Description
What it is. This is an enzyme additive, cellulase (EC 3.2.1.4), produced by fermentation using the filamentous fungus Trichoderma longibrachiatum strain ATCC PTA-10001. It belongs to the functional group of silage additives (technological additives, category 1k) and is characterised by its catalytic activity hydrolysing cellulose.
What it is for. Cellulases of this type are generally used as silage additives to support fibre breakdown and improve fermentation conditions during ensiling. They would typically act on structural carbohydrates (cellulose) in the forage, facilitating sugar release for lactic fermentation. This functional group is intended for use on plant material before or during ensiling, across animal species as listed, rather than as a direct feed additive for finished diets. No specific dose or species-stage recommendation is given in the sources.
Points to watch. Authorisation under this entry ended on 11 April 2019; current status should be checked before any use or reference. No maximum inclusion level is available from the sources, and dose, pH and moisture conditions in the silage mass affect enzyme performance. Activity is temperature- and storage-sensitive; conditions should follow supplier specifications.
