1.
The L-lysine content shall be indicated on the labelling of the additive.
2.
Declarations to be made on the labelling of the additive and premixtures: ‘The supplementation with L-lysine should take into account all essential and conditional essential amino acids in order to avoid imbalances.’
3.
The endotoxin content of the additive and its dusting potential shall ensure a maximal endotoxin exposure of 1 600 IU endotoxins/m 3 air ( 2 ) .
4.
For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks by inhalation. Where those risks cannot be eliminated or reduced to a minimum level by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including skin, eyes and breathing protection.

Characterisation of the active substance
L-lysine sulphate produced by fermentation with Escherichia coli CGMCC 7.398
Chemical formula: C 12 H 28 N 4 O 4 -O 4 S
CAS number: 60343-69-3
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
For the identification of sulphate in the feed additive:
—
European Pharmacopoeia Monograph 20301
For the quantification of lysine in premixtures, compound feed and feed materials:
—
ion exchange chromatography coupled with post-column derivatisation and optical detection (IEC-VIS) – Commission Regulation (EC) No 152/2009 (Annex III, F).
