A study of a strategic dosing programme against ovine fascioliasis on a hill farm
In a farm-scale veterinary preventive programme run from 1973 to 1976 the use of rafoxanide (Flukanide; Merck Sharp & Dohme) in the prophylaxis of ovine fascioliasis resulted in a marked reduction in the percentage of ewes passing fluke eggs in the faeces and an absence of clinical cases of fascioliasis throughout these years. Three separate flocks of hill sheep were used in this study in which the aim of the dosing programme followed was to kill the majority of liver flukes (Fasciola hepatica) before they reached adult egg laying stage, thereby eliminating, or considerably reducing, the number of eggs passed on to the pasture.
