animal drug application (ANADA) filed by Ivy Laboratories, Division of 
Ivy Animal Health, Inc. The supplemental ANADA provides for use of

FOR FURTHER INFORMATION CONTACT: John K. Harshman, Center for 
Veterinary Medicine (HFV-170), Food and Drug Administration, 7500

SUPPLEMENTARY INFORMATION: Ivy Laboratories, Division of Ivy Animal 
Health, Inc., 8857 Bond St., Overland Park, KS 66214, filed a 
supplement to ANADA 200-422 for use of HEIFERMAX 500 (melengestrol 
acetate) and RUMENSIN (monensin, USP) single-ingredient Type A 
medicated articles to make two-way, combination drug Type C medicated 
feeds for heifers fed in confinement for slaughter. The supplemental 
ANADA provides for use of increased dose levels of melengestrol acetate 
and monensin. The supplemental application is approved as of July 1, 
2011, and the regulations in 21 CFR 558.342 are amended to reflect the 
approval and minor revisions.
    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 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.
