Prevalence of Major Bovine Trematodes (Fasciola and Paramphistomum) in Cattle Slaughtered at Nekemte Municipal Abattoir, East Wollega, Oromia Regional State, Ethiopia

摘要

A cross-sectional study was conducted from November, 2015 to April, 2016 to determine the prevalence of major trematodes ( fasciolosis and paramphistomosis) and the associated risk factors in cattle slaughtered at Nekemte municipal abattoir, East Wollega Zone, Oromia, Ethiopia. From a total of 400 animals selected by systemic random sampling at postmortem, prevalence of fasciolosis and paramphistomosis was 19% and 41.5%, respectively.The prevalence of fasciolosis was 19.02% and 18.87%, and paramphistomosis was42.07% and 37.74% in male and female animals, respectively.There was no statistically significant association of bovine fasciolosis and paramphistomosis between sexes (p0.05).Fasciolosis was higher in old age(19.02%) than adult age (18.84%). Infection rate of fasciolosis and paramphistomosis for cattle with poor body condition was (29.27% and 53.66%) with medium (18.46% and 40.77%) and good body condition (14.89% and 36.70%), respectively. This result also showed that difference of the prevalence among the different body condition was statistically significant (P0.05). The prevalence of ,F. gigantica, mixed and immature ones was, 40.8%, 22.4%, 19.7%, and 17.1%, respectively with highest prevalence observed in F. hepatica . In view of current result, trematodes are major obstacles for livestock production and productivity by remarkable direct and indirect losses. Hence,control strategies targeted on the parasite and the intermediate host as well as management system in the study area is warranted.
