Abstract
Survey of economic loss and the prevalence of
Fasciolosis in ovine species were conducted in
Menz Lalo Midir district, Amhara National Regional
State, during the period of September 2010 to June
2011. The objectives of this study were assessing
the financial loss, determining prevalence. The
total of number of study animals were 810 sheep
from eight Kebeles (Tamawenze, Seklaye, Tayate,
Saga, Wegere, Kilerbo, Toll, and Angetla) of Menz
Lalo Midir district selected on lottery system.
Prevalence was determined by fecal sample
examinations. Gross lesions were studied by
postmortem examination where as economic losses
were determined after interview and market
assessment. From fecal examination, the overall
prevalence of ovine fasciolosis was found 70.20%.
The prevalence in male animals was found 50.6% and
in females it was 19.6%. But there exists no
statistical significance between sex groups as the
P value is less than 0.05. During the study period
1,692.00 Ethiopian birr was lost due to
condemnation of liver from 189 animals accounting
74.6 % with 12.00 birr price of a liver.
Clinically, observed signs were emaciation,
weakness, bottle jaw and rough wool. Gross
pathological lesions found were cirrhosis,
fibrosis, and circumscribed pus accumulation,
blunt edges of liver, bile duct hyperplasia and
adult fasciola parasites on section of the liver.
In conclusion, the results of the current study
suggested that ovine fasciolosis was found to be
one of the major disease entities in sheep in Menz
Lalo Midir district.
