Abstract

Fasciolosis is a parasitic plant-born trematodes worm infection caused by the common liver fluke Fasciola hepatica as well as by Fasciola gigantica. The aim of this study was to analyze the bovine fasciolosis and afford various figures about epidemiology, management and control of the disease. A cross-sectional study was accompanied to regulate the prevalence of bovine fasciolosis and ascertain its related risk issues by both coprological and postmortem examination of liver at Sebeta municipal abattoir from November, 2017 to March, 2018. The method includes learning area, study population, study design, sample size and sampling, sampling measures, data managing and investigation. Fasciolosis is a disease causing mortality and production losses mainly in ruminants. Coprological and post-mortem analyses were performed on total of 384 cattle slaughtered in Sebeta municipal abattior. Sex, age, breed, body condition score and origin of animals were taken into attention as risk factors. Fecal examination, followed by liver incision, surveillance and species ID on the basis of size and morphology of adult worm were functional. An outside total prevalence of 18.5% (71) and 22.4% (86) were found on the basis of coprological and post-mortem examinations, respectively. The percentage agreement between the two diagnostic methods was 82.56%. However, post-mortem examination of infected livers was better for diagnosis of fasciolosis in slaughtered animals as early infection can also be diagnosed. Among the possible risk factors associated with fasciolosis, only sex and origin of the animals did not show significant variation (p > 0.05). However, age, body condition and breed of the cattle was important (χ2 =5.666a p=.017, χ2=98.603a p=.000 χ2=8.891a p=.003) respectively, which show significant variation between them. From the finding, the dominant species in the revision area was F. hepatica (44.2%), while F. gigantica and mixed infection were recorded in 36.0% and 18.8%, respectively. The study specifies that the infection occurrence of fasciolosis was based on body condition of animals, age and breed of animals, but origin and sex of animals have little importance on prevalence of fasciolosis. Appropriate ante mortem, postmortem assessment and snail control methods are recommended for control measures.
