Glenda, I think this may have been a PM from me but I must have messed up. Read where you offered somebody dosing help re: de-worming. Math is not my strong suite and I couldn't remember the dosing on Ivermectin even though I have used it before......AND had a window of time that I would actually have help and needed to get my 42 girls and 2 roos medicated. I went with .4 cc. I will be repeating in 10 days so any help you can give me will be appreciated! :)

dosge of Ivermectin to worm chicken

http://fowlfacts.proboards40.com/index.cgi?board=medshhh&action=display&thread=270
this url is BYC
and heres what it says:

pips&peeps said this :

1.5 cc per gal of water dosage for chickens only.

waterfowl consume too much water and can od.

It will not kill the usuall dander type lice as they do not eat blood meals.

SUNDOWNWATERFOWL said this:

I had to use it on my ducks. I gave each 0.05 cc (i think) right in their mouth.

Ive read when treating chickens, Take a 1 inch strip and put it in hot water and let it sit overnight. Then pour the womer water into a 1 gallon waterer and fill up. Then give them that for 3 days. I did that on my new OEGB I purchased, just as a precaution.I used paste! use the 1.87%

BIRCH RUN FARM said I've never had effective results with Ivermectin in water. It is an oil base and does not mix well at all. I use an eye dropper and apply it to the chicken's skin below their vent. I have a head lamp that has a red light and I just do them at night when they are on the roost.

I let the dog have the eggs for the ten days following. No issues. But most of them are not laying when I treat them.

SKEYSROCKET OSTE
I just finished putting it on my showgirls necks. Since the backs of their necks are bare it was pretty easy to do. I waited until they were roosting for the night and went down the line.
I have a question as well. I read this on an MSN forum, but can't post there with my question.

"Ivermectin is effective against a large variety of worms and works also against mites. You can place a drop of the oil based medication on the skin behind the neck, or administer orally: Give 7 drops orally to a bantam and 0.25cc to a large chicken.

If you put it in their waterer, use 6 cc / gallon for 2 days and to treat for worms, repeat in 12 days. To inject, give subcutaneously as follows: Little bantams (rosecombs, golden seabrights: 0.5cc. Brahmas, Silkies, Orpingtons: 1.0 cc. Standards: 1.5 cc. Jersey Giants: 2cc"

My question is do I have to repeat the drop on the back of the neck? It isn't clear here if I do or not?
I type using a bigger font size because my new glasses suck and I can't read anything small with them.
I've never lost a bird from this treatment.

Glenda Hewood
maybe some where in this you will find your answer.
 
There are four types of ivermectin, and the dose for each one is different

  • 1% = 10 mg/ml (injectable for cattle)
  • 0.5% = 5 mg/ml - Pour on for cattle
  • 0.08% = 0.8 mg/ml - Sheep drench (oral)
  • 1.87% = 18.7 mg/ml - Horse paste


1% (10 mg/ml) injectable can be given orally, by injection, and I have read about people using it topically. Maybe I will try that next.

The pour on is 0.5% (5 mg/ml), not 5% (50 mg/ml). It is meant to be used topically, not orally, and never by injection.

1.87% horse paste can be given orally, and I think I read about someone using it topically. Maybe I should add that to my list of experiments.

Ivermectin Sheep Drench is 0.08% (0.8 mg/ml) is given orally.

I will look up doses for all four.

AND SO YOU CAN FIND IT DOWN TOWARDS THE BOTTOM

Glenda Heywood
then in 10 days worm with Ivermectin
this wormer goes into the BLOOD STREAM and kills the worm larvea as was needed

then people feed DE in the feed 2% of feed given is DE then the DE knicks the worms soft skin and
they the adult worms die of dehydration and then dry up and provide protein to the chickens body

thus twice a yr do the chemical wormer to get the worm larvea in the blood stream and DE the rest of the time

with that said there are three kinds of wworms that need vet wormer Droncit and one other to kill
tape worms, gape worms and one other kind of worm such as cecel worm

but the two I mentioned to give is the most popular kinds

the Ivermectin is expensive but can be used on other animals/ also stays stable for along time

Yes Merek had provided Ivermectin in the 3rd world countires for eye worm blindness of people living around rivers
called river blindness
Before that the peoples families had to take care of them for life of blindness
now Marek's gives them two pills a yr
you can email me for any other info PM me as I will try and help you all with worming
Glenda L Heywood Cassville Missouri

CHICKLERANCH POTED
We use Ivermectin on our flock, administered orally. Vet recommends a second worming 7-10 days later with fenbendazole (a popular wormer for horses). We eat our eggs after worming, no ill effects.

We use DE on the perches in the coop, in the pen and wherever the chicks dust.

NOTTHEMOMMA POSTED
http://us.merial.com/producers/dairy/products/dairy_ivomec_pouron.asp

The Ivomec website shows it's 100% effective on lice.

That's what I would treat with. Though I can understand you wanting to avoid treating with medications. If the infestation is high though, you may end up losing some of your chickens.

One of those between a rock and a hard place decisions.

Glenda Heywood
I finally found this information on amount?????
AND MY INFORMATION ON WORMING BY NATHALIE ROSS FROM TEXAS!!!

DAWG53 POSTED
I dont recommend ivermectin since it's ineffective in chickens as a wormer. Here's a link, scroll down to "Summary."
http://onlinelibrary.wiley.com/doi/10.1111/j.1439-0450.1989.tb00635.x/abstract
I recommend safeguard or valbazen for worming.

Summary

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.

CASPORTPONY POSTED
And Fenbendazole 10% (Safegaurd or Panacur, liquid or paste) for internal parasites. I've even used them at the same time, but I would not recommend doing that based on the depression the birds showed for 24 hours after.
-Kathy

CHOONIECAT POSTED about pour on ivermection on BYC
OK-tons of conflicting info and I THINK I have the little bit I could understand correct.

POUR ON 1/2cc per bird(standard chickens)on skin.

Somewhere on here it was said "6 drops per bird" BUT what kind of dropper????

Could cause HUGE dosage difference if different "droppers" are used. So I am going with the 1/2 cc suggestion(between shoulder blades) Is this possibly a problem? I hate to go to the effort(32 birds tonight) if it will have NO effect and I also don't want them to die!TY.

COWCREKGEEK posted
Ivermectin (1% injectable for cattle)
Since Ivermectin went off-patent, there are several manufacturers producing it.
Ivermectin has been used orally via extra-label scripts to treat Northern Fowl Mite
and capillaria infestations. Only mites that are on the birds are killed.

The 1% injectable cattle formulation has been used as follows
(personal communication):
• 1 ml of 1% Ivermectin injectible + 1 ml. propylene glycol + 2 gal H2O, proportion at 1 oz./gal D.W.
• Administer 2 times, 10-14 days apart. There is a 30 day withdrawal (destroy commercial eggs for 30 days post-therapy.)


TAPROCK POSTED

This is what I do per our poultry vet - doesn't always mean it's right.

I use ivomec pour on for cattle (5 mg/ml). I put 3 drops on bantams, 4 regular, 5 really big or fluffy and 6 on my guineas.

I use it for Fowl mites. You don't have to withhold eggs.

I was told every three weeks but then it was changed to sooner if needed.

Also I use a plain old eye dropper. I have had no adverse effect overdosing,

as I can say a couple wilder acting birds got much more than directed.
I have 63 chickens and 5 guineas so it takes a while.
I usually do it after dark with a headlamp and just climb around the coop.

Glenda Heywood finally more information on ivermectin dosage,
my friend Nathalie Ross who was a vet tech,her information on ivermectin dosage!!!
And my friend RANDY HENRY who studied at vet school, his dosage on Ivermecton!!!



COWCREEKGEEK posted
The injectible in water is the only treatment that vets can get away w/ doin' under current FDA rules, and the pour-on goes beyond off-label use, despite folks doin' it for quite some number of years. I do know of resistances developing w/in flocks, when it's used to often, or under-dosed just a few times. I've never read of overdosing, not that I've any studies to offer ... I wouldn't eat the eggs for at least ten days.

The dropper used is the common drugstore variety of medicine droppers, by all but Nathalie Ross, who uses a 20 Guage needle as her dropper.

Also, do NOT use the Ivermectin Plus, as it contains an additional wormer that is not safe for chickens.

When your estimation is short, I'd dose the extra drop, as overdosing does not appear to be an issue w/in such narrow margins (i.e. the difference between the 7 or 9 drops is less than +/-12%.

And, finally? I'm not a vet, and do not encourage you to violate FDA rules/regulations, and I have not personally verified these infromations, which I provide as a second-hand collection of other folks' suggestions.

For specifically the IVOMEC Pour-On for Cattle, from Drugs.com:

The dose rate is 1 mL for each 22 lb of body weight. The formulation should be applied along the topline in a narrow strip extending from the withers to the tailhead.

--- 01 --- Randy Henry

Directions for .5% ivomec with oil base put on shoulder
only not internally.
(1 1 drop small bantam such as female OE
(2 2 drops large bantam male like OE
(3 3 drops most bantams
(4 4 drops larger bantams and smaller commercial hens
(5 5 drops commercial large fowl and smaller large
fowl
(5 5 drops Large fowl chicken
(7 7 drops larger males of large fowl breeds of
Chickens.

--- 02 --- Nathalie Ross

For the pour on (.5% oil) Ivermectin (not Eprinex) the dosage I
use is as follows:
1 drop - OEGB sized small bantam female
2 drops - OEGB sized small bantam male
3 drops - average bantams
4 drops - large bantams, small commercial fowl
5 drops - most commercial fowl, small giant hens
6 drops - giant breeds of chicken

I always use a 3 cc syringe that I just fill to about 2 cc's with a 20 gauge needle. The needle WON'T be injected into the chicken, but does make it easier to dispense a controlled correct sized drop. It also is easier to get in there between the feathers.

NOTE: Confirmed this info in a second incident or author, in a different post.

TazneenDragon, via Rating system of Amazon
specific product: Vurvet Ivermectin Pour On 250 Ml

It's pretty much the same for chickens, which is how I discovered this product. Nothing else could get rid of the scaly feet mites because they didn't have them bad enough to raise the scales substantially, so that topicals had a problem getting in the small crevices. Between the topicals and the Ivermectin, everyone is making a great recovery. For small bantam hens, 3 drops. 4 drops for bantam roosters. I give around 9 drops to my 7 pound rooster. Make sure to give it every two weeks, though, because it is only effective on parasites that take blood meals. That means that anything in egg form will not be effected, so you will have to get them as they hatch out by keeping on top of the two week schedule.

CASPORTPONY POSTED THIS:

Five pounds is pretty close, but might be better to make a list of all your breeds, then look up the weight each one and make a note. Some breeds, like Rhode Island Reds, as Orpingtons, might weigh more.

The drop thing drives me nuts, so I always do the math.
big_smile.png

10 ml per 220 pounds works out to 0.5 mg per kg. The math is pretty easy if you use this formula.

Weight of bird in pounds, divide by 2.2 (converts to kg), times 0.5 (mg per kg needed for this drug), divide by 5 (number of mg per ml) = number of ml needed.

1 pound
1 / 2.2 x 0.5 / 5 = 0.045 ml per pound.

5 pounds
5 / 2.2 x 0.5 / 5 = 0.227 ml

10 pounds
10 / 2.2 x 0.5 / 5 = 0.45 ml

And one can verify the above by checking the dose for the 220 pound animal.
220 / 2.2 x 0.5 / 5 = 10 ml

So, now about worming... Ivermectin is not a good poultry wormer. It will probably treat large roundworms, and it might treat cecal worms, but there are some studies that say it will not treat capillary worms or gapeworms. FWIW, peafowl breeders use ivermectin for lice and mites, but we don't use it for worms.

Have you have had a fecal done to check for worms?
