This is very interesting. I use the Purina Start & Grow, and the Purina Flock Raiser. I thought the Start & Grow was medicated, but I just checked the tag and the unopened bag I have doesn't list the amprolium like it used to. The Flock Raiser does have it on the tag still, but no where on the bag itself does it say "Medicated".
To answer the original question, the medication is Amprolium .0125%, which it a coccidiostat. It is used to prevent and build resistance to coccidiosis.
