Levamisole wormer info needed

[sweetfieldsfarm]

My head is spinning, LOL. Many powders weigh approximately 5 grams per teaspoonful, but it can vary with the powder. Some may be lighter or heavier. You are pretty close using 1/4 tsp for a gram with this powder, since there are 4 grams per tsp.

@casportpony is very good with dosages, and when she posts one, it is usally from a vet drug book or through tedious measuring and checking, so I would follow her instructions. She has found errors in dosage directions of manufacturers drug labels quite a few times.

I would give the wormer orally, because chickens may not drink the recommended amount of water, and the water may taste bad to them. It is time consuming, but individual dosing can be the most effective method with little error for underdosing or overdosing.

Lastly, I hope that you know that levamisole is not the safest or commonly used product for worming chickens. Very few people use it in the US anymore, although in many foreign countries, that may be the only one available. I recommend Valbazen or SafeGuard. Those have to be dosed to each chicken as well, but are extremely safe and will treat most chicken worms. Let us know if you need dosages.

LOL! Right? Mine is too!

You are so kind to help me with all of this though! If all else fails, I can always buy something new if this is not all that safe to use too.

. Missed that too.

Okay...let me go look at the numbers again.

Thank you also casportpony! I trust you both and the community here more than most!

I think it was just getting to a point where my head was hurting with all of the different numbers trying to figure this out last night. The friend of a friend raises silkies and sweared by it, but of course I've had no luck reaching her on dosage amounts either... lol

Okay that powder is 46.8 g of levamisole hydrochloride in 52 grams
46.8/52 = 0.9 grams of levamisole hydrochloride per gram of powder (90%)

If one teaspoon of powder weighs 4.8 grams, 4.8 x 0.9 = 4.32 grams of levamisole hydrochloride per teaspoon.

One of my references says 0.8 grams per liter, so 0.8 x 3.785 = 3.028 grams per gallon.

3.028/4.32 = 0.7 teaspoons per gallon
0.7 x 5 = 3.5 teaspoons per five gallons.

Your math was very close to what I came up with!

Thank you both @casportpony and @Eggcessive! You have been so helpful with figuring this all out! I honestly just had too much of a headache last night from the various numbers to attempt anything just yet lol

I'm so happy to be here in good company though! I'm also excited to participate in other forums when time allows

If you can weigh 1.1 grams that will give you 1000 mg of levamisole. You could try mixing the 1.1 grams with 20 ml of water and that will give you 20 ml @ 50 mg/ml.

What's the link to that pdf you found?

Anyway, if you decide to go with the max that the PDF you found:
5 pound bird x 16 / 50 = 1.6 ml per five pounds

I am reading that 40mg/kg is the toxic level for chickens. Should this 1.1 grams be mixed with a higher amount of water instead like 30cc? I’m confused by all this but don’t want to overdose when I treat in bolus form.

Where are you reading that? Because the veterinary reference I have says that 40 mg/mg is the chicken dose.

Scratch that!! It was on parasitipedia but that is for birds. It says poultry is much better tolerated. I’ll stick with this dosage you gave. Thanks!!

Keep in mind that all I did was look up the dose in a book and do the math, I have not used this medication. So please do double check everything before you use it.
