Rule 21-41.8 - Nonprotein nitrogen

(1) Urea and other nonprotein nitrogen products defined in the official publication of the Association of American Feed Control Officials are acceptable ingredients only in Cornmercial feeds for ruminant animals as a source of equivalent crude protein. If the Cornmercial feed contains more than 8.75 percent of equivalent crude protein from all forms of nonprotein nitrogen, added as such, or the equivalent crude protein from all forms of nonprotein 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 such size so placed on the label that the directions will be read and understood by ordinary persons under customary conditions of purchase and use.

(2) Nonprotein nitrogen defined in the official publication of the Association of American Feed Control Officials, when so indicated, is an acceptable ingredient in Cornmercial feeds distributed to nonruminant animals as a source of nutrients other than equivalent crude protein. The maximum equivalent crude protein from nonprotein nitrogen sources when used in nonruminant rations shall not exceed 1.25 percent of the total daily ration.

(3) On labels such as those for medicated feeds which bear adequate feeding directions or warning statements, or both, the presence of added nonprotein nitrogen shall not require a duplication of the feeding directions or the precautionary statements as long as those statements include sufficient information to ensure the safe and effective use of this product due to the presence of nonprotein nitrogen.
