Removal of Haemonchus contortus, Ostertagia circumcincta and Trichostrongylus spp. from goats, by morantel citrate, levamisole hydrochloride, fenbendazole, and oxfendazole
Young feral goats harbouring 3, 7 and 36 day old experimental infections of strains of gastrointestinal nematodes, known to be susceptible to anthelmintics in sheep, were dosed orally with commercially available anthelmintics at the manufacturers` recommended rates for sheep. The drugs and overall removals of Ostertagia circumcincta and Trichostrongylus spp. (T. colubriformis and T. vitrinus) respectively were: morantel citrate 69% and 68%; levamisole hydrochloride 55% and >99%; fenbendazole 98.5% and >99%; oxfendazole >99% and >99%. Results for Haemonchus contortus, while not inconsistent with high efficacy for all four drugs, must be interpreted with caution, in view of the erratic establishment of this worm in the controls.
