Abstract

Different therapeutic regimes using flubendazole for the treatment of Trichostrongylus tenuis infection in experimentally infected grey partridges Perdix perdix were examined. Flubendazole dosages of 4, 8 and 20 mg/kg were administered orally as a single dose or split into 3 or 9 parts given over 9 days. The efficacy against adult worms in the caeca improved with dose rate. Split doses were at least as effective as single doses, which removed up to 83% of adult T. tenuis. A dose of 20 mg/kg administered on a daily basis over 3 or 9 days gave the best clearance of T. tenuis, resulting in a reduction of at least 95% in worm burden.
