3b509 | - | Manganese chelate of lysine and glutamic acid | Additive composition:Preparation of chelates of manganese with lysine and chelates of manganese with glutamic acid in a ratio of 1:1 as a powder witha manganese content between 15 and 17 %,a lysine content between 20 and 21,5 %,a glutamic acid content between 22 and 24 %,a maximum of 3,5 % moisture anda maximum of 4 ppm nickel. | All animal species | - | - | Fish: 100 (total)Other species: 150 (total) | - 1.The additive shall be incorporated into feed in the form of a premixture.
- 2.For users of the additive and premixtures, feed business operators shall establish operational procedures and appropriate organisational measures to address the potential risks by inhalation, dermal contact or eyes contact, in particular due to the content of heavy metals including nickel. Where risks cannot be reduced to an acceptable level by these procedures and measures, the additive and premixtures shall be used with appropriate personal protective equipment, including eyes, skin and breathing.

Analytical methods:For the quantification of total manganese in the feed additive and premixtures:- Atomic Absorption Spectrometry, AAS (EN ISO 6869); or
- Inductively Coupled Plasma – Atomic Emission Spectrometry, ICP-AES (EN 15510); or
- Inductively Coupled Plasma – Atomic Emission Spectrometry after pressure digestion, ICP-AES (EN 15621);
For the quantification of total manganese in feed materials and compound feed:- Atomic Absorption Spectrometry, AAS (Commission Regulation (EC) No 152/2009, Annex IV-C); or
- Atomic Absorption Spectrometry, AAS (EN ISO 6869); or
- Inductively Coupled Plasma – Atomic Emission Spectrometry, ICP-AES (EN 15510); or
- Inductively Coupled Plasma – Atomic Emission Spectrometry after pressure digestion, ICP-AES (EN 15621).
For the quantification of the lysine and glutamic acid content in the feed additive:- ion exchange chromatography coupled with post-column derivatisation and photometric detection (IEC-VIS)
For proving the chelated structure of the feed additive:- mid-infrared (IR) spectrometry together with the determination of the content of the trace element and lysine and glutamic acid in the feed additive
