(e) Concentrated oils and feed additive premixes containing vitamins A, D and/or E may, at the option of the distributor be stated in units per gram instead of units per pound.

(f) Vitamin B-12, in milligrams or micrograms per pound.

(g) All other vitamin guarantees shall express the vitamin activity in milligrams per pound in terms of the following: Menadione, riboflavin, d-pantothenic acid, thiamine, niacin, vitamin B-6, folic acid, choline, biotin, inositol, p-amino benzoic acid, ascorbic acid, and carotene.

(4) Guarantees for drugs shall be stated in terms of percent by weight, except:

(a) Antibiotics, present at less than two thousand grams per ton (total) of commercial feed shall be stated in grams per ton of commercial feed.

(b) Antibiotics present at two thousand or more grams per ton (total) of commercial feed, shall be stated in grams per pound of commercial feed.

(c) Labels for commercial feeds containing growth promotion and/or feed efficiency levels of antibiotics, which are to be fed continuously as the sole ration, are not required to make quantitative guarantees except as specifically noted in the Federal Food Additive Regulations for certain antibiotics, wherein, quantitative guarantees are required regardless of the level or purpose of the antibiotic.

(d) The term "milligrams per pound" may be used for drugs or antibiotics in those cases where a dosage is given in "milligrams" in the feeding directions.

(5) Commercial feeds containing any added nonprotein nitrogen shall be labeled as follows:

(a) For ruminants:

(i) Complete feeds, supplements, and concentrates containing added nonprotein nitrogen and containing more than 5 percent protein from natural sources shall be guaranteed as follows: Crude protein, minimum, ___ percent (this includes not more than ___ percent equivalent crude protein from nonprotein nitrogen).

(ii) Mixed feed concentrates and supplements containing less than 5 percent protein from natural sources may be guaranteed as follows: Equivalent crude protein from nonprotein nitrogen, minimum, ___ percent.

(iii) Ingredient sources of nonprotein nitrogen such as urea, diammonium phosphate, ammonium polyphosphate solution, ammoniated rice hulls, or other basic nonprotein nitrogen ingredients defined by the Association of American Feed Control Officials shall be guaranteed as follows: Nitrogen, minimum, ___ percent equivalent crude protein from nonprotein nitrogen, minimum, ___ percent.

(b) For nonruminants:

(i) Complete feeds, supplements and concentrates containing crude protein from all forms of nonprotein nitrogen, added as such, shall be labeled as follows: Crude protein, minimum ___ percent (this includes not more than ___ percent equivalent crude protein which is not nutritionally available to species of animal for which feed is intended).

(ii) Premixes, concentrates or supplements intended for nonruminants containing more than 1.25 percent equivalent crude protein from all forms of nonprotein nitrogen, added as such, must contain adequate directions for use and a prominent statement:

WARNING: This feed must be used only in accordance with directions furnished on the label.

(6) Mineral phosphatic materials for feeding purposes shall be labeled with the guarantee for minimum and maximum percentage of calcium (when present), the minimum percentage of phosphorus, and the maximum percentage of fluorine.

(7) Guarantees for microorganisms shall be stated in colony forming units per gram (CFU/g) when directions are for using the product in grams, or in colony forming units per pound (CFU/lb.) when directions are for using the product in pounds. A parenthetical statement following the guarantee shall list each species in order of predominance.

(8) Guarantees for enzymes shall be stated in units of enzymatic activity per unit weight or volume, consistent with label directions. The source organism for each type of enzymatic activity shall be specified, such as: Protease (Bacillus subtilis) 5.5 mg amino acids liberated/min./milligram. If two or more sources have the same type of activity, they shall be listed in order of predominance based on the amount of enzymatic activity provided.

(9) Guarantees for dietary starch, sugars, and fructans for commercial feeds, other than customer-formula feed, pet food and specialty pet food products:

(a) A commercial feed which bears on its labeling a claim in any manner for levels of "dietary starch," "sugars," "fructans," or words of similar designation, shall include on the label:

(i) Guarantees for maximum percentage of dietary starch and maximum percentage sugars, in the guaranteed analysis section immediately following the last fiber guarantee.

(ii) A maximum percentage guarantee for fructans immediately following sugars, if the feed contains forage products.

(b) When such guarantees for dietary starch, sugars or fructans for commercial feeds appear on the label, feeding directions shall indicate the proper use of the feed product and a recommendation to consult with a veterinarian or nutritionist for a recommended diet.

(10) The labels on commercial feeds such as vitamin/mineral premix and base mix intended as a specialized nutritional source for use in the manufacture of other feeds, must state the intended purpose and guarantee that the nutrients are relevant to that purpose.

(11) When approved by the department, guarantees may be made for these special feeds even if there are no approved Association of Official Analytical Chemists (AOAC) methods for determining specific nutritional content of these specialized feeds.

(12) The sliding scale method of expressing a guaranteed analysis on a commercial feed label (for example "minimum crude protein 15-18 percent") is prohibited.

(13) Minerals, except salt, when quantitatively guaranteed, must be stated in terms of percentage of the element.

(14) Guaranteed analysis for all grain mixture, with or without molasses, commercial feed must include the following nutrients on the label in the order listed:

(a) Minimum percentage of crude protein;

(b) Minimum percentage of crude fat; and

(c) Maximum percentage of crude fiber.
