Efficacy of fenbendazole against nematodes of captive birds.

Fenbendazole was used to treat nematode infestations (Ascaridia species and Capillaria species) in 230 birds of six orders and 38 different species. Using a single dose of 100 mg/kg bodyweight initial treatment eliminated parasitic nematodes from 221 birds. A further course of treatment at a dose rate of 30 mg/kg daily for seven days eliminated the infestation from the remaining nine birds.
