Study on the Prevalence of Bovine Fasciolosis and Estimated Financial Losses Due to Liver Condemnation: Incase of Angacha Woreda, Kambata Tembaro Zone, Southern Ethiopia

摘要

A cross sectional study was carried out from December, 2015 to June, 2016 with the aims of determining the abattoir prevalence and direct economic loss associated with fasciolosis in cattle at Angacha municipal abattoir, Ethiopia. From a total of 384 examined cattle, 156 (40.62%) were found to be positive for fasciolosis by postmortem liver inspection. From 156 infected livers with Fasciola species, Fasciola hepatica was found to be the most prevalent species 120 (47%) and Fasciola gigantic and mixed infection were proved to be 26 (25.64%) and 10 (17.34%), respectively. Highest prevalence of fasciolosis was observed in poor body condition cattle 104 (43.3%) followed by medium 40 (38.84%) and medium body condition cattle 52 (36.10%), 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 119 (42.5%) prevalence was in adult animals and the lowest 37 (35.57%) was found in young animals. The prevalence of bovine fasciolosis was highest 62(48.43%) in Jaba than Doyo gena 48 (37.5%) and Shino 46 (35.93%) 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 48,744.00ETB Ethiopian birr loss. The results of the present survey showed that the prevalence and monetary loss of fasciolosis in cattle slaughtered at Angacha 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.
