How much of the powder should she mix with their water? and for how long?
She has Gallon size waterers and her problem was she couldn't find a tsp/tbsp, "everyday" measurement for the medicine.
I poured the 181 gram bag of Duramycin-10 into a measuring cup and it measured right around 1 cup.
It says that the 181 grams of powder contains 10 grams of tetracycline, so that means that there's 10 grams of tetracycline in a cup of Duramycin-10.
1 cup is 16 tablespoons, which is 48 teaspoons. So I divided 48 into 10 grams to get the number of grams of tetracycline per teaspoon of powder, which is 0.204 grams of tetracycline/teaspoon of powder.
1 tsp of Duramycin-10 equals 0.204 grams = 204 mg, which means that I want to add 2 teaspoons per gallon
I want to dose my hens at 400mg tetracycline per gallon of water, but I only have 3 hens so I want to mix it by the pint not the gallon.
A pint is 1/8 of a gallon, so I want 1/8 of 2 teaspoons Duramycin-10, which is 1/4 of a teaspoon/pint.
