Current through Register Vol. 47, No. 6, September 18, 2024

Cornmercial feed, other than customer-formula feed, shall be labeled with the information prescribed in this regulation.

(1) Product name and brand name if any.

a. The brand or product name must be appropriate for the intended use of the feed and must not be misleading. If the name indicates the feed is made for a specific use, the character of the feed must conform therewith. A Cornmercial feed for a particular animal class must be suitable for that purpose.

b. Cornmercial, registered brand or trade names are not permitted in guarantees or ingredient listings and only in the product name of feeds produced by or for the firm holding the rights to such a name.

c. The name of a Cornmercial feed shall not be derived from one or more ingredients of a mixture to the exclusion of other ingredients and shall not be one representing any Cornponents of a mixture unless all Cornponents are included in the name; provided, that if any ingredient or Cornbination of ingredients is intended to impart a distinctive characteristic to the product which is of significance to the purchaser, the name of that ingredient or Cornbination of ingredients may be used as a part of the brand name or product name if the ingredients or Cornbination of ingredients is quantitatively guaranteed in the guaranteed analysis and the brand or product name is not otherwise false or misleading.

d. The word "protein" shall not be permitted in the product name of a feed that contains added nonprotein nitrogen.

e. When the name carries a percentage value, it shall be understood to signify protein or equivalent protein content only, or both, even though it may not explicitly modify the percentage with the word "protein," provided, that other percentage values may be permitted if they are followed by the proper description and conform to good labeling practice. Digital numbers shall not be used in such a manner as to be misleading or confusing to the customer

f. Single-ingredient feeds shall have a product name in accordance with the designated definition of feed ingredients as recognized by the Association of American Feed Control Officials unless the secretary designates otherwise.

g. The word "vitamin," or a contraction thereof, or any word suggesting "vitamin" can be used only in the name of a feed which is represented to be a vitamin supplement, and which is labeled with the minimum content of each vitamin declared, as specified in 41.4(3).

h. The term "mineralized" shall not be used in the name of a feed except for "TRACE MINERALIZED SALT." When so used, the product must contain significant amounts of trace minerals which are recognized as essential for animal nutrition.

i. The term "meat" and "meat by-products" shall be qualified to designate the animal from which the meat and meat by-products are derived unless the meat and meat by-products are made from cattle, swine, sheep and goats.

c. The purpose statement may be excluded from the label if the product name includes a description of the species and animal class(es) for which the product is intended.

d. The purpose statement of a premix for the manufacture of feed may exclude the animal class and species and state "For Further Manufacture of Feed" if the nutrients contained in the premix are guaranteed and sufficient for formulation into various animal species feeds and premix specifications are provided by the end user of the premix. (This paragraph is applicable to Cornmercial feeds regulated under 41.3(4)7"(2)"10.")

e. The purpose statement of a single-purpose ingredient blend, such as a blend of animal protein products, milk products, fat products, roughage products or molasses products may exclude the animal class and species and state "For Further Manufacture of Feed" if the label guarantees of the nutrients contained in the single-purpose nutrient blend are sufficient to provide for formulation into various animal species feeds. (This paragraph is applicable to Cornmercial feeds regulated under 41.3(4) 7 "(2)"10.")
