Commission Implementing Regulation (EU) 2016/1964 of 9 November 2016 concerning the authorisations of a preparation of dolomite-magnesite for dairy cows and other ruminants for dairy production, weaned piglets and pigs for fattening and a preparation of montmorillonite-illite for all animal species as feed additives (Text with EEA relevance )
The preparation specified in the Annex I, belonging to the additive category ‘technological additives’ and to the functional group ‘anti-caking agents’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
The preparation specified in the Annex II, belonging to the additive category ‘technological additives’ and to the functional groups ‘anti-caking agents’ and ‘binders’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
This Regulation shall enter into force on the twentieth day following that of its publication in the Official Journal of the European Union.

1.
For use in weaned piglets until 35 kg.
2.
In the labelling of the additive and premixtures containing it, the following shall be indicated: ‘The additive dolomite-magnesite is rich in (inert) iron’.
3.
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.

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’.
