Abstract
Fasciolosis is a serious animal health problem in Ethiopia where cattle raising is very important to the local economy. A cross sectional study was carried out from November 2018 to February 2019 to estimate the prevalence of bovine fasciolosis and its associated risk factors as well as financial losses due to liver condemnation. A total of 247 cattle consisting of 219 males and 28 females were randomly selected and fecal sample collection for Fasciola egg detection and postmortem liver inspection for adult liver flukes, were done. From the total of 247 cattle examined, the overall prevalence of bovine fasciolosis in the study area was 16.6% and 20.24% by coprological and postmortem examinations, respectively. The livers and bile ducts were examined for the adult flukes and the result showed that F. hepatica was frequently detected Fasciola sp. (72%) than F. gigantica (28%). In the study area, the prevalence of bovine fasciolosis between sex was significantly different (p < 0.05) with higher prevalence was recorded in female (57.1%) than male (15.5%). There was also significant association (p < 0.05) among different age groups for the prevalence of bovine fasciolosis with the highest prevalence in older (40.1%) than younger (18.8%) age groups. But, regarding origin and body condition the prevalence of bovine fasciolosis was not significantly associated (p > 0.05). The annual direct financial losses incurred due to fasciolosis were estimated around 1,505, 856 ETB ($43, 024.458). In conclusion, bovine fasciolosis is prevalent and economically important disease in the study area. Therefore, implementation of control and prevention strategy like, grazing managements, reducing the population of the intermediate host, diagnosis and treating sick animals using anthelmintic, is mandatory.
Highlights
Fasciolosis is a major problem that a ects the productivity of livestock throughout the world [1, 2]
F. hepatica found in temperate areas and in cooler areas of high altitude in the tropics and sub tropics, whereas F. gigantica which predominates in tropical areas [4]
Fasciolosis is commonly distributed in countries where cattle and sheep are raised and there is a niche for Lymnaeid snail and the disease repeatedly reported in di erent continent such as America, Australia, Europe, Asia and Africa [5]
Summary
Fasciolosis is a major problem that a ects the productivity of livestock throughout the world [1, 2] It is caused by the genus Fasciola which is commonly referred to as liver ukes [3]. In Ethiopia bovine fasciolosis is a widely distributed disease which imposes economic impact on livestock production of cattle and sheep [10]. According to study reported by di erent researchers, the economic loss associated with a ected liver condemnation due to fasciolosis in di erent area of Ethiopia is ranging from 86, 083.2 ETB ($2459.52) to 1,751,432 ETB ($50040.91) [12,13,14]. Ough there fasciolosis, is economically important disease there is scarcity of well-documented information on the occurrence of fasciolosis and nancial loss associated with liver condemnation among cattle in Wolaita soddo, Ethiopia. Since epidemiology of fasciolosis is dynamic and may change with years [18] and the price of liver varies with years, it is important to monitor its development to determine trends in prevalence and estimate nancial loss associated with liver condemnation, due to fasciolosis. ough there fasciolosis, is economically important disease there is scarcity of well-documented information on the occurrence of fasciolosis and nancial loss associated with liver condemnation among cattle in Wolaita soddo, Ethiopia. erefore the aim of this study was to determine the current prevalence of bovine fasciolosis and its associated risk factors as well as nancial losses due to liver condemnation
