Article 1The preparation belonging to the group "Enzymes", as specified in Annex I, is authorised for use without a time limit as an additive in animal nutrition under the conditions laid down in that Annex.
Article 2The preparation belonging to the group "Enzymes", as specified in Annex II, is provisionally authorised for four years as an additive in animal nutrition under the conditions laid down in that Annex.
Article 3The preparation belonging to the group "Micro-organisms", as specified in Annex III, is authorised provisionally for four years as an additive in animal nutrition under the conditions laid down in that Annex.
Article 4This Regulation shall enter into force on the third day following that of its publication in the Official Journal of the European Union.
This Regulation shall be binding in its entirety and directly applicable in all Member States.ANNEX I
