## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to remove dairy replacement heifers from the pasture cattle class for which free-choice, loose-mineral medicated feeds containing bambermycins are approved. This action is being taken because a level of selenium for inclusion in such feeds has not been established for dairy cattle under the food additive regulation for selenium.
