Actual Correct Dosage for Safeguard Dewormer for Chickens

[dawg53]

Could you do me a favor and point me to the studies on the resistance? I would like to read them.

Here's 47 pages of reading about Ivermectin. The studies are in there somewhere, you can dig through it.

I can tell you from personal experience that I've used Ivermectin in chickens years ago. A couple of my birds were excreting large roundworms. I used Ivermectin pour on them.
About a week later I watched one of treated hens excrete a few live roundworms.

47 pages is a pamphlet to me. Thanks.

Oh 47 pages of forum? I read that wrong assumed it was 47 pages of study. Maybe I'll search elsewhere for it.

Reason I'm interested is simply because the application is different. To me it would make far more sense that Ivermectin being used orally was simply seeing resistence with it's use.

Probably because people were putting low dosage into drinking water as regular maintenance and not because of topical use for mites. But I trust you've read the study.

I think I see the issue now and I believe it's caused by the discrepancy between the amount of fenbendazole per mL vs the amount of liquid per mL.

When converting from mL to mg, you're supposed to multiply by 1000 and the density of the liquid. The density of water is approximately 1g/cm^3 or 1g/mL. So we usually just say that there is 1000mg/mL.

Now the tricky part appears here, at least for me.
In a bottle of Safeguard for cattle/goats, there is 100mg of fenbendazole per mL. BUT this does not mean there is 100mg of LIQUID per mL or does it?

Safeguard dewormer for cattle/goats is a 10% suspension. Meaning only 10% of the stuff inside is the fenbendazole and when you use it, you shake it up and hope the stuff you need had been distributed properly.

Let's say you have the 125mL bottle of dewormer, this technically means there is 12,500mL of fenbendazole in the bottle right?

You can see how this is confusing right?

The amount of liquid and fenbendazole isn't a one to one ratio so when calculating the dosage, a person is asking how much liquid to give per pound of chicken but the answers feel like they're indicating how much fenbendazole to give.

I'm not saying the dosage of ~0.23mL/lb(rounded up tp 0.25mL/lb) is incorrect and as you've mentioned, some worms require a bigger dose. But as I mentioned in my original post, a cow at 100lbs only requires 2.3mL of the liquid which equals to 0.023mL of liquid per pound of cow. Even when a bigger dose is needed, how could it be 10 times more per pound of bird than it is per pound of cow.
In my head, 0.23mL of fenbendazole per pound of bird makes sense but 0.23mL of liquid which should contain 23mg of fendendazole per pound of bird doesn't sound right.

And please by all means, correct me if I'm wrong or misunderstanding anything. I do want to wrap my head around this somehow.

wrong. the suspension is 100mg/ml. if the draw up 1 ml from the bottle in a syringe, it will be 100mg. don't over complicate it. if the high dose for chickens is 20-50mg/kg and make things easy, let's say a chicken weighs 2kg. so it needs to given 40-100mg...so giving it 0.5ml would 50mg, 1ml would 100mg....if the chicken seems sick(lethargic, not eating/drinking, etc)...i use 1ml for a roughly 2kg chicken

Welcome To BYC!

Glad you joined. Thank you for posting.

This thread is almost a year old now and seems to keep going

How many days do I need to give this to my chicken?

for chickens, the dose of fenbendazole to treat ALL worms is 20-50mg/kg for 3-5 days repeated again in 10 days for another 3-5 days

Welcome to BYC.

The 0.23 ml per pound dose (50 mg/kg) is correct if you want to treat *all* worms including capillary worms. Note that egg withdrawal is recommended.


This low dose of 0.00454 ml (1 mg/kg) you are referring to is also correct, but it's for treating large roundworms & cecal worms. It will *not* treat capillary worms, gapeworms, etc.

The correct dose depends on what worms you want to treat.

Thank you for all these charts! Do you know the dose per GALLON of drinking water for all different sized and different breeds of chicks/chickens? (I have too many chicks/chickens/roosters to individually weigh and dose every day for five days and then do it all again 10 days later.)

I’m giving my hens 1ml of the Safeguards for goats for 5 days. For tapeworms. I saw tiny white worms in poop.how long until their poop goes back to normal after 5th dose?

 

[dawg53]

You will need Equimax equine paste or Zimecterin Gold equine paste to treat for tapeworms. The Safeguard liquid goat wormer wont treat tapeworms.
