Division 4.10.1 Techniques for reducing nitrogen excreted
United Kingdom
| Regulation (EC) No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition (OJ L 268, 18.10.2003, p. 29). | |
| Technique | Description |
|---|---|
| Reduce the crude protein content by using a N-balanced diet based on the energy needs and digestible amino acids. | Reduce excesses in the crude protein supply by ensuring that it does not exceed feeding recommendations. The diet is balanced to meet the animal requirements of energy and digestible amino acids. |
| Multiphase feeding with a diet formulation adapted to the specific requirements of the production period. | The feed mix matches the animal requirements more accurately in terms of energy, amino acids and minerals, depending on the animal weight and/or production stage. |
| Addition of controlled amounts of essential amino acids to a low crude protein diet. | A certain amount of protein-rich feedstuffs is substituted by low-protein feedstuffs, in order to further reduce the crude protein content. The diet is supplemented with synthetic amino acids (e.g. lysine, methionine, threonine, tryptophan, valine) so that there is no deficiency in the amino acid profile. |
| Use of authorised feed additives which reduce total nitrogen excreted. | Authorised (according to Regulation (EC) No 1831/2003 of the European Parliament and of the Councilf1 substances, microorganisms or preparations such as enzymes (e.g. NSP enzymes, proteases) or probiotics are added to feed or water in order to favourably affect feed efficiency e.g. by improving the digestibility of feedstuffs or affecting the gastrointestinal flora. |
