(a) The brand name and product name of any commercial feed shall be appropriate for the intended use of the feed and shall not be misleading. If either such name indicates the feed is made for a specific use, the character of the feed shall conform therewith; for example, a mixture labeled “dairy feed” shall be suitable for that purpose.

(b) Commercial, brand or trade names shall not be permitted in any guaranteed analysis or ingredient listing.

(c) The name of any commercial feed shall not be derived from one or more ingredients of a mixture to the exclusion of other ingredients and shall not represent any components of a mixture unless all components are included in the name; provided, that if any ingredient or combination 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 combination of ingredients may be used as a part of the brand name or product name if the ingredient or combination of ingredients is quantitatively guaranteed in the guaranteed analysis, and the brand name or product name is not otherwise false or misleading.

(d) The word “protein” shall not be permitted in the product name of any feed that contains added non-protein nitrogen.

(e) When the brand name or product name carries a percentage value, it shall signify actual protein and/or equivalent protein content only, 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. When a figure is used in any brand name (except in mineral, vitamin, or other products where the protein guarantee is nil or unimportant), it shall be preceded by the word “number” or some other suitable designation.

(f) Single ingredient feeds shall have a product name in accordance with the official definitions of feed ingredients as recognized by AAFCO unless the commissioner prescribes otherwise.

(g) The word “vitamin”, or any 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 provided in section 257.4(c) of this Part.

(h) The term “mineralized” shall not be used in the name of any feed, except for “trace mineralized salt”. When the latter expression is used, the product shall contain significant amounts of trace minerals which are recognized as essential for animal nutrition.

(i) The terms “meat” and “meat by-products” shall be qualified to designate the animal from which the meat or meat by-products are derived unless the meat or meat by-products are from cattle, swine, sheep and goats.
