What is the dosage for fenbendazole?

Oh goodness, and a harsh antibiotic at that! All the fluoroquinolones are quite invasive, broad-spectrum antibiotics, and have some harsh side effects, from random tendon snapping (last I checked, doctors were not sure why that happens), to severe gastric distress and abnormal liver enzymes. And you'll definitely have to toss eggs for a while with that one, because it has a very long residual effect and almost complete tissue permeability, and will surely find its way into your girl's eggs! I worked as a vet tech for 10 years, and it was something we prescribed only for the worst of the worst infections, especially food animals. And it's banned for poultry use, since about 9 or 10 years ago. We could not prescribe or administer it legally to chickens at our practice.
Believe me, Baytril is not something you want to administer casually.

Often it's the best choice for *very* sick birds, especially if something like E. coli is suspected.

Panacur AquaSol is also used for the treatment of two types of roundworm infections in the gut of chickens:

Ascaridia galli (L5 and adult stages);
Heterakis gallinarum (L5 and adult stages).


For chickens, Panacur AquaSol is added to their drinking water in a quantity that aims to supply each chicken 1 mg fenbendazole per kg bodyweight daily; this is done for five consecutive days.

The withdrawal period for chicken meat and offal is six days and for eggs it is zero days

Sorry it's cut and paste. The original also discusses use in pigs. This particular product is added to drinking water but the important parts are dosage, length of treatment time and withdrawal periods.

We don't have panacur aquasol here as far as I know...never heard of it.
Here, panacur is 10% fenbendazole as mentioned earlier. The paste is not soluable in water. The 10% liquid does not mix well in water and settles at the bottom of the container rendering it ineffective unless stirred often. I've used both many times...it's best to give the liquid orally undiluted to each chicken using a syringe without a needle. That way there is no guesswork whether a bird has been properly dosed or not.
Panacur aka fenbendazole kills more types of worms than just large roundworms (ascardia galli) and cecal worms (heterakis gallinarum.) Most worms that infect chickens in general ARE types of roundworms except cestodes and trematodes. In the case of the latter, albendazole is the wormer of choice that kills all known worms that chickens can get.

To the best of my knowledge, 1mg/kg won't be effective in poultry even if given for five days. Maybe it's a typo?

They came up with water soluable fenbendazole. How about that? It would be good for a large flock. But there's no guarantee birds will drink enough of it over a 3 day period to be effective. Then if there are sick birds due to worm infestation, they wont drink at all. It's still better to give it orally to each chicken.

at that rate it would be 200mg/kg, and that seems like a heck of a lot more than 50mg/kg.
If they really meant to dose at 1mL/kg...which is probably what that person meant?

Kathy is the math whiz, she can figure it out lol. I'm not into the mg/kg stuff. I keep it simple using the liquid goat wormer: 1ml for giants, 3/4ml for large fowl, 1/2cc for standards, 1/4cc for small birds. Yeah I know, ml and cc are the same. No problem.

Quote: If that's what they meant, then yes, that would be 200mg/kg and way too much according to everything I have read.

Very cool product, but I'll stick to giving ot orally.
