Bovine fascioliasis is a parasitic disease that affects cattle. It leads to direct and indirect great economic loss due to animal mortalities, growth retardation and expenditure on anthelmintics, reduction livestock productivity and essentially condemnation of infected liver by inspection service. The study was carried out to determine the seasonal prevalence and estimated financial losses of fascioliasis in cattle in the Western Highlands of Cameroon.
A total of 2167 cattle were selected. Later, the cattle, have being the carcasses, were dissected, and the livers were dissected and carefully examined for adult liver flukes. Faeces were collected immediately after the cattle were killed and examined using the formol-ether concentration technique. Condemned livers were weighted to estimate the financial losses using the average price of a kilogram of liver.
A total 428 of cattle were found with infected livers or egg in the faeces giving a total prevalence of 19.75%. Among the infected carcass, 18.64% had both the Fasciola eggs in the faeces and flukes in the liver while 1.10% had only flukes in the liver. Results revealed that prevalence of Fasciola spp. was significantly higher during the rainy season (23.48%) than 16% in the dry season (p = 0.00). A significantly (p = 0.000) higher prevalence was also observed in females (33.9%) than in males (13.1%). Age range showed significant (p = 0.000) influence with the animals of 8-10 years old recorded the highest prevalence of 39.3%. Furthermore, 433.1 kg of liver was condemned giving a direct financial loss of 1221,550 FCFA (2049.64 USD) and an annual financial loss due to liver condemnation estimated to 1814,775 (3045.01 USD).
Findings of this study indicated that bovine fascioliasis is prevalent in cattle in the Western Highlands of Cameroon, and it leads to an important financial loss particularly in the rainy season.
牛 Fascioliasis 是一种寄生虫病，影响牛。由于动物死亡、驱虫支出、牲畜生产力下降以及检查机构基本上谴责受感染的肝脏，它导致了直接和间接的巨大经济损失。本研究旨在确定喀麦隆西部高地牛 fascioliasis 的季节性流行率和估计经济损失。
总共选择了 2167 头牛。后来，这些牛被屠宰，对尸体进行解剖，对肝脏进行解剖并仔细检查成虫肝吸虫。粪便在牛被杀后立即收集，并使用福尔马林-乙醚浓缩技术进行检查。被谴责的肝脏被称重，以使用肝脏每公斤的平均价格来估计经济损失。
共发现 428 头牛的粪便中含有感染的肝脏或卵，总流行率为 19.75%。在感染的尸体中，18.64%的粪便中既有 Fasciola 卵，肝脏中有吸虫，1.10%的肝脏中只有吸虫。结果表明，Fasciola spp.的流行率在雨季（23.48%）显著高于旱季（16%）（p = 0.00）。在女性（33.9%）中也观察到显著（p = 0.000）较高的流行率，而在男性（13.1%）中则较低。年龄范围显示出显著的（p = 0.000）影响，8-10 岁的动物记录了最高的流行率为 39.3%。此外，有 433.1 公斤的肝脏被谴责，直接经济损失为 1221550 非洲法郎（2049.64 美元），每年因肝脏谴责而造成的经济损失估计为 1814775 非洲法郎（3045.01 美元）。
本研究结果表明，牛 Fascioliasis 在喀麦隆西部高地的牛中流行，特别是在雨季会导致重大经济损失。
