New Animal Drugs for Use in Animal Feeds; Melengestrol; Monensin

摘要

The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Pharmacia & Upjohn Co., a Division of Pfizer, Inc. The supplemental NADA provides for use of the same increased dose levels approved for single-ingredient Type C medicated feeds for heifers fed in confinement for slaughter containing melengestrol acetate or monensin in two-way, combination drug Type C medicated feeds containing melengestrol acetate and monensin.
