Food and Drug Administration, HHS.
The Food and Drug Administration (FDA) is amending the animal drug regulations to reflect approval of a supplemental new animal drug application (NADA) filed by Elanco Animal Health. The supplemental NADA provides for use of monensin Type A medicated article to make Type C medicated feed formulated as mineral granules for free-choice feeding for the prevention and control of coccidiosis, and increased rate of weight gain in pasture cattle (slaughter, stocker, feeder, and dairy and beef replacement heifers). A technical correction is also being made.

Elanco Animal Health, A Division of Eli Lilly & Co., Lilly Corporate Center, Indianapolis, IN 46285, filed supplemental NADA 95-735 that provides for use of RUMENSIN® 80 (80 grams per pound (g/lb) of monensin as monensin sodium) Type A medicated article to make Type C medicated feed formulated as mineral granules for free-choice feeding to pasture cattle. The free-choice medicated mineral granules contain 1,620 g/ton monensin and are used for prevention and control of coccidiosis caused by Eimeria bovis and E. zuernii, and for increased rate of weight gain in pasture cattle (slaughter, stocker, feeder, and dairy and beef replacement heifers). The supplemental NADA is approved as of July 7, 2000, and the regulations are amended in § 558.355(f)(3)(x) (21 CFR 558.355(f)(3)(x)) to reflect the approval. The basis of approval is discussed in the freedom of information summary.
In addition, § 558.355(d)(6) is revised to reflect current precautionary statements regarding the ingestion of monensin-containing formulations by unapproved species. Start Printed Page 45880
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)(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.Start List of Subjects

(a) Indications for use. For increased rate of weight gain; and for prevention and control of coccidiosis caused by Eimeria bovis and E. zuernii in pasture cattle (slaughter, stocker, feeder, and dairy and beef replacement heifers).
(c) Limitations. For free-choice feeding to pasture cattle (slaughter, stocker, feeder, and dairy and beef replacement heifers) at a rate of 50 to 200 milligrams per head per day. During the first 5 days of feeding, cattle should receive no more than 100 milligrams per day. Do not feed additional salt or minerals. Do not mix with grain or other feeds. Monensin is toxic to cattle when consumed at higher than approved levels. Stressed and/or feed- and/or water-deprived cattle should be adapted to the pasture and to unmedicated mineral supplement before using the monensin mineral supplement. Do not feed to lactating dairy cattle. The product's effectiveness in cull cows and bulls has not been established. Consumption by unapproved species may result in toxic reactions. A feed manufacturing facility must possess a medicated feed mill license issued under § 515.20 of this chapter in order to manufacture this free-choice Type C feed.
