This study was conducted in Adaberga dairy farm West Showa Zone, from November, 2014 to April 2015 to evaluate commonly used anthelmintics efficacy against gastrointestinal nematodes. An experimental study design and purposive sampling procedure were employed to select 36 naturally infected jersey breed cattle from source population. And study populations were randomly allocated into three groups, twelve in each; the first group was treated with albendazole, the second with tetraclozan and the last group was left untreated (control). Fecal samples were collected from each cow before and after treatment and modified McMaster method was used to count eggs. Third stage larvae (L3) were recovered from the fecal cultures by the Baerman technique to identify gastrointestinal nematodes. The efficacy of each anthelmintic was determined by Fecal Egg Count Reduction Test (FECRT). SPSS Windows version 16.0 was used for data analysis. Descriptive statistics (means, standard error of mean and reduction percentages) were calculated to manage data. Means were compared among groups through analysis of variance (ANOVA) and difference between treatments was compared using least square method of multiple comparisons. The percentage reduction in mean fecal egg count, after 10 days of treatment, for Albendazole and tetraclozan were 95.51% and 98.18% respectively. There was no statistically significant difference (p=0.262) among the egg count of control, albendazole treated and tetraclozan treated groups before treatment. Statistically egg counts were not different (p=0.85) between treatment groups but there were strict differences (p=0.00) between treatment and control groups on the post-treatment. Generally, these findings indicate that albendazole and tetraclozan are effective against gastrointestinal nematodes in the study area. But, appropriate use of these anthelmintics is credible to prevent future occurrence of resistance.
