Functional group: digestibility enhancers 4a3i 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 32052) having a minimum activity of 7,2 × 10 5 U ( 1 ) /ml Liquid form Characterisation of the active substance Endo-1,4-beta-mannanase produced by Paenibacillus lentus (DSM 32052) Analytical method ( 2 ) colorimetric method based on the reaction between reducing sugars (mannose equivalent) with 3,5-dinitrosalicylic acid (DNS) Chickens for fattening - 79 200 U - 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 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. 26.2.2030 Turkeys for fattening Chickens reared for laying Turkeys reared for breeding Minor poultry species for fattening or reared for laying/breeding ( 1 ) One unit of activity (U) is the amount of the enzyme which liberates 0,72 micrograms of reducing sugars (mannose equivalents) from a mannan-containing substrate (locust bean gum) per minute at pH 7,5 and 40 °C.
