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 Alpharma Inc. The NADA provides for using currently approved, single ingredient, Type A medicated articles in making combination drug, Types B and C medicated, swine feeds containing bacitracin methylene disalicylate and chlortetracycline. The Type C medicated feed is used for increased rate of weight gain and improved feed efficiency due to the activity of bacitracin, and treatment of enteritis and pneumonia caused by certain bacteria susceptible to chlortetracycline.
