Statements of Calorie Content
PURPOSE: This rule permits a declaration of calorie content to provide better information to pet food purchasers.
(1) The label of a dog or cat food may bear a
statement of calorie content, provided—
(A) The statement shall be separate and
distinct from the “Guaranteed Analysis” and
shall appear under the heading “Calorie
Content”; and
(B) The statement shall be measured in
terms of metabolizable energy (ME) on an
as-fed basis and must be expressed as kilocalories per kilogram (kcal/kg) of product,
and may also be expressed as kilocalories per
familiar household measure (e.g., cups, cans,
ounces, pounds); and
(C) An affidavit shall be provided upon
request by the director, substantiating that the
calorie content was determined—
1. By calculation using the following
“Modified Atwater” formula:
ME (kcal/kg) = 10[(3.5 Ă— CP)
+(8.5 Ă— CF)+(3.5 Ă— NFE)]
where—CP = % crude protein as fed
CF = % crude fat as fed
NFE = % nitrogen-free extract
(carbohydrate) as fed
and the percentages of CP and CF are the
arithmetic averages from proximate analyses
of at least four (4) production batches of the
product, and the NFE is calculated as the difference between one hundred (100) and the
sum of CP, CF and the percentages of crude
fiber, moisture and ash (determined in the
same manner as CP and CF). The results of
all the analyses used in the calculation must
accompany the affidavit, and the claim on the
label or other labeling must be followed parenthetically by the word “calculated”; or
2. In accordance with a testing procedure established by the Association of
American Feed Control Officials. The summary data used in the determination of calorie content must accompany the affidavit.
The value stated on the label shall not exceed
or understate the value determined in accordance with 2 CSR 70-31.080(1)(C)1. by
more than fifteen percent (15%).
(D) Comparative claims shall not be false,
misleading or given undue emphasis and
must be based on the same methodology for
both products.
