Background: Ticks cause substantial losses in cattle production, in terms of diseases, and reduced productivity, and are economically the most important ectoparasites of cattle. Methods: A cross-section study was conducted from January 2022 to August 2022 in the Bedele district to identify genera and species of Ixodid ticks infesting cattle and determine the prevalence concerning host-related factors. Adult ixodid ticks were collected from 384 randomly selected cattle by using forceps and preserved in separate collecting bottles with 70% ethyl alcohol. The collected ticks were identified under stereomicroscope into species based on their morphology. Results: Out of the 384 cattle examined, 276 (71.9%) were found with being infested by one or more tick species. A total of 3192 ticks were collected and identified. Three genera; namely Amblyomma, Boophilus and Rhipicephalus, and four species (Amb. cohaerence, Boophilus decoloratus, Amb. variegatem, and Rhip. evertsi evertsi) were identified with a prevalence rate of 44.8%, 26.8%, 14.1%, and 14% respectively. The respective prevalence for assessed risk factors was: 71.32%, 68.75%, 74.72%, 72.72%, 82.02%, 68.81%, 72.97%, 69.19%, 75.25%, 72.25%, 71.34%, 72.93%, 67.65%, 75.00% Bedele Town, Haro, Ilike Kararo, Obolo Bachara, Cross Breed, Local Breed, Young, Adult, Old, Male, Female, Poor, Medium, and Good, respectively. Only the association between the breed of cattle is statistically significant in terms of the prevalence of ticks (p 0.05). Tick species were highly distributed on the udder part with a prevalence of (26.3%) and least in the vulva body region of the cattle (2.3%). Conclusions: The present study indicated there is a high prevalence of ixodid tick infestation, especially in local cattle breeds, adults, males, poor body condition, and Bedele town. In line with this, further studies on factors affecting tick burden and tick control strategies are recommended. |
