SUBJECT CATEGORY: New Animal Drugs for Use in Animal Feeds; Narasin and Bacitracin Zinc
DOCUMENT SUMMARY: The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a new animal drug application (NADA) filed by Roche Vitamins, Inc. The NADA provides for use of approved narasin and bacitracin zinc Type A medicated articles to make twoway combination Type C medicated feeds used for prevention of coccidiosis, increased rate of weight gain, and improved feed efficiency in broiler chickens.
SUMMARY: Narasin and bacitracin zinc,
Section 558.78 is also amended editorially to consolidate the crossreferences for approved combinations in paragraph (d)(3) and list them in alphabetical order.
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 (HFA305), 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. 801808.
