The preparation specified in the Annex, belonging to the additive category ‘nutritional additives’ and to the functional group ‘compounds of trace elements’, is authorised as an additive 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 Content of element (Se) in mg/kg of complete feed with a moisture content of 12 % Category of nutritional additives. Functional group: compounds of trace elements 3b814 — Hydroxy-analogue of selenomethionine Characterisation of the additive Solid and liquid preparation of Hydroxy-analogue of selenomethionine Content of selenium: 18 000 to 24 000 mg Se/kg Organic selenium > 99 % of total Se Hydroxy-analogue of selenomethionine > 98 % of total Se Solid preparation: 5 % Hydroxy-analogue of selenomethionine and 95 % carrier Liquid preparation: 5 % Hydroxy-analogue of selenomethionine and 95 % distilled water Characterisation of the active substance Organic selenium from hydroxy-analogue of selenomethionine (R,S-2-hydroxy-4-methylselenobutanoic acid) Chemical formula: C 5 H 10 O 3 Se CAS number 873660-49-2 Analytical method ( 1 ) For the determination of hydroxy analogue of methionine in the feed additive: — High performance liquid chromatography coupled to UV detection at 220 nm (HPLC-UV) For the determination of total selenium in the feed additive: — Inductively coupled plasma mass spectrometry (ICPMS) after microwave digestion with HNO 3 /H 2 O 2 , or — Inductively coupled plasma atomic emission spectrometry (ICPAES) after digestion with HNO 3 /HCl For the determination of total selenium in premixtures and feed: — Hydride generation atomic absorption spectrometry (HGAAS) after microwave digestion with HNO 3 /H 2 O 2 (EN 16159:2012) All species — 0,50 (total) 1. The additive shall be incorporated into feed in the form of a premixture. 2. For user safety: breathing protection, safety glasses and gloves should be worn during handling. 3. Maximum supplementation with organic selenium: 0,20 mg Se/kg of complete feed with a moisture content of 12 %. 4 June 2023 ( 1 ) Details of the analytical methods are available at the following address of the Reference Laboratory: http://irmm.jrc.ec.europa.eu/EURLs/EURL_feed_additives/authorisation/evaluation_reports/Pages/index.aspx
