DEPARTMENT OF HEALTH AND HUMAN SERVICES
21 CFR Part 558


Animal Drugs, Feeds, and Related Products; Melengestrol Acetate 
and Tylosin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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 The Upjohn Co. The supplemental NADA 
provides for use of single ingredient Type A medicated articles 
containing melengestrol acetate (MGA) and tylosin to manufacture 
certain combination drug Type B and Type C medicated feeds for heifers 
fed in confinement for slaughter. The supplement provides for use of a 
dry MGA Type A article to make a dry Type B or Type C medicated feed.

EFFECTIVE DATE: March 1, 1995.

FOR FURTHER INFORMATION CONTACT: Jack Caldwell, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-594-1638.

SUPPLEMENTARY INFORMATION: The Upjohn Co., Kalamazoo, MI 49001, filed 
supplemental NADA 138-995, MGA with Tylan (MGA with tylosin), which 
provides for use of approved MGA and tylosin Type A medicated articles 
to make Type B and Type C medicated feeds for heifers being fed in 
confinement for slaughter. The supplement removes the requirement for 
making dry pelleted Type B or C medicated feed. Therefore, dry MGA and 
tylosin Type A articles may be used to make a dry Type B or C medicated 
feed containing MGA and tylosin.
    This supplement is approved as of January 13, 1995. Accordingly, 21 
CFR 558.342(c)(4)(ii)(C) is amended by removing the existing reference 
to a pelleted medicated feed to reflect this approval.
    This is a manufacturing supplement to an approved NADA. Approval of 
this supplement does not require added safety or efficacy data or 
information. Therefore, a freedom of information summary as provided in 
part 20 (21 CFR part 20) and Sec. 514.11(e)(2)(ii) (21 CFR 
514.11(e)(2)(ii)) is not required.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this supplement for food-
producing animals does not qualify for marketing exclusivity because 
the supplement does not contain new clinical or field investigations 
(other than bioequivalence or residue studies) and new human food 
safety studies (other than bioequivalence or residue studies) essential 
to the approval and conducted or sponsored by the applicant.
    The agency has determined under 21 CFR 25.24(d)(1)(iii) that this 
action is of a type that does not individually or cumulatively have a 
significant effect on the human environment. Therefore, neither an 
environmental assessment nor an environmental impact statement is 
required.

List of Subjects in 21 CFR Part 558

    Therefore, under the Federal Food, Drug, and Cosmetic Act and under 
authority delegated to the Commissioner of Food and Drugs and 
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:

Cosmetic Act (21 U.S.C. 360b, 371).

Sec. 558.342  [Amended]

    2. Section 558.342 Melengestrol acetate is amended in paragraph
