title: Dose-titration of fenbendazole in the treatment of poultry nematodiasis.
abstract: Broiler chickens were fed ad libitum diets containing fenbendazole at various concentrations and durations for the removal of adult Ascaridia galli, Heterakis gallinarum, and Capillaria obsignata. All regimens were 100% effective against A. galli. Fenbendazole at doses of 80 ppm for 3 days and 48 or 30 ppm for 5 days was 100% effective against H. gallinarum. C. obsignata was not removed completely by any regimen, but greater than or equal to 95% effectiveness was seen in birds given fenbendazole at doses of 80 ppm for 3 days and 48 ppm for 5 days. All medicated rations were readily consumed, and the treated birds exhibited no adverse reactions.
