# Commission Implementing Regulation (EU) 2020/2120 of 16 December 2020 amending Implementing Regulation (EU) 2016/1964 as regards the authorisation of a preparation of montmorillonite-illite as feed additive for all animal species (Text with EEA relevance), Annex Extent: E+W+S+N.I. In the Annex to Implementing Regulation (EU) 2016/1964, the entry concerning the additive montmorillonite-illite with the identification number 1g557 is replaced by the following: Details of the analytical methods are available at the following address of the Reference Laboratory: https://ec.europa.eu/jrc/en/eurl/feed-additives/evaluation-reports Identification number of the additive 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 mg of additive/kg of complete feedingstuff with a moisture content of 12 % Category of technological additives.

The instructions for use shall indicate the following: “The simultaneous oral use with macrolides shall be avoided”, ”In addition, for poultry, the simultaneous use with robenidine shall be avoided”. 2.. For poultry: the simultaneous oral use with coccidiostats other than robenidine is contraindicated with level of montmorillonite-illite above 10 000 mg/kg of complete feed. 3.. In the labelling of feed additive and premixtures containing it, the following shall be indicated: “The additive, montmorillonite-illite, is rich in (inert) iron”. 4.. 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 or reduced to a minimum by such procedures and measures, the additive and premixtures shall be used with personal protective equipment, including breathing protection 5.. total amount of different sources of montmorillonite-illite in complete feedingstuff shall not exceeded the permitted maximum level of 20 000 mg/kg of complete feedingstuff. 30 November 2026’ Analytical method For the determination in feed additive: X-ray diffraction (XRD) Inductively coupled plasma atomic emission spectroscopy (ICP-AES) Details of the analytical methods are available at the following address of the Reference Laboratory: https://ec.europa.eu/jrc/en/eurl/feed-additives/evaluation-reports Identification number of the additive 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 mg of additive/kg of complete feedingstuff with a moisture content of 12 % Category of technological additives.
