3b411 | — | Copper bilysinate | Characterisation of the additivePowder or granulate with a content of copper ≥ 14,5 % and lysine-HCl ≥ 84,0 %.Characterisation of the active substanceCopper chelate of L-lysinate-HClChemical formula: Cu(C6H13N2O2)2 × 2HClCAS number: 53383-24-7Analytical methods:For the quantification of Lysine content in the feed additive:- Ion-exchange chromatography combined with post-column derivatisation and colorimetric or fluorescence detection — EN ISO 17180.
For the quantification of total copper content in the feed additive and premixtures:- 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 copper in the feed materials and compound feed:- Atomic absorption spectrometry (AAS) — Commission Regulation (EC) No 152/2009, 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.
| All animal species | — | — | Bovines:- bovines before the start of rumination: 15 (total),
- other bovines: 35 (total).
Ovines: 15 (total).Piglets up to 12 weeks: 170 (total).Crustaceans: 50 (total).Other animals: 25 (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.The following words shall be included in the labelling:- For feed for sheep if the level of copper in the feed exceeds 10 mg/kg:"The level of copper in this feed may cause poisoning in certain breeds of sheep."
- For feed for bovines after the start of rumination if the level of copper in the feed is less than 20 mg/kg:"The level of copper in this feed may cause copper deficiencies in cattle grazing pastures with high contents of molybdenum or sulphur."
- "The lysine content of the additive should be considered when formulating feed."
