The product 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 Maximum content of element (Zn) in mg/kg of complete feedingstuff with a moisture content of 12 % Category of nutritional additives. Functional group: compounds of trace elements 3b611 — Zinc chelate of methionine (1:2) Characterisation of the additive Powder with a minimum content of 78 % DL-methionine and a zinc content between 17,5 % and 18,5 % Characterisation of the active substance Zinc chelate of methionine: Zinc-Methionine 1:2 (Zn(Met) 2 ) Chemical formula: C 10 H 20 N 2 O 4 S 2 Zn CAS number: 151214-86-7 Analytical methods ( 1 ) For the quantification of methionine in feed additive: — ISO/CD 17180: ion exchange chromatography method with post-column derivatisation and photometric or fluorometric detection. For the quantification of total zinc in the feed additive and premixtures: — EN 15510: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES), or — CEN/TS 15621: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES) after pressure digestion. For the quantification of total zinc in the feedingstuffs: — Commission Regulation (EC) No 152/2009 ( 2 ) — Atomic Absorption Spectrometry (AAS), or — EN 15510: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES), or — CEN/TS 15621: Inductively Coupled Plasma — Atomic Emission Spectrometry (ICP-AES) after pressure digestion. All species — Pets: 250 (total) Fish: 200 (total) Other species: 150 (total) Complete and complementary milk replacers: 200 (total) 1. The additive shall be incorporated into the feed in form of a premixture. 2. For user safety: breathing protection, safety glasses and gloves should be worn during handling. 3. The contribution of the additive to the dietary supply with methionine should be taken into account. 22 July 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 ( 2 ) OJ L 54, 26.2.2009, p. 1 .
