Authorisation
The substance specified in the Annex, belonging to the additive category ‘nutritional additives’ and to the functional group ‘amino acids, their salts and analogues’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
Entry into force
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.
ANNEX Identification number of the feed additive Name of the additive Composition, chemical formula, description, analytical method Species or category of animal Maximum age Minimum content Maximum content Other provisions End of period of authorisation mg/kg of complete feed with 12 % moisture content Category: nutritional additives. Functional group: amino acids, their salts and analogues 3c374i L-valine Additive composition L-valine with a minimum content of 98 % (on a dry matter basis). Solid form. Characterisation of the active substance L-valine produced with Corynebacterium glutamicum KCCM 80365 IUPAC name: ((2S)-2-amino-3-methylbutanoic acid) Chemical formula: C 5 H 11 NO 2 CAS number: 72-18-4 Analytical method ( 1 ) For the identification of L-valine in the feed additive: — Food Chemical Codex ‘L-valine monograph’ For the determination of valine in the feed additive: — Ion-exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS) For the determination of valine in premixtures and compound feed: — Ion-exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS), Commission Regulation (EC) No 152/2009 ( 2 ) For the determination of valine in water for drinking: — Ion-exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS or IEC-VIS/FLD) All animal species - - - 1. In the directions for use of the additive and premixtures, the storage conditions, the stability to heat treatment and the stability in water for drinking shall be indicated. 2. The additive may be used via water for drinking. 3. Feed business operators shall ensure that L-valine is rumen protected, when fed to ruminants. 4. The moisture content shall be indicated on the label of the additive. 5. The label of the additive and premixtures shall indicate the following: ‘The supplementation with L-valine, in particular via water for drinking, shall take into account all essential and conditionally essential amino acids in order to avoid nutritional imbalances.’ 8 January 2036 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: https://joint-research-centre.ec.europa.eu/eurl-fa-eurl-feed-additives/eurl-fa-authorisation/eurl-fa-evaluation-reports_en .
