A survey of anthelmintic resistance on ten goat farms in the Manawatu region in 1988

Abstract
A survey of anthelmintic resistance on ten goat farms was carried out. The criterion for resistance was a faecal egg coynt reduction (FECR) of Haemonchus, Ostertagia and Trichostrongylus were the resistant genera involved. On none of the ten farms was resistance to oral ivermectin at 0.2mg/kg detected.
