Lol, sure. Note that all injectable are still OTC, so if someone wanted to use sulfadimethoxine to treat coccidiosis, I think they can use the injectable orally. Tetracyclines, just buy doxycycline for birds or fish.
Kathy, where do you find sulfadimethoxine in oral? I have not seen that at my feed store, but I may not be looking in the right place....is it cattle? goat?
Honestly I'm still using an old bottle that will go out of pull date soon....while it can be toxic, when you are dealing with a weird situation and don't know if it's bacterial or coccidia lurking, that has been a great go to that generally snaps birds out of most things quickly.
