## 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 nicarbazin and bambermycins Type A medicated articles to make Type C medicated broiler chicken feeds to be used as an aid in preventing outbreaks of cecal and intestinal forms of coccidiosis, and for increased rate of weight gain and improved feed efficiency.
