I'm still looking at the numbers, but I think this powder is a much less concentrated version of what we have here in the US.I am not an expert on oxytetracycline, but in chickens the dosage in the water is supposed to be 400 to 800 mg of drug to each gallon of water for 7 days. 1000mg equals 1 gram, so that seems like too much. Since the oxytet is for smaller birds, I think it may be too concentrated. I will wait for @casportpony to respond to this.
