Semduramicin sodium (Aviax 5 %) Additive composition Preparation of: — Mycelium: 166–333 g/kg additive, containing 48,7–53,9 g semduramicin sodium, — food grade mineral oil: 30–50 g/kg additive, — sodium carbonate: 40 g/kg additive, — sodium aluminosilicate: 20 g/kg additive, — Soybean mill run: quantum satis. Solid form. Characterisation of the active substance Semduramicin sodium: — C 45 H 75 O 16 Na — CAS number: 119068-77-8 — sodium {(2R,3S,4S,5R,6S)-2,4-dihydroxy-6-[(1R)-1-{(2S,5R,7S,8R,9S)-9-hydroxy-2-[(2S,2’R,3’S,5R,5’R)-5’-[(2S,3S,5R,6S)-6-hydroxy-3,5,6-trimethyloxan-2-yl]-3’-{[(2S,5S,6R)-5-methoxy-6-methyloxan-2-yl]oxy}-2-methyl[2,2’-bioxolan]-5-yl]-2,8-dimethyl-1,6-dioxaspiro[4.5]decan-7-yl}ethyl]-5-methoxy-3-methyloxan-2-yl}acetate Produced from Actinomadura spp. ATCC 53664. Related impurities: semduramicin epimer, semduramicin aglycon (without G ring), desmethyl semduramicin (A ring), desmethyl semduramicin (G ring), hydroxyl semduramicin (F ring), desmethoxyl semduramicin (A ring) and descarboxyl semduramicin: < 3 % each. Total impurities: ≤ 7 %. Analytical methods  ( 1 ) For the quantification of semduramicin sodium in the feed additive and premixtures: High Performance Liquid Chromatography using post-column derivatisation coupled with photometric detection (HPLC-PCD-UV-Vis). For the quantification of semduramicin sodium in compound feeds: — High Performance Liquid Chromatography using single mass spectrometry (HPLC-MS) or post-column derivatisation coupled with photometric detection (HPLC-PCD-UV-Vis) – EN 16158, or — High performance liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) – EN 17299. Chickens for fattening — 20 25 1. In the directions for use of the additive and premixture, the storage conditions and stability to heat treatment shall be indicated. 2. The additive shall be incorporated in compound feed in the form of a premixture. 3. Semduramicin sodium shall not be mixed with other coccidiostats. 4. The following shall be indicated on the label of the additive, as well as of premixtures and compound feed containing it: ‘This feedingstuff contains an ionophore: simultaneous use with tiamulin is contra-indicated’. 5. A post-market monitoring programme on the resistance of Eimeria spp. to semduramicin sodium shall be planned and executed by the holder of authorisation, in accordance with Commission Regulation (EC) No 429/2008  ( 2 ) . 6. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from its use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal breathing, eye and skin protective equipment. 30 September 2034 ( 1 )   Details of the analytical methods are available at the following address of the Reference Laboratory: https://joint-research-centre.ec.europa.eu/eurl-fa-eurl-feed-additives/eurl-fa-authorisation/eurl-fa-evaluation-reports_en .
