## Abstract

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a new animal drug application (NADA) filed by Elanco Animal Health, A Division of Eli Lilly and Co. The NADA provides for use of a ractopamine hydrochloride Type A medicated article to make Type B and Type C medicated swine feeds. The Type C medicated finishing swine feeds are used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness. The regulations are also amended to provide for an acceptable daily intake (ADI) for ractopamine and tolerances for drug residues in edible products derived from treated swine.
