The substances specified in the Annex, belonging to the category ‘nutritional additives’ and the functional group ‘amino acids, their salts and analogues’, are authorised as feed additives in animal nutrition, subject to the conditions laid down in that Annex.
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 additive Name of the holder of authorisation 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 additive/kg of complete feed with a moisture content of 12 % Category of nutritional additives. Functional group: amino acids, their salts and analogues. 3c320 - L-lysine base, liquid Additive composition: Aqueous solution of L-lysine with a minimum of 50 % L-lysine. All species - - - 1. The lysine content shall be indicated on the labelling of the additive. 2. L-lysine base, liquid, may be placed on the market and used as an additive consisting of a preparation. 3. The additive can be also used via water for drinking. 4. Declarations to be made on the labelling of the additive and premixtures: ‘The supplementation with L-lysine, in particular via water for drinking, should take into account all essential and conditionally essential amino acids in order to avoid imbalances.’ 5. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address the potential risks by inhalation, eye or dermal contact. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment, including breathing protection, safety glasses and gloves. 16 May 2031 Characterisation of the active substance: L-lysine produced by fermentation with Corynebacterium casei KCCM 80190 Chemical formula: NH 2 -(CH 2 ) 4 -CH(NH 2 )-COOH CAS Number: 56-87-1 Analytical methods ( 1 ) : For the quantification of lysine in the feed additive and premixtures containing more than 10 % lysine: — ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS/FLD) – EN ISO 17180.
