Controlled trials of the anthelmintic oxfendazole in ewes and lambs naturally infected with gastrointestinal nematodes.
Oxfendazole doses at a rate of 5 mg per kg, before or after lambing, reduced nematode egg output to insignificant levels in ewes, most of which were not exposed to re-infection. Ewes treated with oxfendazole had a significantly lower egg output than those treated with levamisole, although the latter anthelmintic was also highly effective. In lambs, oxfendazole at a dose rate of 5 mg per kg, showed 100 per cent efficacy for Ostertagia circumcincta, O trifurcata, Teledorsagia davtiani, Trichostrongylus axei, T vitrinus, T colubriformis, Nematodirus battus, N filicollis, immature Nematodirus, Chabertia ovina, and 93 per cent efficacy for Trichuris spp. Levamisole showed similar efficacies but did not remove Trichuris.
