Abstract
Calves (12) were experimentally inoculated with 6 spp. of gastrointestinal nematodes and the liver fluke, Fasciola hepatica. Six calves were administered albendazole at 10 mg/kg of body wt and the drug efficacy was determined by critical and controlled tests. Albendazole was only 74% effective against Haemonchus contortus (cambendazole-resistant strain), 99 to 100% effective against Ostertagia ostertagi, Trichostrongylus colubriformis, Cooperia oncophora and Oesophagostomum radiatum, and 54% effective against the liver fluke. Except for H. contortus, the critical test provided as accurate a measurement of drug activity against gastrointestinal nematodes as the controlled test provided.
