Abstract
The Food and Drug Administration (FDA) is amending the animal drug regulations to more accurately reflect the recent approval of two supplemental new animal drug applications (NADAs) filed by Pharmacia & Upjohn Co., a Division of Pfizer, Inc. The supplemental NADAs provided for increased levels of monensin in two-way Type C medicated feeds containing melengestrol acetate and monensin, and in three-way Type C medicated feeds containing melengestrol acetate, monensin, and tylosin phosphate for heifers fed in confinement for slaughter. These amendments are being made to improve the accuracy of the regulations.
