Authorisation
The preparation specified in the Annex, belonging to the additive category ‘zootechnical additives’ and to the functional group ‘digestibility enhancers’, is authorised as an additive in animal nutrition, subject to the conditions laid down in that Annex.
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.
ANNEX Identification number of the additive Name of the holder of authorisation 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 Units of activity/kg of complete feedingstuff with a moisture content of 12 % Category of zootechnical additives. Functional group: digestibility enhancers 4a45 Elanco GmbH Endo–1,4-beta-mannanase (EC 3.2.1.78) Additive composition: Preparation of endo–1,4-beta-mannanase produced by Paenibacillus lentus DSM 33618 having a minimum activity of 1,60 × 10 5 U ( 1 ) /g, and ≤ 1 % food-grade mineral oil Solid form. Characterisation of the active substance: Endo–1,4-beta-mannanase (EC 3.2.1.78) produced by Paenibacillus lentus DSM 33618 Analytical method ( 2 ) : For the quantification of endo–1,4-beta-mannanase activity in the feed additive, premixtures and compound feed: colorimetric methods based on enzymatic hydrolysis and the reaction of reducing sugars (mannose equivalent) with 3,5-dinitrosalicylic acid (DNS) Chickens for fattening Chickens reared for laying Minor poultry species for fattening Minor poultry species reared for laying or breeding Pigs for fattening Minor porcine species for fattening — 32 000 U — 1. In the directions for use of the additive and premixture, 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 breathing and skin protective equipment. 19 December 2033 Turkeys for fattening Turkeys reared for breeding Weaned piglets Weaned piglets of minor porcine species 48 000 U ( 1 ) One unit of endo-1,4-beta-mannanase activity (U) is the amount of the enzyme which generates 0,72 micrograms of reducing sugars per minute from a mannose containing substrate at pH 7,0 and 40 °C.
