Ivermectin 1% Injectable Question

Welcome to BYC!​

In poultry, people use the 1% injectable orally, topically and they also inject it. There is also a 5% pour-on that people use topically in poultry.

So glad this old thread popped up. Done lots of reading and research since I posted this and learned quite a bit. Yes, people do use it, but there is a study that shows ivermectin as an ineffective wormer in poultry (see below) as well as several posts from people that lost birds to worm infestations even though they were using it. Ivermectin will not treat feather lice! Yes, people do use it topically, but 1% should be injected or given orally, not that it will do anything, but it should not be used topically.

Read this:

• https://www.backyardchickens.com/t/867541/important-information-on-ivermec-warning-autopsy-photos

Now to address my misinformation... Liquid ivermectin comes in 1% (10mg/ml) injectable and pour-on which is *actually* .05% (5mg/ml), *not* 5%, that's a gross error on my part. So sorry!

If after reading this you still want to use it, the doses are:

• For Pour-on - .5mg/kg, that's .1ml/kg or .1ml per 2.2 pounds
• For 1% injectable (can be given orally) - .2mg/kg, that's .02ml/kg or .02ml per 2.2 pounds

Ivermectin has a wide margin of safety, so you can use a little more, just be smart about it. IMNSHO, a better wormer would be Valbazen or Safeguard.

Ascaridia = roundworm
Heterakis = Cecal worm
Capillaria = Capillary worm

Ivermectin as a bird anthelmintic--trials with naturally infected domestic fowl.

Oksanen A, Nikander S.
Abstract

To evaluate the use of ivermectin as a bird anthelmintic, 29 White Leghorn hens naturally infected with Ascaridia spp., Heterakis spp. and Capillaria spp. were treated with 0.2, 2 or 6 mg/kg intramuscularly or 0.2 or 0.8 mg/kg orally. Faecal samples were collected before treatment and at autopsy, 2, 6, or 16 days after treatment, when the intestines were also examined for helminths. None of the treatments gave satisfactory anthelmintic results.

I used the 1% injection type to treat my budgies and parrots. Put it in their drinking water. I wish I could remember the dosage but it worked like magic. I treated them again in 2 wks and have never had any mite problems since (10 yrs or more). One of the chicken info sites I've checked out is that of www.shilala.homestead.com. They list the use of Ivermectin - they use a product called Eprinex and dose their flock in the drinking water. They remove the water source in the morning making sure there are no standing water puddles or any where the birds could get water. Then around noon, using a quart bowl, pour about 1 qt of water in the bowl and add 1/4" of the Eprinex. It floats on top of the water. When all have drank from the bowl, it is put into the fridge and regular waters are returned. Then in the evening, the regular waterers are again removed and the water bowl with Eprinex is given. Finally, the regular water is put back again for morning. It is recommended to dose again in 10 days. For individual dosing, 1 cc= 1 ml and they recommend .5cc per 11 lb bird - Large Fowl and .25 cc per 5.5 lb bird - Bantam. About the Canker problem and your rooster you can read about Canker and Protozoan infections here: http://www.friskyfinches.com/bird-care-library/canker-and-protozoan-infection. Their advice is excellent and although it is geared for finches, I have found it useful for my chickens as well as my parrots. There are some very good avian/pet products mfg'd in Australia under the name of VETAFARM. Although there is no cure for canker, it can be controlled. They recommend a product called Ronivet-S 12% along with a broad spectrum antibiotic. One of the best things is you can ask them questions and they take the time to answer. I just found their info very useful. Hope you do too. Good luck.

Thanks for this. There is so so much conflicting info out there.
I am wondering what you use for feather lice?

I use a permethrin based poultry dust.

You are thinking of ivermectin pour on, not the injectable. The injectable works against mites well, but wont kill worms in chickens. The ivermectin pour on is placed on bare skin on the back of the neck and quickly absorbed into the bloodstream, about 1/2cc for standard size birds. The ivermectin pour on will kill most worms, but not all, and it will kill mites as well. Normally there's a 14 day withdrawal period. You dont want to feed the eggs back to the chickens. There's residue in the eggs that can extend the withdrawal period, not to mention future wormer resistance to the product. This is why the injectable doesnt work in chickens, overusage as a miteacide instead of its primary purpose as a wormer as evidenced in this link:

I clicked on that link and there is no information and most of it is in another language

So I bought Eprinex (eprinomectin). On the bottle it says for cows there is zero slaughter withdrawal and zero milk discard. That it kills lungworms cattle grubs(all stages) Lice 5 kinds, mange mites 2 kinds horn flies chorioptic mange mites were gone completely in tests 8 weeks after treatment. It says it can be used on lactating cows. It also says only can be used topically not injected or oral. I know if a chicken has worms the eggs are not affected and can still be eaten. So Im not sure of the withdrawal of eggs.
