Prevalence of Bovine Fasciolosis in Municipal Abattoir of Haramaya, Ethiopia

Abstract

A cross sectional study was carried out from November, 2013 to March, 2014 with the aims of determining the abattoir prevalence and direct economic loss associated with fasciolosis in cattle at Haramaya municipal abattoir, Ethiopia. From the total of 480 examined cattle, 117 (24.4%) were found to be positive for fasciolosis by postmortem liver inspection. From 117 infected livers with Fasciola species, Fasciola hepatica was found to be the most prevalent species 69(58.974%) and Fasciola gigantic, and mixed infection were proved to be 30(25.64%) and 18(15.38%), respectively. Highest prevalence of fasciolosis was observed in poor body condition cattle 50(64.1%) followed by medium 40(38.84%) and good body condition cattle 27(9.03%), respectively. Statistical analysis of the data showed the presence of statistical significant difference (P<0.05) on the prevalence of fasciolosis among the different body condition scores. There was also a statistically significant difference (P<0.05) in the prevalence of bovine fasciolosis in different age groups considered. The highest 50(73.5%) prevalence was in young animals and the lowest 67(16.3%) was found in adult animals. The prevalence of bovine fasciolosis was highest 71(30.9%) in Haramaya area than Kersa 38(26.7%) and Dawe 8(7.4%) with statistically significant difference (P<0.05) in the prevalence of bovine fasciolosis was observed. Analysis of the abattoir data indicated a total annual liver condemnation which resulted in 86, 083.2 Ethiopian birr (4414.523 USD) loss. The results of the present survey showed that the prevalence and monetary loss of fasciolosis in cattle slaughtered at Haramaya municipal abattoir was high and warrants immediate need for prevention and control of the parasite in the study area in particular and in the country at large.
