Hi, pretty long quotes, so I'll try to get it fast...
Dosing information for Tylan 200:
Tylan 200 dosing:
It has been found that an injection of Tylan 200 – 0.5 ml in the breast muscle, and a follow up injection 48 hrs later gives excellent results
Some people give the dosages below, it will be up to you to make the call as to how much you give you bird, as to how severe the problem is
For a bantam hen give between 0.1-0.2.ml .
For a larger fowl give between 0.2-0.3 just depends on its weight
Dosing by weight of bird: (Turkeys and chickens)
Between 30-35 mg/kg, two to three times per day depending on severity.
The Tylan injectable can be given orally but it isn’t as effective as when you give it by injection.
How to do the math
First you should have an idea of how many pounds your chicken weights. There are 2.2 pounds in 1 Kg. So take the weight in pounds and divide by 2.2. This will give you the Kg of your bird.
If you have, say, a 1.3 kg bird and you want to know how much tylan to give it at a dose of 35 mg/kg. You know that you need to multiply 35 mg x 1.3 as this is the weight (in kg) of the bird. This tells you that your bird needs (35mg/kg x 1.3kg = 45.5 mg). Now you know how many mg you bird needs, but how much tylan is that? Well, if there’s 200 mg/ml in tylan 200, then (you can use cross-multiplication too for this) divide 200 mg/ml into 45.5 mg to tell you how many ml you need. 45.5 mg / 200 mg/ml = .2275 ml which is 0.23 cc or 23 units. On a 1 cc syringe, it is very easy to measure out 0.23cc or 23 units of tylan.
I didn't really follow any set rules as to how long to treat them. I just treated until they got better (very scientific)
I had to look this up since it's been a couple of years since I had to treat for this horrible disease, and I haven't had any more Coryza!!
The one banty I treated is chasing around 2 roosters that she raised this year. Ya gotta love um!. Good luck!
