New Animal Drugs for Use in Animal Feeds; Bacitracin Methylene Disalicylate and Fenbendazole

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 use of approved bacitracin methylene disalicylate and fenbendazole Type A medicated articles to make combination Type B and C medicated feeds for growing and finishing swine and pregnant sows for the removal of various internal parasites, for increased rate of weight gain and improved feed efficiency, for control of swine dysentery associated with Treponema hyodysenteriae, and for control of clostridial enteritis in suckling pigs caused by Clostridium perfringens. Technical corrections are also being made.
