✪ FDA Approves Fenbendazole for Use in Laying Hens to Treat Large Roundworms and Cecal Worms ✪

[casportpony]

I'm not sure how to measure that small of an amount (0.023 ml). This sounds like an earlier-quoted amount of one drop per 5 pounds. If we give the higher dose, how long is the egg withdrawl? Thanks!

0.023 ml is about one drop from a standard syringe. Probably okay to give two drops.

How many chickens do you have? another choice would be to make a mash.

This explains how to make a mash.

If you need help calculating the amount to use, just let me know how many chickens you have and I will do it for you.

I think it's just that they're slow and haven't updated their sites and labels.

The manufacturer does all of the labeling which has to be approved by FDA. They usually get a period of time to allow sale of the old label as long as the labeled use is safe.

To answer your question about small treatment measurements...a tuberculin syringe is a wonderful tool to have. It's a very small syringe that holds 1 ml and it's marked in .01cc increments. Most vet offices will likely carry them. I still have a stash of them from when I worked at a hog barn.

We have 3 chickens, but only 1 is showing signs of worms. I was going to treat her directly. Thank you, this is so helpful!

This struck me......says meat withdrawal...nothing about eggs?
Egg usually hold onto stuff much longer.

That's from FARAD, they are just very slow in updating their website. Fenbendazole at 1 mg/kg for five consecutive days is approved for laying hens.

FARAD includes 'Aquasol', which is the expensive fenbendazole product meant to be added to drinking water. It's fine for laying hens with no egg withdrawal.
I suspect that this particular product made it through testing because the producer was willing to spend the money involved in the testing process; worth it in sales, as opposed to the much smaller 'pet chicken' market, where a few birds are treated individually instead, with already available OTC products.
It makes me comfortable using fenbendazole in my flock if necessary, although it hasn't been needed here ever.

Yes, technically the approved drug is the water soluble one, not the others, but IMO, it doesn't matter.

So it was approved for meat withdrawal previously to Feb 2018, but starting Feb 2018 now also includes eggs?
