Fasciolosis is a serious animal health problem in Ethiopia where livestock is crucial for the domestic economy. A study was conducted in two Ethiopian abattoirs to estimate the prevalence of infection in goats and sheep, and the monetary losses resulting from liver condemnation. Post-mortem examination of 925 animals (424 sheep and 501 goats) were examined by incision of the liver parenchyma for presence of the liver fluke, . The direct financial losses were calculated based on the estimated prevalence, the market price of the liver, and the average number of sheep and goats slaughtered annually. The overall prevalence of fasciolosis was 10.4% (20.7% sheep and 1.6% goats). Among the studied variables, species of the study animal and age in sheep showed a statistically significant association with infection ( < 0.05). Based on the annual average of 89,054 sheep and 76,374 goats slaughtered, the annual average economic loss due to the condemned liver was estimated at 3700 US$ (185,232 ETH Birr) for sheep and 245 US$ (12,220 ETH Birr) for goats. This study revealed that the prevalence of fasciolosis was higher in sheep than in goats, and substantial economic losses occur for the sheep and goat industry. Hence, considering the irrigations schemes in the country, strategic control programs targeting infection and intermediate hosts are warranted.
在埃塞俄比亚,肝片吸虫病是一个严重的动物健康问题,而牲畜对该国的国内经济至关重要。在埃塞俄比亚的两个屠宰场开展了一项研究,以估计山羊和绵羊的感染率以及肝脏被判不合格造成的经济损失。通过切开肝实质检查925只动物(424只绵羊和501只山羊),以检查是否存在肝吸虫。直接经济损失是根据估计的感染率、肝脏的市场价格以及每年屠宰的绵羊和山羊的平均数量来计算的。肝片吸虫病的总体感染率为10.4%(绵羊为20.7%,山羊为1.6%)。在所研究的变量中,研究动物的种类和绵羊的年龄与感染存在统计学上的显著关联(P<0.05)。根据每年平均屠宰89,054只绵羊和76,374只山羊计算,因肝脏被判不合格造成的年平均经济损失估计为:绵羊3700美元(185,232埃塞俄比亚比尔),山羊245美元(12,220埃塞俄比亚比尔)。这项研究表明,肝片吸虫病在绵羊中的感染率高于山羊,绵羊和山羊产业遭受了巨大的经济损失。因此,考虑到该国的灌溉计划,有必要制定针对感染和中间宿主的战略控制方案。
