New Animal Drugs For Use in Animal Feeds; Ractopamine
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 two supplemental new animal drug applications (NADAs) filed by Elanco Animal Health. The first supplemental NADA revises the concentrations of ractopamine hydrochloride in single-ingredient Type B and C medicated swine feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness. The other supplemental NADA revises the concentrations of ractopamine hydrochloride used with tylosin phosphate in two-way Type C medicated swine feeds to conform with approved single-ingredient ractopamine use.
DATES: This rule is effective November 21, 2006.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed a supplement to NADA 140-863 that provides for use of PAYLEAN (ractopamine hydrochloride) Type A medicated articles in Type B and C medicated feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness in finishing swine. The supplement revises the concentrations of ractopamine hydrochloride fed to finishing swine, weighing not less than 150 pounds, fed a complete ration containing at least 16 percent crude protein for the last 45 to 90 pounds of gain prior to slaughter. This supplemental NADA was approved on April 25, 2006. 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 supplemental approval qualifies for 3 years of marketing exclusivity beginning April 25, 2006.
Elanco Animal Health also filed a supplement to NADA 141-172 that provides for use of two-way combination Type C medicated swine feeds formulated with PAYLEAN (ractopamine hydrochloride) and TYLAN (tylosin phosphate) single-ingredient Type A medicated articles. The supplement revises the concentrations of ractopamine hydrochloride in Type C medicated feeds used for increased rate of weight gain, improved feed efficiency, and increased carcass leanness; and for prevention and/or control of porcine proliferative enteropathies (ileitis) associated with Lawsonia intracellularis and for prevention of swine dysentery (vibrionic) in finishing swine, weighing

not less than 150 pounds, fed a complete ration containing at least 16 percent crude protein for the last 45 to 90 pounds of gain prior to slaughter. This supplemental NADA is approved as of October 20, 2006, and the regulations in 21 CFR 558.500 are amended to reflect both approvals. The basis of these approvals is discussed in the freedom of information summaries.
In accordance with the freedom of information provisions of 21 CFR part 20 and 21 CFR 514.11(e)(2)(ii), summaries of safety and effectiveness data and information submitted to support approval of these applications 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.
FDA has determined under 21 CFR 25.33(a)(1) that these actions are of a type that do 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.
