Flubendazole: safety regarding egg production and reproductive performance of breeder chickens.

In a comparative field trial, 5,950 meat breeder chickens were medicated via feed for 7 consecutive days with 60 ppm of the anthelmintic flubendazole. This treatment cured the birds of an infection with Ascaridia galli and Capillaria obsignata. A slight but transitory diarrhea was observed in treated chickens. The applied medication did not unfavorably affect egg production, fertility, or hatchability.
