NAC587.590. Nonprotein nitrogen: Restrictions; precautions.

     1. Urea and other nonprotein nitrogen products defined in the official publication of the Association are acceptable ingredients only in commercial feeds for ruminant animals as a source of equivalent crude protein and are not to be used in commercial feeds for other animals and birds.

     2. If the commercial 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 must 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 must be in type of such size so placed on the label that they will be read and understood by ordinary persons under customary conditions of purchase and use.

     3. On labels such as those for medicated feeds which bear adequate feeding directions or warning statements, the presence of added nonprotein nitrogen does 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.
