Section 35:30-27-7 - Non-protein nitrogen

(a) Urea and other non-protein nitrogen products defined in the Official Publication of the Association of American Feed Control Officials are acceptable ingredients only in commercial feeds for ruminant animals as a source of equivalent crude protein. If the commercial feed contains more than 8.75% of equivalent crude protein from all forms of non-protein nitrogen added, or the equivalent crude protein from all forms of non-protein nitrogen, added as such, exceeds one-third of the total crude protein, the label shall bear adequate directions for the safe use of feeds and a precautionary statement: "CAUTION: USE AS DIRECTED". The directions for use and the caution statement shall be in type of a size so placed on the label that they shall be read and understood by persons purchasing and using the product.

(b) Non-protein nitrogen defined in the Official Publication of the Association of American Feed Control Officials, when so indicated, are acceptable ingredients in commercial feeds distributed to non-ruminant animals as a source of nutrients other than equivalent crude protein. The maximum equivalent crude protein from non-protein nitrogen sources when used in non-ruminant rations shall not exceed 1.25% of the total daily ration.

(c) On labels for medicated and added non-protein nitrogen feeds, which bear adequate feeding directions and/or warning statements about the presence of added drugs and/or non-protein nitrogen, shall not require a duplication of the feeding directions. The precautionary statements shall include sufficient information to ensure the safe and effective use of these products.
