Infection of livestock with Fasciola hepatica is a worldwide, economically important and increasing problem. Even though, bovine fasciolosis can be a disease associated with particular regions, there are usually epidemiological issues on individual farms. For this reason, it is recommended to find the source of infection by examination of definite hosts and pastures on a farm. The following factors which promote the transmission of bovine fasciolosis are usually found: (A) Snail habitats are present on pastures used for young stock (prior to first calving) or dry cows only. Pastures for dairy cows are not affected. (B) Snail habitats are present on all pastures for dairy cows. (C) Snail habitats are present on single pastures used for dairy cows. (D) Snail habitats are present on hayfields. For each of these epidemiological situations an individual control strategy is advised. When a control strategy is tailored according to the specific epidemiology found on the individual farm, egg shedding and F. hepatica-seroprevalence can be reduced significantly. This approach can support the responsible use of the available flukicides.
家畜感染肝片吸虫是一个全球性的、具有重要经济意义且日益严重的问题。尽管牛片形吸虫病可能是与特定地区相关的疾病，但在各个农场通常都存在流行病学问题。因此，建议通过检查农场中的终末宿主和牧场来寻找感染源。通常会发现以下促进牛片形吸虫病传播的因素：(A) 在仅用于幼畜（首次产犊前）或干奶牛的牧场上存在蜗牛栖息地。奶牛牧场不受影响。(B) 在所有奶牛牧场上都存在蜗牛栖息地。(C) 在用于奶牛的单个牧场上存在蜗牛栖息地。(D) 在干草地上存在蜗牛栖息地。针对这些流行病学情况中的每一种，都建议采取单独的控制策略。当根据各个农场发现的特定流行病学情况量身定制控制策略时，虫卵排出和肝片吸虫血清阳性率可显著降低。这种方法有助于合理使用现有的杀吸虫剂。
