Yeah so the amprolium blocks the uptake of thiamine B1 by the coccidia, that’s how it works. But obviously the bird doesn’t get the vitamin either which is why you can give the supplement afterwards.
I’m not sure if the best course of action would be to completely retreat at the higher dose without the vitamin supplement, or do the maintenance/lower dose sans vitamins… There are some experienced people on here who help me a lot and maybe they have a clearer answer?
