Abstract
A cross
sectional study was conducted from October 2010 to
March 2011 to assess the prevalence, cyst
viability, organ distribution and financial losses
of bovine hydatidosis in cattle slaughtered at
Dessie municipal abattoir. Postmortem inspection,
cyst characterization and financial loss
estimations were conducted. Out of 610 inspected
cattle, 83 (13.61%) were harbouring a single or
multiple hydatid cysts. Significantly (P<0.05)
higher infection rate was observed in poor
(22.89%) than medium (12.99%) and good (10.40%)
body condition scorings but significant variation
(P>0.05) was not observed in different age groups.
Anatomically, the cysts were distributed 68.67% in
the lung, 14.46% in the liver, 6.02% in the
kidneys, 1.2% in the heart and 9.64% were found
both in the lung and liver. Of the total examined
cysts (195) for fertility and viability, 27
(13.85%) were fertile, 44 (22.56%) were calcified,
124 (63.59%) were sterile. The rate of cyst
calcification was higher in the liver (78.14%)
than other organs whilst the fertility percentage
was higher in the lung (14.65%). Of the total 27
fertile cysts subjected to viability test, 13
(6.67%) were viable. Size assessment made on 195
cysts indicated that 153 (78.46%) were small, 41
(21.03%) were medium and one (0.51%) were large
sized cysts. In the present study, the total
annual economic loss from organ condemnation and
carcass weight loss due to hydatidosis was
estimated as 681,333.87 Ethiopian birr which is
about 39157.12 United States dollar per annum
based on the local market prices in the study
period. The result of this study revealed that
hydatidosis is an economically important disease
of cattle which necessitates designing of
appropriate strategies for its control.
