## 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 & Co. The NADA provides for combining approved narasin/nicarbazin (1:1 fixed ratio) and bacitracin methylene disalicylate (BMD) Type A medicated articles to make combination drug Type C medicated broiler chicken feeds for prevention of certain forms of coccidiosis and for increased rate of weight gain and improved feed efficiency.
