Paramphistomosis is one of the most important emerging rumen flukes affecting Ruminates worldwide. The infection is worst in tropical and sub-tropical regions Due to perceive little or no attention in Ethiopia because of the misbelief that it does not cause disease in animals. However, this infection causes substantial economic losses to the livestock. The general objective of this study is to determine the prevalence of bovine paramphistomosis and its associated factor in Debre Tabor municipal abattoir. Across-sectional studies were conducted by using systematic random sampling of apparently healthy animals to determine the prevalence of paramphistomosis and its associated factors. 384 animals were sampled in the study period. Animal’s examined by the routine abattoir inspection methods of antemortem and postmortem examination to detect adult Paramphistomum and their effect on the fore stomach. Data collected, entered, cleaned, and recorded were made by Microsoft Excel spreadsheet. All statistical analyses were done using statistical software for social science (SPSS). A probability (P) value less than 0.05 was set as statistically significant. The overall prevalence of paramphistomosis in debretabor municipal abattoirs was 167(43.4). From the total of 384 bovines examined in the abattoir, 167 animals were infested with paramphistomum, while the rest were negative. The prevalence of paramphistomosis based on origin and age group was statistically significant (P-value less than 0.05) (p=0.000). (p=0.01) respectively. Paramphistomosis was found prevalent in the study areas. Those had been a hindrance to livestock production by causing remarkable direct or indirect effects on livestock’s in the study area, even though it needs to develop integrated control, prevention, and awareness creation strategies in the community for the control of paramphistomosis
