## 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. The supplemental NADA revises the concentration of monensin in Type C medicated feeds used for improved feed efficiency, and for the prevention and control of coccidiosis in cattle fed in confinement for slaughter.
