Prevalence of Bovine fasciolosisinfectionin Hossana municipal abattoir, Southern Ethiopia

Abstract

A cross-sectional study was carried out from November 2013 to June 2014 to determine the overall abattoir based prevalence of fasciolosis infection, and to assess direct economic loss due to liver condemnation. Postmortem examination and abattoir retrospective data were retrieved and analyzed.  A total of 422 cattle were selected randomly and examined during the study period. The prevalence rate of fasciolosis was foundto be 27.25% (115). Age, species and body condition score were taken into consideration, whereby 34.67and 20.62% prevalence were recorded for young and adult animals, respectively. Similarly, 57.30, 19.89, and 18.25 % prevalence have been registered for poor, medium and good body condition score, respectively. Also, the dominant Fasciola species showed50.58, 29.57, 14.78 and 6.09% prevalence for F. hepatica, F. gigantica, mixed infection and immature species, respectively. There was a significant difference at (P < 0.05) value among age, body condition scores and species, and between coprological and postmortem examination (P= 0.00). Depending on the current local price of a liver, the total annual financial loss encountered due to the condemnation of infected liver to fasciolosis was estimated to be 66,370.10 ETB or 3,493.16 USD. The result of the study confirmed that bovine fasciolosis infection was found to be one of the major diseases and brings a significant economic loss in Hossana municipal abattoir.
