DEPARTMENT OF HEALTH AND HUMAN SERVICES

21 CFR Part 558


New Animal Drugs for Use in Animal Feeds; Melengestrol and 
Tylosin

AGENCY: Food and Drug Administration, HHS.

ACTION: Final rule; technical amendment.

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

SUMMARY: The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of an abbreviated new animal drug 
application (ANADA) filed by Ivy Laboratories, Division of Ivy Animal 
Health, Inc. The ANADA provides for use of single-ingredient Type A 
medicated articles containing melengestrol and tylosin to make two-way 
combination Type C medicated feeds for heifers fed in confinement for 
slaughter.

DATES: This rule is effective May 12, 2006.

FOR FURTHER INFORMATION CONTACT: Daniel A. Benz, Center for Veterinary 
Medicine (HFV-104), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0223, e-mail: daniel.benz @fda.hhs.gov.

SUPPLEMENTARY INFORMATION: Ivy Laboratories, Division of Ivy Animal 
Health, Inc., 8857 Bond St., Overland Park, KS 66214, filed ANADA 200-
427 for use of HEIFERMAX 500 (melengestrol acetate) Liquid Premix and 
TYLAN (tylosin phosphate) single-ingredient Type A medicated articles 
to make two-way combination Type C medicated feeds for heifers fed in 
confinement for slaughter. Ivy Laboratories' ANADA 200-427 is approved 
as a generic copy of Pharmacia and Upjohn Co.'s new animal drug 
application (NADA) 139-192 for combination use of MGA 500 (melengestrol 
acetate) Liquid Premix and TYLAN in cattle feed. The application is 
approved as of April 19, 2006, and the regulations are amended in 21 
CFR 558.342 to reflect the approval. The basis of approval is discussed 
in the freedom of information summary.
    In addition, FDA has found that the April 1, 2005, edition of title 
21, parts 500 to 599 of the Code of Federal Regulations (CFR) does not 
accurately reflect the approved conditions of use for melengestrol and 
tylosin. This error was inadvertently included in the 2002 codification 
of a supplement for the pioneer application (67 FR 47687, July 22, 
2002). At this time, Sec.  558.342 is being amended to correct this 
error. This action is being taken to improve the accuracy of the 
regulations.
    In accordance with the freedom of information provisions of 21 CFR 
part 20 and 21 CFR 514.11(e)(2)(ii), a summary of safety and 
effectiveness data and information submitted to support approval of 
this application may be seen in the Division of Dockets Management 
(HFA-305), Food and Drug Administration, 5630 Fishers Lane, rm. 1061, 
Rockville, MD 20852, between 9 a.m. and 4 p.m., Monday through Friday.
    The agency has determined under 21 CFR 25.33(a)(2) 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.
    This rule does not meet the definition of ``rule'' in 5 U.S.C. 
804(3)(A) because it is a rule of ``particular applicability.'' 
Therefore, it is not subject to the congressional review requirements 
in 5 U.S.C. 801-808.

Therefore, under the Federal Food, Drug, and Cosmetic Act and under

redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is 
amended as follows:
