Study on the prevalence and associated risk factors of bovine trypanosomiasis in Zaba Gazo Woreda, Southern Ethiopia.

ABSTRACT

In tsetse-infested areas of Ethiopia, African Animal Trypanosomiasis is the most serious threat to livestock productivity. A cross-sectional study was conducted from May 2021 to September 2021 in the Zaba Gazo district to assess the prevalence and associated risk factors of bovine trypanosomiasis through parasitological and hematological techniques. In the current study, the overall prevalence of trypanosomiasis was found to be 21%. Among anticipated risk factors, the origin of animals has shown a statistically significant association (p < 0.05) with the occurrence of bovine trypanosomiasis. Other potential risk factors, such as sex, age, BCS, coat color, and agroecology, were not shown to have a statistically significant relationship (p > 0.05) with trypanosomiasis. The overall mean PCV values for parasitaemic and aparasitaemic cattle were 23.24 ± 3.04SD and 27.37 ± 4.18SD, respectively, thus it was lower in parasitaemic animals than the aparasitaemic animals. A high prevalence of bovine trypanosomiasis in the study area necessitates an integrated parasite and vector control approach to curve the prevalence and effect of the disease.
