(A) The percentage value in the product name of a commercial feed shall signify only crude protein, and/or equivalent crude protein content, unless otherwise qualified. Digital numbers may be used as long as they are not used in such a manner as to mislead or confuse the customer.
(B) No person shall include in the product name of a commercial feed:
(1) The word "protein", if the feed contains non-protein nitrogen;
(2) The name of any ingredient to the exclusion of other ingredients provided that if any ingredient is intended to impart a distinctive characteristic to the product which is of significance to the purchaser, the name of that ingredient or combination of ingredients may be used in a manner that is not otherwise false of misleading;
(3) The word "vitamin", any contraction thereof, or any word suggesting vitamin content unless the product is represented to be a vitamin supplement and the label includes the minimum content of each vitamin declared;
(4) The word "mineralized", except in the product name "trace mineralized salt".
(C) 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 mixture labeled "dairy feed", for example, must be suitable for that purpose.
(D) Commercial, 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.
(E) 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 director designates otherwise.
(F) The term "meat" or "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.
