Abstract:
Hydatidosis is a zoonotic parasitic disease caused by the larval stage of the cestode Echinococcus granulosus. It causes great economic losses in goats and sheep from condemned pluck. A cross-sectional study was therefore conducted from March to April 2015 with the aim of estimating the annual economic loss and evaluating the distribution of hydatidosis in slaughtered goats and sheep with respect to body organs at Amudat slaughter slab, Amudat district. A total of 140 goats and sheep slaughtered were selected randomly in both retrospective and prospective study, this involved review of records, visual, palpation, incisions and weighing of lung, liver and kidney. The proportion of infected organs was analysed using z-test and the distribution of hydatidosis among goats and sheep was analysed using chi-square, meanwhile the annual economic loss was estimated using a formula [(N1 X Ix Cl) + (Nux in X en). The highest distribution of hydatidosis infection (40. O%) was recorded in lung and followed by (20.7%) in the liver while no cyst was recorded in Kidneys. Statistically, the difference between the proportion of the infected lungs and infected liver was significant (p>05)). The distribution of the disease in both goats and sheep was homogenous (p<.05).
The annual economic loss from condemned lung, liver and kidney due to hydatidosis in goats and sheep was estimated at ush 1, 090,009.0($375.9) based on the local market price in the study period. The result of this study reflected that the lungs of goats and sheep were most susceptible. to hydatidosis and condemnation of lungs and liver caused considerable economic loss. Therefore, strategies like dog keeping policies and construction of standard abattoir with disposal facilities would be appropriate to minimize the economic loss associated with the hydatidosis.
