## 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 Hoechst Roussel Vet. The NADA provides for combining approved single ingredient lasalocid and bambermycins Type A medicated articles to make Type C medicated broiler feeds to be used for prevention of certain forms of coccidiosis and for increased rate of weight gain and improved feed efficiency.
