The study was conducted to determine the prevalence of bovine fasciolosis and to assess the effectiveness of commonly used anthelmenthics in Ginner district south-eastern, Ethiopia from September to December 2011. For the determination of the prevalence, 384 fecal samples were collected and examined by sedimentation technique. The result revealed that 121 (31.51%) animals were positive for Fasciola eggs. The infection rate was 30.81 and 32.16% in animals less than four years and greater or equal to 4 years of age, respectively while it was 29.70 and 33.51% in male and female animals, respectively. However, the differences either in age or sex groups were not statistically significant. Anthelmintics efficacy trial was conducted on 45 naturally infected animals. The animals were randomly allocated into five groups. The first group was treated with Tetracloza 3400mg, the second with Albenda QK 2500mg , the third with Albentong 2500mg , the fourth with Ashialben 2500mg, the last group was left untreated (control). Faecal samples were examined before and after treatment (7 days). The percent effectivity for tetracloza 3400mg, albenda QK 2500mg, albentong 2500mg and ashialben 2500mg were 100, 90.91, 57.14 and 62.50%, respectively. In conclusion, fasciolosis is still the most prevalent parasitic disease in the district and anthelmintics commonly used in the district have different efficacy. Strategic control methods have to be designed and implemented. Further wide scale studies using standard products of anthelmintics, are needed to determine the presence of anthelmintic resistance.
