| 3b813 | — | Selenomethionine produced by Saccharomyces cerevisiae NCYC R646(Selenised yeast inactivated) | Characterisation of the additivePreparation of organic selenium:Content of selenium: 1000 to 2650 mg Se/kgOrganic selenium > 98 % of total seleniumSelenomethionine > 70 % of total seleniumCharacterisation of the active substanceSelenomethionine produced by Saccharomyces cerevisiae NCYC R646Analytical methodFor the determination of selenomethionine in the feed additive:High 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 mass spectrometry (ICPMS) after microwave digestion with HNO3/H2O2.For the determination of total selenium in premixtures and feed:Hydride generation atomic absorption spectrometry (HGAAS) after microwave digestion with HNO3/H2O2 (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 %. | 29 May 2023 |
