21 CFR Part 558

New Animal Drugs for Use in Animal Feeds; Narasin and Tylosin Phosphate

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 new animal drug application (NADA) filedby Elanco Animal Health. The NADA provides for use of approved, single-ingredient narasin and tylosin phosphate Type A medicated articles to make two-way combination Type C medicated feeds used as an aid in the prevention of coccidiosis, for increased rate of weight gain, and improved feed efficiency in broiler chickens.

DATES: This rule is effective November 1, 2000.

FOR FURTHER INFORMATION CONTACT: Charles J. Andres, Center for Veterinary Medicine (HFV-128), Food and Drug Administration, 7500 Standish Pl., Rockville, MD 20855, 301-827-1600.

SUPPLEMENTARY INFORMATION: Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filedNADA 141-170 that provides for use of MONTEBAN(36, 45, 54, 72, or 90 grams per pound (g/lb) narasin activity) and TYLAN(10 g/ lb of tylosin phosphate) Type A medicated articles to make combination Type C medicated broiler chicken feeds. The combination Type C medicated feeds contain 54 to 72 g/ton narasin and 4 to 50 g/ton tylosin phosphate and are used for the prevention of coccidiosis caused by Eimeria necatrix, E. tenella, E. acervulina, E. brunetti, E. mivati, and E. maxima, increased rate of weight gain, and improved feed efficiency in broiler chickens. The NADA is approved as of September 20, 2000, and the regulations in Secs. 558.363 and 558.625 (21 CFR 558.363 and 558.625) are amended 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 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 Dockets Management Branch (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.
