Expression of guarantees

1. The guarantees for crude protein, equivalent protein from nonprotein nitrogen, crude fat, crude fiber, and mineral guarantees (when required) will be in terms of percentage. 2. Commercial feeds containing six and one-half percent or more calcium, phosphorus, sodium, and chloride shall include in the guaranteed analysis the minimum and maximum percentages of calcium (Ca), the minimum percentage of phosphorus (P), and if salt is added, the minimum and maximum percentage of salt (NaCl). Minerals, except salt (NaCl), shall be guaranteed in terms of percentage of the element. When calcium or salt, or both, guarantees are given in the guaranteed analysis such must be stated and conform to the following: a. When the minimum is five percent or less, the maximum may not exceed the minimum by more than one percentage point. b. When the minimum is above five percent, the maximum shall not exceed the minimum by more than twenty percent and in no case may the maximum exceed the minimum by more than five percentage points. 3. Guarantees for minimum vitamin content of commercial feeds must be listed in the order specified and are stated in milligrams per pound unless otherwise specified: a. Vitamin A, other than precursors of vitamin A, in international units per pound. b. Vitamin D-3 in products offered for poultry feeding, in international chick units per pound. c. Vitamin D for other uses, international units per pound. d. Vitamin E, in international units per pound. e. Concentrated oils and feed additive premixes containing vitamins A, D, or E, or a combination thereof, 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; riboflavine; d-pantothenic acid; thiamine; niacine; vitamin B-6; folic acid, chloline, biotin, inositol; p-amino benzoic acid; ascorbic acid; and carotene. 4. Guarantees for drugs must be stated in terms of percent by weight, except: a. Antibiotics, present at less than two thousand grams per ton (total) of commercial feed must be stated in grams per ton of commercial feed. b. Antibiotics present at two thousand or more grams per ton (total) of commercial feed, must be stated in grams per pound of commercial feed. c. Labels for commercial feeds containing growth promotion or feed efficiency, or both, 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 must be labeled as follows: a. For ruminants: (1) Complete feeds, supplements, and concentrates containing added nonprotein nitrogen and containing more than five percent protein from natural sources shall be guaranteed as follows: Crude Protein, minimum, -----% (This includes not more than -----% equivalent protein from nonprotein nitrogen). (2) Mixed feed concentrates and supplements containing less than five percent protein from natural sources may be guaranteed as follows: Equivalent Crude Protein from Nonprotein Nitrogen, minimum, -----% (3) Ingredient sources of nonprotein nitrogen such as urea, di-ammonium 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, -----% Equivalent Crude Protein from Nonprotein Nitrogen, minimum, -----% b. For nonruminants: (1) Complete feeds, supplements, and concentrates containing crude protein from all forms of nonprotein nitrogen, added as such, must be labeled as follows: Crude protein, minimum, -----% (This includes not more than -----% equivalent crude protein which is not nutritionally available to (species of animal for which feed is intended). (2) Premixes, concentrates, or supplements intended for nonruminants containing more than one and one-quarter percent equivalent crude protein from all forms of nonprotein nitrogen, added as such, must contain adequate directions for use and prominently state: WARNING: This feed must be used only in accordance with directions furnished on the label. 6. Mineral phosphatic materials for feeding purposes must 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 micro-organisms must 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 must list each species in order of predominance.
