The present invention relates to a nitrogen-phosphorus feed additive and a process for producing same. In accordance with the present invention, the nitrogen-phosphorus feed additive consists of carbamide, ammonium phosphates, biuret and cyanuric acid at the following proportions of the components, parts by weight: carbamide 25 - 52 ammonium phosphates 27 to 40 biuret 15 to 37 cyanuric acid 0.1 to 9. The process for producing this feed additive comprises heat treatment of 70-79 parts by weight of carbamide along with 21-30 parts by weight of ammonium phosphates at a temperature within the range of from 150 to 180 DEG C with the formation of a melt of the nitrogen-phosphorus feed additive and gaseous products of the reaction, followed by cooling said melt and disintegration thereof, or by granulation of the melt. The present invention is useful in animal breeding. |
