Nope, they are wrong, trust me. The 800 mg dose is 1.5 tablespoons, not 1 tablespoon. Just because a mfg says it should be something doesn't mean it's correct.

 

Look at their other errors. Since when does 1/2 tablespoon = 1 ounce?

 Mixing Instructions: 6.4 OZ WILL MAKE:

100 gal containing 100 mg of tetracycline hydrochloride/gal

50 gal containing 200 mg of tetracycline hydrochloride/gal

25 gal containing 400 mg of tetracycline hydrochloride/gal

12.5 gal containing 800 mg of tetracycline hydrochloride/gal

From: http://www.drugs.com/vet/duramycin-10.html

The math is easy... 

Each package has 10 grams (10,000 mg)

10,000 mg / 800 mg  = 12.5 gallons medicated at 800 mg - This matches what http://www.drugs.com/vet/duramycin-10.html says.

 

Buy a package of it and see for yourself. Measure out the number of tablespoons. If there are 12.5 tablespoons, then the mfg is correct, but I think you will find that there are 18-20 tablespoons, which means the 800 mg dose is no less than 1.5 tablespoons.

 

Even better, weigh a tablespoon. How much you wanna bet that one tablespoon will weigh ~10 grams? 

Package weight = 181 grams

181 / 10 = 18 tablespoons

 

Don't feel bad, I used to post the same misinformation. :hugs 

 

One tablespoon of most powders used in poultry is gonna weigh 9-10 grams. 

 

If you still don't believe me, find someone you know that's knows a little about math and ask them.

@FarmerJohn5626 , this one is also incorrect:

 

~5 teaspoons = 800 mg

2.5 tablespoons  = ~1200 mg.

To Joe Bryant.....that measurement that the pharmacist gave you is assuming that the chickens drink all 2 gallons of the mixture, which they wont....I think we all need to talk to a vet.

I bought the fish antibiotic API TC tetracycline. 500mg/packet
Tetracycline grams/teaspoon rather. That would be helpful.

Also, is the 800mg/gal dosage safe for juvenile pullets and bantams? I only have 1 full size hen right now, 3 pullets whom were born oct 1,16 and a bantam rooster.e

The quart dose would be 200 mg, yes?
If one pack has 500 mg tetracyline, then I think the amount to use is 0.4 packs per quart?
