Nonprotein Nitrogen

PURPOSE: This rule defines use limitations and correct labeling procedures for nonprotein nitrogen. (1) Urea and other nonprotein nitrogen products defined in 2 CSR 70-30.015 are acceptable ingredients only in commercial feeds for ruminant animals as a source of equivalent crude protein. If the commercial feed contains more than eight and three-fourths percent (8.75%) 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 (1/3) 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 will be read and understood by ordinary persons under customary conditions of purchase and use. (2) Nonprotein nitrogen products defined in 2 CSR 70-30.015, when so indicated, are acceptable ingredients in commercial feeds distributed to nonruminant animals as a source of nutrient other than equivalent crude protein. The maximum equivalent crude protein from nonprotein nitrogen sources, when used in nonruminant rations, shall not exceed one and one-fourth percent (1.25%) of the total daily ration. (3) On labels such as those for medicated feeds which bear adequate feeding directions, 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 the product due to the presence of nonprotein nitrogen.
