New Animal Drugs for Use in Animal Feeds; Lasalocid

Riepilogo

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of two supplemental new animal drug applications (NADA's) filed by Hoffmann-La Roche, Inc. One supplemental NADA provides for the addition of certain lasalocid- containing Type A medicated articles to dry, powdered milk replacer before reconstitution. The reconstituted Type C medicated feed is used to control coccidiosis in nonveal calves. Additionally, FDA is amending the regulations to reflect approval of another supplemental NADA which modifies the lasalocid feeding directions for control of coccidiosis in cattle.
