Evaluation of the persistent activity of moxidectin (10%) long-acting (LA) injectable formulation against Dictyocaulus viviparus, Haemonchus placei, Trichostrongylus axei and Oesophagostomum radiatum infections in cattle

Two controlled studies were conducted to evaluate the persistent efficacy of moxidectin (10%) long-acting (LA) injectable formulation against Dictyocaulus viviparus, Haemonchus placei, Trichostrongylus axei and Oesophagostomum radiatum in cattle. The moxidectin LA injectable formulation was administered as a single subcutaneous injection into the proximal third of the ear at a dose rate of 0.01 ml/kg BW to provide 1.0 mg moxidectin/kg BW. The product had persistent efficacy of >90% against D. viviparus, H. placei and Oe. radiatum for at least 150 days post-treatment and against T. axei for at least 90 days post-treatment.
