Background: The epidemiology of cattle abortion and its association with brucellosis is not well understood in Ethiopia. Therefore, the aim of this study was to determine the magnitude, associated risk factors of abortion, and its association with brucellosis in cattle of Jimma zone, Ethiopia.
Methods: A cross-sectional study was carried out from October 2018 to October 2019 in Jimma zone. A total of 484 pregnant cattle were randomly selected from two districts based on the composition of the cattle population. Besides, blood samples were collected from a total of 484 randomly selected cattle to assess the presence of Brucella antibody. The presence of an antibody against Brucella organism was first tested by the Rose Bengal Plate test, and then positive serum was confirmed using the complement fixation test.
Results: An overall 14.30% cumulative incidence rate of abortion was recorded in study areas. In this study, breed, herd size, method of breeding, previous history of abortion, accessibility of dog to cattle and season were identified as risk factors for the occurrence of cattle abortion. Higher cumulative incidence of abortion (31.82%) was observed in Brucella antibody positive cattle than those of antibody negative cattle (13.42%). However, the difference noted was not statistically significant (P< 0.05).
Conclusion: It is important to create awareness about the impact of the abortion on cattle production and the applicable control technique of abortion should be aimed and implemented. Moreover, further investigation should be conducted to identify the specific cause of abortion and the associated loss in the study areas.
