HAS ADOPTED THIS REGULATION:
| 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 |
|---|---|---|---|---|---|---|---|---|---|
| Selenium in mg/kg of complete feed with a moisture content of 12 % | |||||||||
| 3b817 | — | Selenomethionine produced by Saccharomyces cerevisiae NCYC R645(Selenised yeast inactivated) | Characterisation of the additive:Preparation of organic selenium:Content of selenium: 2000 to 2400 mg Se/kgOrganic selenium > 98 % of total seleniumSelenomethionine > 70 % of total seleniumCharacterisation of the active substance:Selenomethionine produced by Saccharomyces cerevisiae NCYC R645Chemical formula: C5H11NO2SeAnalytical methodnote:For the determination of selenomethionine in the feed additive:reversed phase high performance liquid chromatography with UV detection (RP-HPLC-UV), orhigh performance liquid chromatography and inductively coupled plasma mass spectrometry (HPLC-ICPMS) after triple proteolytic digestion.For the determination of total selenium in the feed additive:inductively coupled plasma atomic emission spectrometry (ICP-AES), orinductively coupled plasma mass spectrometry (ICPMS).For the determination of total selenium in premixtures, compound feed and feed materials: hydride generation atomic absorption spectrometry (HGAAS) after microwave digestion (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 shall be worn during handling.3.Technological additives or feed materials included in the preparation of the additive shall ensure a dusting potential < 0,2 mg selenium/m3 air.4.In the directions for use of the additive and premixtures, indicate the storage and stability conditions.5.Maximum supplementation with organic selenium:0,20 mg Se/kg of complete feed with a moisture content of 12 %. | 13 April 2025 |
