DEPARTMENT OF HEALTH AND HUMAN SERVICES
21 CFR Part 558
New Animal Drugs for Use in Animal Feeds; Monensin
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 supplemental new animal drug
application (NADA) filed by Elanco Animal Health, Division of Eli Lilly
and Co. The supplemental NADA provides for use of an approved monensin
Type A medicated article to make a revised formulation of a monensin
Type C medicated feed/free-choice mineral granule fed to pasture cattle
for increased rate of weight gain.
EFFECTIVE DATE: December 12, 1995.
FOR FURTHER INFORMATION CONTACT: David R. Newkirk, Center for
Veterinary Medicine (HFV-142), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 301-594-2701.
SUPPLEMENTARY INFORMATION: Elanco Animal Health, Division of Eli Lilly
and Co., Lilly Corporate Center, Indianapolis, IN 46285, filed
supplemental NADA 95-735, which provides for use of 80 grams(g) per
pound monensin Type A articles to make a monensin Type C medicated
feed/free-choice mineral granule containing 1,620 g per ton monensin.
The Type C feed/free-choice mineral granules are fed to pasture cattle
(slaughter, stocker, feeder, and dairy and beef replacement heifers)
for increased rate of weight gain. The supplemental NADA provides for a
revised formulation Type C free-choice mineral granule. The revised
formulation does not affect the safety or effectiveness data and
information upon which the application is approved. The supplemental
NADA is approved as of December 12, 1995, and the regulations are
amended in 21 CFR 558.355 by adding new paragraph (f)(3)(x) to reflect
the approval.
Use of a Type A medicated article to make a free-choice Type C
medicated feed/ mineral granule requires an approved Form FDA 1900 as
in 21 CFR 510.455.
Under section 512(c)(2)(F)(iii) of the Federal Food, Drug, and
Cosmetic Act (21 U.S.C. 360b(c)(2)(F)(iii)), this approval does not
qualify for marketing exclusivity because the supplement does not
contain reports of new clinical or field investigations or new human
food safety studies (other than bioequivalence or residue studies)
essential to the approval and conducted or sponsored by the applicant.
A freedom of information summary for this approval is not required
because it involves approval of a revised formulation which does not
affect the basis of approval of the product. A summary of the data and
information submitted to support the original approval may be seen in
the Dockets Management Branch (HFA-305), Food and Drug Administration,
rm. 1-23, 12420 Parklawn Dr., Rockville, MD 20857, between 9 a.m. and 4
p.m., Monday through Friday.
The agency has determined under 21 CFR 25.24(d)(1)(iii) 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.
List of Subjects in 21 CFR Part 558
Animal drugs, Animal feeds.
Therefore, under the Federal Food, Drug, and Cosmetic Act and under
the authority delegated to the Commissioner of Food and Drugs and
redelegated to the Center for Veterinary Medicine, 21 CFR part 558 is
amended as follows:

(f) * * *
(3) * * *
(x) Amount per ton. Monensin, 1,620 grams as monensin sodium (810
milligrams per pound).
(a) Indications for use. For increased rate of weight gain.
(b) Specifications. Use as free-choice Type C medicated feed
formulated as mineral granules as follows:-
----------------------------------------------------------------------------------------------------------------
Ingredient Percent International feed no.
----------------------------------------------------------------------------------------------------------------
Monocalcium phosphate (21% phosphorus, 15% calcium) 29.49 6-01-080
Sodium chloride (salt) 24.25 6-04-152
Dried cane molasses 20.0 4-04-152
Ground limestone (33% calcium) 13.75 6-02-632
Cane molasses 3.0 4-04-696
Processed grain by-products (as approved by AAFCO) 5.0
Vitamin/trace mineral premix\1\ 2.5
Monensin Type A article, 80 grams per pound 1.01
Antidusting oil 1.0
----------------------------------------------------------------------------------------------------------------
\1\Content of the vitamin/trace mineral premix may be varied. However, they should be comparable to those used
for other free-choice feeds. Formulation modifications require FDA approval prior to marketing. The amount of
selenium and ethylenediamine dihydroiodide (EDDI) must comply with the published requirements. (For selenium
see 21 CFR 573.920; for EDDI see 51 FR 11483 (April 3, 1986).)
(c) Limitations. Medicated mineral granules to be fed free-choice
to pasture cattle (slaughter, stocker, feeder, and dairy and beef
replacement heifers) weighing more than 400 pounds. Feed continuously
on a free-choice basis at the 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 water deprived
cattle should be adapted to the pasture and to unmedicated mineral
supplement before using this product. Do not feed to lactating dairy
cattle. Do not allow horses, other equines, mature turkeys, or guinea
fowl access to feed containing monensin. Ingestion of monensin by
horses and guinea fowl has been fatal. The product's effectiveness in
cull cows and bulls has not been established. Each use of this free-
choice Type C feed must be the subject of an approved medicated feed
application (MFA or Form FDA 1900) or supplemental MFA as required by
Sec. 510.455 of this chapter.
