What is the reason for medicated salt licks?

Safe-Guard makes dewormer salt licks to combat various parasites that infect cattle. Bovatec makes salt licks with lasalocid sodium for the purpose of helping increase the rate of gain for pasture stocker/slaughter/feeder/replacement cattle. These two brands are the only known "medicated" salt blocks that is made for livestock; all other salt blocks are not medicated and are primarily of trace mineral, iodine, cobalt and iodine or iron, cobalt and iodine. None of these other blocks are termed "medicated."

Also, there is no known company that makes salt blocks with ephedrine or any other drug other than the dewormer medicine made by Safe-Guard and increase ADG by Bovatec.
