LegalizeCommission Implementing Regulation (EU) 2025/161 of 29 January 2025 concerning the authorisation of a preparation of muramidase produced with Trichoderma reesei DSM 32338 as a feed additive for laying hens (holder of authorisation: DSM Nutritional Products Ltd, represented by DSM Nutritional Products Sp. z o.o.)
Article 1
Authorisation
The preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and to the functional group ‘other zootechnical additives’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
Article 2
Entry into force
This Regulation shall enter into force on the twentieth 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.

| 4d16 | Novozymes A/S | Muramidase (EC 3.2.1.17) | Additive composition Preparation of muramidase (EC 3.2.1.17) produced with Trichoderma reesei DSM 32338 having a minimum activity of 60 000 LSU(F) (1)/g. Solid and liquid forms. Characterisation of the active substance Muramidase (EC 3.2.1.17, also known as ‘lysozyme’) produced with Trichoderma reesei DSM 32338 Analytical method (2) For the quantification of muramidase: fluorescence-based enzyme assay method that determines the enzyme-catalyzed depolymerisation of a fluorescein-labelled peptidoglycan preparation at pH 6,0 and 30 °C. | Laying hens | — | 30 000 LSU(F) | 60 000 LSU(F) | 1. In the directions for use of the additive and premixtures, the storage conditions and stability to heat treatment shall be indicated. 2. For users of the additive and premixtures, feed business operators shall establish operational procedures and organisational measures to address potential risks resulting from their use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal skin and breathing protective equipment, as well as personal eye protective equipment for the solid form of the additive. | 19 February 2035 |
| (1) One LSU(F) is defined as the amount of enzyme that increases the fluorescence of 12,5 μg/ml fluorescein-labelled peptidoglycan per minute at pH 6,0 and 30 °C by a value that corresponds to the fluorescence of approximately 0,06 nmol fluorescein isothiocyanate isomer. (2) 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 |
