| Abstract: | The effectiveness of the new anthelmintic fenbendazole (Panacur) produced by Hoechst, W. Germany, was tested in cattle naturally invaded by gastro-intestinal and pulmonary nematodes. The single dose of 5.7 mg per kg or 7.5 mg per kg body weight administered either in the form of a 10% suspension or in pellets containing 1.5% of the active substance gave 100% intenseffectiveness and 100% extenseffectiveness in the control of Dictyocaulus viviparus, Haemonchus contortus, Trichostrongylus spp., Ostertagia spp., Oesophagostomum spp. and Cooperia spp. The animals tolerated the administration of both drug forms without showing any undesirable symptoms. |
