Ivermectin dosage

[fonkymc]

Hi All

I see now and then that some people use Ivermectin on their hens. If so, what is the dosage and what strength? I am reading conflicting information when I research.

The recommended dose is 5mg/kg per Poultry DVM, which is a good source for reliable information: http://www.poultrydvm.com/drugs/ivermectin.

Where I live, ivermectin is sold as a liquid, so you will need to look at the concentration (mg/mL) and convert that. If you post the product you plan on using I would be happy to help with unit conversion.

Just in case anyone is reading this.. I do not think that is the correct recommended dose.. They are saying 5mg or more is a lethal dose.. see below from the website
-------

Note. Dosages over 5 mg/kg of body weight of the bird are toxic to pet poultry. Ivermectin is not effective on tapeworms.

For chickens and ducks: 0.2-0.4 mg/kg PO, SC, IM, topical once, and can be repeated in 10-14 days.

The max dose for Pour On Ivermectin is 1 mg/kg which is 0.09 ml per pound. This is given topically only.
A five pound hen would get 0.45 ml.

The minimum effective dose for Pour On Ivermectin is 0.5 mg/kg, which is 0.045 ml per pound. This is given topically only.
A five pound hen would get 0.23 ml

You are confusing yourself by doing a lot of further research. Again, may I suggest that if you are not confident in dosing info, that you take the Pour On back. Treat your birds and housing intensely with Powder/Spray in 7 day intervals.

Max Dose Pour On is 1mg/kg which is 0.09mg per pound of weight.

The math is:
1 ÷ 2.2 x 1 ÷ 5 = 0.09 this is the dose per pound of weight for Pour On.

How do you weigh that out in mg? This is a liquid and should be weighed out in ml. They don’t convert and it’s confusing to say mg/kg.

You weigh the chicken to figure your dose.

For every pound of chicken, you would draw up 0.09ml of Pour On into your syringe.

Most medication is dosed as mg/kg even for humans

Max Dose Pour On is 1mg/kg which is 0.09mg per pound of weight.

The math is:
1 ÷ 2.2 x 1 ÷ 5 = 0.09 this is the dose per pound of weight for Pour On.

For 5mg Ivermectin the dosage would be:
- about 4 drops per chicken (but it depends on chicken weight).
- about 1-2 drops per quail.
HOW TO CALCULATE DOSAGE IN DROPS to be accurate:
The instruction on 5 mg Ivermectin suggests to use 1 ml Ivermectin per 22 lb of body weight.
First, you would need only a few drops per bird - use a pipette, not a syringe.
Take your pipette. Count how many drops in 1 ml.
Fill it with water to 1 ml mark and start squeezing drops out, count them to know how many drops are in your particular pipette in 1 ml of liquid.
In my pipette 1 ml was roughly 25 drops of liquid (yours can be less or more, so, don't use my number).
So, 1 ml = 25 drops Ivermectin = per 22 lb body weight.
Weigh your bird.
My quail weigh about 1 lb each.
Calculate how many drops of Ivermectin per bird.
Per 1 lb quail: 25 drops Ivermectin : 22 = 1.14 drops.
So, slightly above 1 drop per quail. I had to use 2 drops because if you under-dose, the parasites might develop resistance, which is not good.
Plus, I have seen others use 2 drops per quail and the birds were fine. 2 drops is also under the lethal warning level and is not overdosing.

NATURAL MITE TREATMENT SPRAY RECIPE
The author is Amy Fewell. She prefers this natural treatment over Ivermectin as it has been more effective for her flock. Also, there is NO WITHDRAWALL period like with Ivermectin (can't eat eggs for 7 days). The only downside of the natural spray is that you have to stay on it every day for a couple of weeks, and then just do preventative treatments twice per week.

HOW TO CALCULATE DOSAGE IN DROPS to be accurate:

That dose is equal to 0.5 mg/kg.

Take your pipette. Count how many drops in 1 ml.
Fill it with water to 1 ml mark and start squeezing drops out, count them to know how many drops are in your particular pipette in 1 ml of liquid.

No need to do that.

Per 1 lb quail: 25 drops Ivermectin : 22 = 1.14 drops.

The math using the labeled dose is:
1 pound / 2.2 (converts to kg) x 0.5 (labeled dose) / 5 (number of milligrams per one ml) = 0.045 ml which

0.045 ml is about 2 drops from a 1 ml syringe.

No need to do that.

The math using the labeled dose is:
1 pound / 2.2 (converts to kg) x 0.5 (labeled dose) / 5 (number of milligrams per one ml) = 0.045 ml which

0.045 ml is about 2 drops from a 1 ml syringe.

There is no 0.045 ml mark on my syringe, and all syringes are different with different size drops... So, I go by the actual syringe (actually a pipette) I am using based on its drops per ml. The older one I used gave me 18 drops per ml, so, go figure.
