In the first experiment, 3 groups of 4 calves were experimentally infected with 20 larvae of D. viviparus 7 weeks before moxidectin treatment of 2 of...

Moxidectin, a macrocyclic lactone derived from Streptomyces cyanogriseus, was administered to 12 of 18 calves experimentally infected with D. viviparus as a s.c. injection at 0.2 mg/kg or a pour- on formulation applied to the skin of the back at 0.5 mg/kg. It was highly effective against the adult...

Abstract

The development of trichostrongylid infections was studied in ewes, lambs and tracer lambs grazing a pasture which had been used by calves in the previous year. Treatment with fenbendazole of the ewes two days before they were turned out to pasture virtually prevented infections with...
