title: Evaluation of four forms of oxfendazole against nematodes of cattle.
abstract: Oxfendazole, methyl [5-(phenylsulfinyl)-1H-benzimidazol-2-yl] carbamate, was evaluated in calves naturally infected with endoparasites. The compound was used as a drench, a paste, a bolus, and as top-dress crumbles at a dosage of 2.5 mg/kg of body weight. The four formulations produced similar effects and were 99% to 100% effective in removing the following adult parasite genera: Haemonchus, Ostertagia, Trichostrongylus. Cooperia, Bunostomum, Oesophagostomum, and Dictyocaulus. Mean efficacy against Trichuris spp varied from 87% to 95%, depending on the formulation used.
