[The effectiveness of the drugs Dovenix and Bilevon(R)-Injection against liver fascioliasis (Fasciola hepatica, Linné 1758) in cattle].

Dovenix and Bilevon-injection (manufactured by SPECIA, France and BAYER, West Germany, respectively) were tested for their anthelmintic efficacy against Fasciola hepatica in cattle. The drugs proved highly effective against both adult and immature flukes. The faeces of the treated animals were negative for F. hepatica eggs when examined 91 days after the treatment. In experiments with rats Dovenix and Bilevon-injection were tolerated up to eight times and ten times higher doses than the normal therapeutic dose, respectively.
