Efficacy of moxidectin against gastrointestinal nematodes in naturally infected lambs and calves

Abstract

In this trial based on the reduction of the egg output and on the evaluation of results from larval/egg differentiation, moxidectin (Cydectin, 1% injectable moxidectin) administrated subcutaneously ata dose of 0.2 mg kgbw(-1) was found effective on the gastrointestinal nematodes in naturally infected lambs (8 female and 7 male treatment; 8 female and 7 male control) harbored Haemonchus spp, Ostertagia spp, Trichostrongylus spp and Nematodirus spp and in naturally infected female carves (20 treatment and 10 control) harbored Haemonchus spp, Ostertagia spp, Trichostrongylus spp, Bunostomum spp and Cooperia spp. The efficacy was 100% on day +7, 99.9% on day +14 and 100% on day +28 in lambs and 100% on day +7, 99.9% on day +14 and 98.9% on day +28 in carves.
