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

SUMMARY:  The Food and Drug Administration (FDA) is amending the animal 
drug regulations to reflect approval of a supplemental abbreviated new 
animal drug application (ANADA) filed by Ivy Laboratories, Division of 
Ivy Animal Health, Inc. The supplemental ANADA provides for the 
addition of tylosin tartrate to an approved subcutaneous implant 
containing trenbolone and estradiol used for increased rate of weight 
gain and improved feed efficiency in steers and heifers fed in 
confinement for slaughter.

DATES:  This rule is effective March 1, 2007.

FOR FURTHER INFORMATION CONTACT:  Eric S. Dubbin, Center for Veterinary 
Medicine (HFV-126), Food and Drug Administration, 7500 Standish Pl., 
Rockville, MD 20855, 301-827-0232, e-mail: [email protected].

SUPPLEMENTARY INFORMATION: Ivy Laboratories, Div. of Ivy Animal Health, 
Inc., 8857 Bond St., Overland Park, KS 66214, filed a supplement to 
ANADA 200-346 for COMPONENT TE-200 with TYLAN (trenbolone acetate and 
estradiol with tylosin tartrate), a subcutaneous implant used for 
increased rate of weight gain and improved feed efficiency in steers 
and heifers fed in confinement for slaughter. The supplemental ANADA 
provides for the addition of a pellet containing 29 milligrams (mg) 
tylosin tartrate to the approved COMPONENT TE-200 implant for steers 
and heifers fed in confinement for slaughter. The supplemental 
application is approved as of January 26, 2007, and the regulations are 
amended in 21 CFR 522.2477 to reflect the approval. The basis of 
approval is discussed in the freedom of information summary.
    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.
    Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and 
Cosmetic Act (the act) (21 U.S.C. 360b(c)(2)(F)(iii)), this approval 
qualifies for 3 years of marketing exclusivity beginning January 26, 
2007.
    The agency has determined under 21 CFR 25.33(a)(1) 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.
