Effect of albendazole on gastrointestinal parasites of cattle.
The efficacy of albendazole in removing gastrointestinal nematodes and tapeworms was studied in 16 treated and 16 untreated (control) beef calves. The anthelmintic was administered as an oral drench at a dose level of 5 ml/45.5 kg of body weight (5 mg/kg). Percentage of efficacy against the various genera was: Trichostrongylus axei, Oesophagostomum radiatum, and Moniezia-100.0; Haemonchus placei, Cooperia spp, and Trichostrongylus colubriformis - greater than 99.0; Ostertagia ostertagi -98.3; and Bunostomum phlebotomum -96.2. Efficacy against Trichuris was 20.2. Efficacy against immature nematodes in the abomasum and small intestine was high, 91.9 and 86.4, respectively, but total numbers of nematodes were not large. Efficacy against immature stages in the cecum and remainder of the large intestine was 48.5. Signs of toxicosis were not observed in calves treated with albendazole.
