## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by ADM Alliance Nutrition, Inc. The supplemental NADA provides for the use of a lasalocid Type A medicated article containing 20-percent lasalocid activity per pound to make free-choice Type C medicated feeds used for increased rate of weight gain in pasture cattle (slaughter, stocker, feeder cattle, and dairy and beef replacement heifers).
