WORMING with Fenbendazole - - How much?

[math ace]

I swear the older I get the more I forget. I wormed my birds 6 months ago with Fenbendazole (safe-gaurd). DUH, I didn't write the dosage on the bottle and NOW I can't remember how much to use.

IT is 10% suspension Fenbendazole meant for deworming goats. I like to put it in a gallon of water.

Does anybody remember how much to use in a gallon of water ? ?


Last time, I think, I put it in their water for 2 days and then waited 10 days and repeated. Does this sound right ? ? ?


Is it necessary to repeat a second dosage this time IF I already wormed with wazine 10 days ago ? ?

Hi math ace, I pretty much know most of the dosages for different wormers. Fenbendazole 10% suspension liquid goat wormer, kills gapeworm too....3cc/ml per gallon of water. The fenbendazole paste equine wormer is "pea" size amount for each chicken. BTW; no need to reworm again after using the goat wormer since you used the wazine as your 1st wormer.

Equimax or something containing praziquantel would be my choice to treat tapes. Can you post a picture of the praziquantel sold in Canada so I can verify that it's the same as the stuff sold here? The stuff sold in AU is different, so that why I'm asking.

The most important place on a chicken to inspect for external parasites is around the vent area where it's warm and moist.

I think this is always a good place to check, but several species of lice live on different parts of the body. I always check legs, vent, back, wings, belly, neck and head.

There's no need to use a miteacide if you dont see external parasites.

Would it surprise you to know that I have checked a few and found no bugs, but threated them anyway. I then placed them in a box on paper towels and came back 30 minutes later to find tons of dead lice.

Hey Rancher Hicks - - is it coffee time already ? ? ?

It has been around for many years. It is the same medicine that is in either Safe-gaurd or Panacur. You can find it at most feed stores including Tractor Supply. It comes in paste, pellets, or liquid.

I tried the pellets, but the chickens didn't like it and they had to eat a lot of it. The liquid treatment is painless to the birds and me.

I think most wormers have a egg withdrawal period. Wazine is the only one who specifically says for chickens and prints their withdrawal period. For most wormers, including safegaurd, the withdrawal period is 10 - 14 days. I think the purpose of the withdrawal period is to prevent somebody from having an allergic reaction to any worming residue that might be passed on thru the eggs. SOME BYC folks ignore the withdrawal period because they do not sell eggs to the public. I, on the otherhand, have family members who are allergic to all kinds of strange things - - - so I honor the withdrawal periods.

It killed me to have to buy eggs yesterday for our own use !

OK eveybody else, remind me of how much of this stuff I need to put in their drinking water . . . . . .

Verm-X is advertized in BY poultry and has no withdrawl period. It does say to use monthly and is expensive at that rate. I figure there has to be a better way. I doubt the birds would get infected in the winter if they are clean going into it. So that gives me 6 months here in NY.

Still I won't stop til I find a better way.

The UK advertises a wormer with no withdraw but I don't know if I can order it from here. I wonder if I can get it in Canada. Flubenvet I think it's called.

I wonder if there is something safe to spread in the yard to kill parasites or reduce their numbers that is safe for the birds.

When you mix liquid fenbendazole with water be sure to shake/stir the water a few times each day. The fenbendazole is thick and heavy, will sink to the bottom of the bowl or container. You really want a fairly consistent suspension in the water to get good coverage. I tend to keep some 2 liter bottles around when I worm my birds. And I mix a couple up a few times each day, and then go out and re-fill the water bowls. There is quite a bit of waste. But unless you have tons of birds the bottle of goat wormer will last you for years.

I just got a pm from another BYC member who spoke to a poultry vet from her state.

He recommend a 2.25 ml dosage in a gallon of water for 3 days. Fenbendazole is a safe wormer that is very hard to overdose on. This being said, I think today I will start my birds on a 3 ml dosage and do the 3 day dosage.

My birds are going to be so mad! That means 3 days without free ranging. I don't plan on doing it a second time since I already did the wazine 11 days ago.

I like what briteday recommended - - - Shake, Shake, Shake your bottle - - you can do
Oh no, I think I just had a disco flash back

I purposely postponed the worming til today, so that I can shake up the water every couple of hours , , , ,
Lordy, I think my girls are surrounded with

and they don't even know it !

Thanks for all the help. . .

You sound experienced - you're certain it was a roundworm - not a tape? Because the treatment would be different? I just want to "dot my i's and cross my t's" here.

It wasn't flat and segmented, but thin and round?

Piperazine's (Wazine) mechanism of action is indeed that it paralyzes the worm, causing it to be expelled. Roundworms do not live for very long outside their host. So you need not be concerned about having to retrieve them. But that's one reason why I follow up with something that DOES kill them.

They do also excyst and travel, as larvae, to the lungs of the animal at one point in their development. From there they are coughed back up and reenter the digestive tract where they become adults. There they are treatable by all roundworm-effective antihelmintics. You likely know this, but this is more for someone else who might read this and not know.

If you see a bird passing a worm, it's more likely that they have a large infestation since (as you well know) you will otherwise rarely see worms in poultry. So really, unless you do a fecal egg count to show how many eggs are being shed, one must assume there COULD be a large number of worms both in the intestines and the lungs.

If you kill all of the roundworms at once, then you have these dead worms that need to be expelled. If a bird's body is presented with a high number of dead worms, they can sometimes have an anaphylactic reaction to what has essentially become a "foreign protein" in their body. Alternately, there have been cases where a large number of dead worms being expelled from the body have caused blockage.

So that's why I always recommend Wazine first. If there are a large number of roundworms (and again we have to assume it's possible unless proven otherwise by an egg count), then you won't risk the "dead worm" foreign protein effect. Because Wazine is a repeated wormer, it's less effective and you won't overload the bird with passing worms if there's a huge infestation. If there are few, you might just get them all. But it's meant to be repeated.

Instead of repeating the wazine, I like the more broad spectrum wormers that also effect cecal worms, and even external parasites, and actually paralyze as well as KILL the parasites. I'm not sure whether or not it works on the lung parasites, and would suppose it depends on the wormer. Personally I use pour-on ivermectin which doesn't go through the digestive system but through the tissues. So it would be most likely to do so. I'm looking that up now actually because I don't know. It says "immature" but I'm not sure they mean in the lungs, though I really think they do.

But since ivermectin (and fenbendazole, and levamisole, and other broad-spectrum wormers) DO kill a number of other parasites (that may not shed through the feces) I like to knock down the numbers first with wazine. Also because ivermectin kills adult and immature roundworms, I take the safe gamble and do the weaker treatment first. Then go back and blast both adult and immature worms.

I hope that makes sense.
