Fenbendazole (brand names Panacur® and Safe-Guard®) is a benzimidazole anthelmintic used ‘off label’ to treat a variety of intestinal parasites (e.g., roundworms, flukes, certain types of tapeworms, and Giardia) in pet poultry. Fenbendazole can be administered to each chicken orally by syringe, or added the flock’s drinking water source. Fenbendazole may not be effective against Capillaria spp. Fenbendazole is absorbed in the intestine, and is rapidly metabolized by the liver. The metabolic pathway of fenbendazole in chickens is the same as in mammals. Fenbendazole is eliminated from the body predominately by the feces. Residue levels in the eggs is highest the first day following the last day of treatment, and decline rapidly thereafter. Fenbendazole must be given for 3-5 consecutive days to kill parasites, since it needs to halt cell division for a certain duration before it is fatal to the parasite.
With the increasing number of free-range domestic chickens, helminth parasites have potentially become more of a threat to commercial flocks in recent years, and routine poultry deworming is needed to improve the efficiency of chicken production. The present study deals with a field trial to study the efficacy of two generally used anthelmintics, fenbendazole and levamisole, against gastrointestinal nematodes of domestic chickens in northern Iran.
Features of Fenbendazole For Chickens
I have used Fenbendazole for years and you would need to mix the 1 mil (one dropper line for 6-10 chickens including the rooster) in plain yogurt( 1/2 cup) or cottage cheese! I back off 10 days with feeding eggs to anyone that is not family! This is a type of dewormer product and is used in low dosage for chickens . The eggs will have trace amounts but if you cook them well any parasite or med would be rendered inert! I would not eat eggs for 3 days after initial treatment if you want to avoid the parasite even if inert! You will treat them with this for 3-5 days depending on number of chickens and severity of infestation. I also recommend DE flour (diatomaceous earth) which slices the vertebrae of parasite(kills them precisely). Dust the coop and the pen where they eliminate regularly which is the cause of parasites. DE can be purchased in 50 pound bags and last for 3-5 years . It is a cheaper way to go. A bottle of Safegard (fenbendazole) goes for 20 bucks and lasts a long time! Clean the coop regularly (depending on number of chickens) DE is also great for most livestock! chickens will roll and dust themselves with it to kill parasites!If you do these steps you should have happy healthy friendly chickens and eggs!
Uses/benefits of Fenbendazole For Chickens
Fenbendazole is a non-FDA approved, off label treatment for roundworms, capillary worms, cecal worms, tapeworms, flukes and gapeworms. It can be given orally, in drinking water, and the paste can be given in pea-sized doses. You may also mix a medicated solution in with feed. The Food Animal Residue Avoidance Databank notes an egg withdrawal period of 17 days and meat withdrawal of 6 days Fenbendazole is sold as Panacur, Safe-Guard and Fish Bendazole.Fenbendazole can easily be given as a feed additive to treat the entire flock in one day. I have personally used this with success for tapeworms. You’ll want to purchase the 10% suspension (liquid) Safe-Guard for goats.
For ducks: 5-15 mg/kg given orally, once a day for 5 days.
For chickens: 20-50 mg/kg given orally for 3 to 5 days, repeated again for another 3-5 days in 10 days.
