Revised Labeling For Some Medicated Feed Products

January 30, 1997

The approved conditions of use for Type A medicated articles containing chlortetracycline and oxytetracycline have changed as a result of the approval of several supplemental new animal drug applications (NADAs) in accordance with findings of the National Academy of Sciences/National Research Council (NAS/NRC), Drug Efficacy Study Group's (DESI) effectiveness evaluations and the approval of "me-too" NADAs that were dependent upon the DESI-finalization. Products affected by this change include:
