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 4a42 Kerry Ingredients and Flavours Ltd Endo–1,4 -beta-mannanase (EC 3.2.1.78) Additive composition: Preparation of endo–1,4 -beta-mannanase produced by Aspergillus niger CBS 120604 having a minimum activity of 265 U ( 1 ) /g solid form Characterisation of the active substance: Endo–1,4 -beta-mannanase (EC 3.2.1.78) produced by Aspergillus niger CBS 120604 Analytical method ( 2 ) : Determination of the endo–1,4 -beta-mannanase activity in the feed additive, premixtures and compound feed: colorimetric method based on the enzymatic reaction of endo–1,4 -beta-mannanase on the azurine cross-linked-carob galactomannan substrate All poultry species for fattening — 30 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 its use. Where those risks cannot be eliminated by such procedures and measures, the additive and premixtures shall be used with personal breathing, eye and skin protective equipment. 10 January 2034 ( 1 ) One endo-1,4-beta-mannanase unit (U) is defined as the amount of enzyme required to release one micromole of mannose reducing sugar equivalents per minute at 40°C and pH 4,5.
