Abstract

ABSTRACT The study was carried out from November 2012 to May 2013 to determine the prevalence of fasciolosis and the economic loss incurred due to liver condemnation in cattle slaughtered at Debre Markos municipal abattoir. From 384 faecal and liver samples tasted, a prevalence of 43.23% and 90.88% was found respectively. There was also an association ( p < 0.05 ) among age and BCS groups of bovine fasciolosis prevalence. According to the intensity of pathological lesions in affected livers, 60 (61.89%) constituted severely affected; the rest, 100 (28.65%) and 33 (9.46%) were moderately and lightly affected respectively. The number of flukes recovered in moderately affected livers was higher (Mean = 90.84) than in either severely (Mean = 33.17) or lightly (Mean = 47.33) affected livers. Species identification revealed that Fasciola hepatica was more prevalent (36.10%) than Fasciola gigantica (1.72%), mixed (1.43%) and unidentified (immature) fluke (3.72%). The average economic loss because of liver condemnation was 13,268,480 Ethiopian Birr (698,341.05 USD) per annum, indicating that the disease has high economic importance. It is therefore concluded that fasciolosis causes significant losses to farmers, butchers and consumers. Finally, the abattoir based prevalence recorded in the study area and the loss incurred suggest that a detailed epidemiological study as well as assessment of the overall economic loss due to fasciolosis is required to implement systematic disease-prevention and control methods.

埃塞俄比亚北部德布雷马科斯市屠宰场牛片形吸虫病的流行和肝脏谴责造成的经济损失
本研究于2012年11月至2013年5月进行,目的是确定在德布雷马科斯市屠宰场屠宰的牛中片形虫病的患病率和肝脏谴责造成的经济损失。384份粪便和肝脏样本中,患病率分别为43.23%和90.88%。牛筋膜虫病患病率在年龄和BCS组之间也有相关性(p < 0.05)。根据病变肝脏病理病变程度,60例(61.89%)为重度病变;中度和轻度感染分别为100例(28.65%)和33例(9.46%)。中度感染肝脏的吸虫数量(平均= 90.84)高于重度感染肝脏(平均= 33.17)和轻度感染肝脏(平均= 47.33)。种类鉴定结果显示,肝片吸虫(36.10%)的流行率高于巨型片吸虫(1.72%)、混合片吸虫(1.43%)和未鉴定(未成熟)吸虫(3.72%)。肝脏谴责造成的平均经济损失为每年13,268,480埃塞俄比亚比尔(698,341.05美元),表明该疾病具有很高的经济重要性。因此得出结论,片形吸虫病给农民、屠夫和消费者造成重大损失。最后,研究区基于屠宰场的流行率记录和造成的损失表明,需要进行详细的流行病学研究以及评估由片形虫病引起的总体经济损失,以实施系统的疾病预防和控制方法。关键词:屠宰场,牛,经济意义,片形虫病
