Additive composition

Preparation of:

Fermentation product of Aspergillus oryzae NRRL 458: 4 to 5 %

Wheat bran: 94 to 95 %

Solid form.

Characterisation of the active substance

Endo-1,4-beta-glucanase (EC 3.2.1.4) and alpha-amylase (EC 3.2.1.1) having respectively a minimum activity of 14,5 mU  ( 1 ) /g and 20 mIU  ( 2 ) /g.

Analytical method

( 3 )

For the quantification of endo-1,4-beta-glucanase in the feed additive: colorimetric method based on the enzymatic reaction by endo-1,4-beta-glucanase on a CellG5 substrate.

For the quantification of alpha-amylase in the feed additive: colorimetric (DNS) method based on the enzymatic reaction by alpha-amylase on a potato starch substrate.

1.

In the directions for use of the additive and premixture, the storage conditions and stability to heat treatment shall be indicated.

2.

Recommended dose: the quantity of the additive in daily ration should be 3 to 5 g/cow/day.

3.

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 protective equipment.

( 1 )   One CellG5 Unit (U) is the amount of enzyme in the presence of excess thermostable beta-glucosidase, required to release one micromole of 4-nitrophenol from CellG5 in one minute under the defined assay conditions.

( 2 )   One unit of alpha-amylase activity (IU) refers to the amylase that liberates 1 micromole of glucose per minute from potato starch at pH 6,9 and at 38 °C.
