## 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 Elanco Animal Health, Division of Eli Lilly & Co. The supplemental NADA provides for use of monensin Type A medicated articles to make Type B and C medicated cattle feeds to be fed at 0.14 to 0.42 milligram per pound (mg/lb) of body weight per day, to revise feeding directions, to provide added uses for monensin Type C medicated feeds for prevention and control of coccidiosis, and to amend the residue tolerances for monensin residues.
