Abstract

The efficacy of ivermectin administered orally at a dosage rate of 0.2 mg/kg liveweight against naturally acquired larval infestations of Oestrus ovis in sheep was 100% in a field trial. Ten sheep were free from infestation by first, second and third instar larvae of O. ovis 12 days post treatment, whereas 10 control sheep harboured 37.7 larvae on average, most of them first stage.
