Efficacy of moxidectin against multiple resistant Ostertagia spp. in lambs.
Moxidectin was demonstrated to have a high efficacy in lambs against Ostertagia spp. which were resistant to albendazole, levamisole and ivermectin in goats. Moxidectin reduced the number of eggs in faeces by 99.6% and the number of worms found at post-mortem dissection of the lambs by 99.9%. Of the adult worms found in abomasa, 91% were identified as Ostertagia circumcincta and 9% as Ostertagia trifurcata.
