## 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 combining approved monensin and virginiamycin Type A medicated articles to make combination drug Type C medicated growing turkey feeds used for prevention of certain forms of coccidiosis and for increased rate of weight gain and improved feed efficiency.
