle are the most preferred livestock species. Overall, farmers showed slightly more preference to local Zebus over Sheko breed. This is due to voracious feeding behavior of Sheko cattle, which make them less preferable in the face of worsening feed shortage, and due to aggressive temperament of Sheko cattle. This is despite Sheko's outperforming potential over local Zebus in their milk production, draft power, and hardiness. At trait level, overall milk production was consistently reported as the most preferred trait followed by fertility and traction. This trait preference rank has matched with the reported frequency count ranks for Sheko cattle use. However, breed preference rank has not matched with reported trait preference ranks because Sheko excels local Zebus in all the three most preferred traits, but it was ranked second. Therefore, to minimize these conflicting interests, breed management plans for Sheko cattle should target on strategies that help to solve feed shortage problem and to improve feeding practices, and on selection of less aggressive Sheko cattle. Therefore, these strategies should be considered in line with Sheko cattle conservation and genetic improvement programs.
