Bali cattle (Bos sondaicus) is an indigenous bovine domesticated in Indonesia and harboring prominent genetic traits for livestock production. Parasite infection, however, may act as a large constraint for the husbandry. Bovine coccidiosis is well-known as a major gastrointestinal protozoa which causes a significant loss due to intestinal damage and drug cost. Coccidia wall is derived from thick structures that lead to disinfection difficulties. Furthermore, the tropical climate largely supports its life cycle throughout the year. This study aims to determine the prevalence of coccidia in Bali cattle with an extensive rearing system at Balai Pembibitan Ternak Unggul dan Hijauan Pakan Ternak Denpasar, Indonesia. All of the samples were evaluated using native and flotation method that was followed by descriptive analysis. Deworming is reportedly a routine activity, but no report on anticoccidial treatment. Eimeria spp. were found in 24.19% fecal samples (15/62). The result indicated that coccidiosis is circulated and being observed less compared to worms in the investigated area.
