3d1 | — | Urea | - Additive composition:
- Urea content: minimum 97 %
- Nitrogen content: 46 %
- Characterisation of the active substance:Diaminomethanone, CAS number 57-13-6, chemical formula: (NH2)2CO
- Analytical methods:
- For the determination of the total nitrogen in the additive: Titrimetry (method 2.3.3 in Annex IV to Regulation (EC) No 2003/2003)
- For the determination of the biuret contribution to the total nitrogen in the additive: Spectrophotometry (method 2.5 in Annex IV to Regulation (EC) No 2003/2003)
- For the determination of urea in premixtures, compound feed and feed materials: Spectrophotometry (Annex III.D to Regulation (EC) No 152/2009)
| Ruminants with a functional rumen | — | | 8800 | The directions for use of the feed additive and feed containing urea shall include the following:"Urea shall only be fed to animals with a functional rumen. Feeding urea to the maximum level dose should be done gradually. The maximum content of urea should be only fed as part of diets rich in easily digestible carbohydrates and low in soluble nitrogen.A maximum 30 % of total nitrogen in the daily ration should come from urea-N." | 19 November 2022 |
