21 CFR Parts 520 and 558
[Docket No. FDA-2012-N-0002]
New Animal Drugs for Use in Animal Feeds; Monensin
AGENCY: Food and Drug Administration, HHS.
ACTION: Final rule; technical amendment.
-----------------------------------------------------------------------
SUMMARY: The Food and Drug Administration (FDA) is amending the animal
drug regulations to remove a warning for growing cattle on pasture or
in dry lot and to codify all monensin free-choice Type C medicated
feeds in 21 CFR part 558. This action is being taken to improve the
accuracy of the regulations.
DATES: This rule is effective September 19, 2012.
FOR FURTHER INFORMATION CONTACT: Christina C. Edwards, Center for
Veterinary Medicine (HFV-126), Food and Drug Administration, 7500
Standish Pl., Rockville, MD 20855, 240-276-8228, Email:

SUPPLEMENTARY INFORMATION: FDA has noticed that the animal drug
regulations for certain monensin free-choice Type C medicated feeds for
growing cattle on pasture or in dry lot (slaughter, stocker, and feeder
cattle; and dairy and beef replacement heifers) reflect a warning
statement regarding the overdosing risk posed by uneaten free-choice
feeds (refusals) that is unnecessary and not required on product
labeling.
Refusals of free-choice cattle feeds, including compressed blocks,
granules, and liquids, are unlikely in practice to be fed to another
group of cattle. These products are used almost exclusively in pasture-
based systems where the product is placed in the pasture with the
animals and is left until consumed. In addition, it is extremely
unlikely that these free-choice cattle feeds would be fed to another
production class because these products generally are not appropriate
for the nutritional needs of another production class.
For these reasons, FDA is revising the regulations to exclude
monensin free-choice Type C medicated feeds for growing cattle on
pasture or in dry lot from the requirement to include a warning
statement. This action is being taken to improve the accuracy of the
regulations.
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.

(vii) If feed refusals containing monensin are fed to other groups
of cattle, the concentration of monensin in the refusals and amount of
refusals fed should be taken into consideration to prevent monensin
overdosing (see paragraphs (d)(10)(i) and (d)(10)(ii) of this section).

(i) Cattle (as described in paragraphs (f)(3)(i) through

(d)(7)(v), (d)(7)(vii), and (d)(7)(viii) of this section. Paragraph
(d)(7)(vii) of this section does not apply to free-choice Type C
medicated feeds as defined in Sec. 510.455 of this chapter.
(ii) Dairy cows (as described in paragraphs (f)(3)(xiii) and

(7) Free-choice feeds--(i) Amount. 150 milligrams per pound of
protein-mineral block (0.033 percent).
(a) [Reserved]
(b) Conditions of use--(1) 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) which may require
supplemental feed.
(2) Limitations. Provide 50 to 200 milligrams of monensin (0.34 to
1.33 pounds of block) per head per day, at least 1 block per 10 to 12
head of cattle. Roughage must be available at all times. Do not allow
animals access to other protein blocks, salt or mineral, while being
fed this product. The effectiveness of this block in cull cows and
bulls has not been established. See paragraph (d)(10)(i) of this
section.

(0.088 percent).
(a) Sponsor. See No. 067949 in Sec. 510.600(c) of this chapter.
