A survey was carried out in Bauchi abattoir during the period March 1973 to February 1974 in order to estimate the incidence of bovine fascioliasis. A total of 14,270 cattle originating from various markets in North-eastern Nigeria were examined. The incidence rate varied considerably, the highest being recorded in cattle from markets adjacent to large floodplains. The overall incidence rate was 31-7 per cent. The monthly incidence was highest during the periods immediately before and after the onset of the rains and was more a reflection of the marketing policy of the cattle owners than of the epizootiology of the disease. The annual loss in revenue caused by liver condemnations alone was estimated as 19,375 Naira.
1973年3月至1974年2月期间，在包奇屠宰场进行了一项调查，以估算牛片吸虫病的发病率。共检查了来自尼日利亚东北部各个市场的14270头牛。发病率差异很大，最高发病率出现在毗邻大片洪泛区的市场的牛身上。总体发病率为31.7%。月发病率在雨季开始前后的时间段最高，这更多地反映了牛主人的销售政策，而非该病的动物流行病学情况。仅因肝脏被判不合格造成的年收入损失估计为19375奈拉。
