    SUPPLEMENTARY INFORMATION: Fort Dodge Animal Health, Division of 
    American Home Products Corp., 800 Fifth St., NW., P.O. Box 518, Fort 
    Dodge, IA 50501, filed supplemental NADA 9-576 that provides for use of 
    Synovex S (200 milligrams (mg) progesterone and 20 mg 
    estradiol benzoate) implanted in the ear of steers fed in confinement 
    for slaughter at approximately day 70 following initial implant of 
    Synovex C (100 mg progesterone and 10 mg estradiol benzoate) 
    when used as part of a reimplant program for increased rate of weight 
    gain. The supplemental NADA is approved as of July 14, 1998, and the 
    regulations in 21 CFR 522.1940 are amended by adding paragraph (d)(3) 
    to reflect the approval. The basis for approval is discussed in the

    is of a type that does not individually or cumulatively have a
