The substances specified in the Annex are authorised as feed additives in animal nutrition in the additive category ‘nutritional additives’, functional group ‘amino acids, their salts and analogues’, 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 ----------------- Characterisation of the active substance: L-lysine produced by fermentation with Corynebacterium glutamicum NRRL-B-67439 or Corynebacterium glutamicum NRRL B-67535.

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. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks by inhalation and for the skin and eyes. Where those risks cannot be eliminated or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing, skin and eye protection. 4. The additive may be also used via water for drinking. 5. 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 conditional essential amino acids in order to avoid imbalances.’ 30.7.2030 3c322 L-lysine monohydrochloride, technically pure Additive composition: Powder of L-lysine monohydrochloride with a minimum of 78 % L-lysine and a maximum moisture content of 1,5 %. ----------------- Characterisation of the active substance: L-lysine monohydrochloride produced by fermentation with Corynebacterium glutamicum NRRL-B-67439 or Corynebacterium glutamicum NRRL B-67535 or Corynebacterium glutamicum CGMCC 7.266.
