18. Non-Protein NitrogenNote: 1. All products must have the prescribed NPN warnings on labels Note: 2. The label must include guarantees for protein (min), moisture (max), protein equivalent and all other nutriets as specified in these definitions. Use only in mixed feeds for ruminants (cattle, sheep and goats) Warning: Do not feed to animals producing milk for human consumption 18.1 Urea must contain not less than 460 g/kg nitrogen (equivalent to 287% crude protein) The free ammonia level may not exceed 0,3 g/kg and the biuret level may not exceed 15 g/kg. Iron, arsenic and lead content must be in accordance with Annexure 4 and must form part of the guarantees. Altogether 85% of the particles shall ideally between 0,5 – 2 mm. The maximum formaldehyde content is 0,5 g/kg.
18.3 Ammonium chloride, is the product resulting from the neutralisation of hydrochloric acid with ammonia generally expressed as NH4Cl. It must contain not less than 256 g/kg nitrogen (equivalent to 160% crude protein). It must contain not more than 1 g/kg moisture, 4 g/kg salt (NaCI), 15 ppm iron (Fe), 3 ppm arsenic (As), and 10 ppm heavy metals reported as lead. It may be treated with not more than 10 g/kg tricalcium phosphate to prevent caking. It shall not be made from byproduct ammonia recovered from coke oven gas. It is to be used only in feeds for cattle and sheep as a source of non-protein nitrogen at a level not to exceed 10 g/kg ammonium chloride in the total daily ration to provide not more than 1.6% equivalent crude protein. Labels for feed containing ammonium chloride include premixes, concentrates and supplements shall contain adequate directions for use and the prescribed warnings. 18.4 Ammonium sulphate is the product resulting from the neutralization of sulphuric acid with ammonia. It shall contain not less than 210 g/kg nitrogen (N) and not less than 240 g/kg sulphur (S). It shall contain not more than 15 ppm arsenic (As) and 30 ppm heavy metals reported as lead. This does not include ammonium sulphate made from byproduct ammonia recovered from coke-oven gas. It shall be used only in ruminant feeds as a source of sulphur and nitrogen. The label must have adequate directions for use and the prescribed NPN warnings. 18.5 Mono ammonium phosphate is the product resulting from the neutralisation of phosphoric acid, feed grade, or defluorinated wet-process phosphoric acid which contains not less than 90 g/kg nitrogen (N) and 230 g/kg phosphorus (P). . It shall be used only in ruminant feeds as a source of phosphorus and nitrogen. The label shall have adequate directions for use and the prescribed NPN warnings. 19. Oat ProductsNote: 1. The maximum moisture must not exceed 120 g/kg The label shall include guarantees for protein (min), moisture (max), fibre (max) and fibre (min) and (max) for products rich in fibre. 19.1 Oat groats is cleaned oats with the hulls removed. 19.2 Oat hulls consists primarily of the outer covering of oats, obtained in the milling of table cereals or in the groating of oats from clean oats. 19.3 Oat meal is obtained in the manufacture of rolled oat groats or rolled oats and consists of broken oat groats, oat groat chips, and floury portions of the oat groats, with only such quantity of finely ground oat hulls as is unavoidable in the usual process of commercial milling. It must not contain more than 40 g/kg crude fibre. 20. OilseedsNote: 1. Cake is an unground form of an oilseed product Note: 2. The label must have guarantees for minimum protein, maximum fibre and maximum moisture.
