| Description
Rovabio™ Excel AP is a concentrated powder whose main
enzymatic activities are xylanase and ß-glucanase obtained
from a fermentation broth of Penicillium funiculosum.
This product hydrolyzes pentosans and ß glucans in plant
raw materials.
Effect :
- Improves the nutritional value of feeds containing different
types of cereals (corn, wheat, triticale, rye, barley, etc.)
and oilseed meals (soybean, sunflower, canola, etc.)
- Reduces gut viscosity
- Reduces the free ammonia concentration in the litter
Composition
Main active substances:
Endo - 1,4 - ß - xylanase : N° EC 3.2.1.8.
Endo - 1,3 (4) - ß - glucanase : N° EC 3.2.1.6.
Other enzyme activities : Cellulases

1 unit of endo 1,4 - ß - xylanase is defined as
the amount of enzyme which will
hydrolyze the substrate, reducing the viscosity of the solution,
to give a change in
relative fluidity of 1 (dimensionless unit)/mn/g of enzyme
under the conditions of the
assay (viscometer developed by Orange Leaf Company).
1 AXC unit is defined as the release of oligomers from
of chromophore-bound xylan
which are not precipitable by ethanol, equivalent to an absorbance
of 1.23 units at
590 nm.
1 AGL unit is defined as the release of oligomers from
a chromophore-bound glucan
which are not precipitable by ethanol, equivalent to an absorbance
of 0.82 at 590 nm.
Duration of Guarantee
12 months within the manufacturing date, in closed packaging,
below 30 °C (86 °F) and protected from humidity.
Packaging
25 kg bag (500 kg/pallet)

into feeds
Methods of Analysis
Method for endo - 1,4 - ß - xylanase activity:
Reference: RPCL - Q4.50 – issue 2.4
- The assay is based on the enzymatic hydrolysis of a standard
wheat arabinoxylan solution, the activity being determined
by the reduction in relative viscosity (viscometer developed
by Orange Leaf Company).
Reference: RPCL - Q4.33 - issue 3.3
- Measuring absorbance at 590 nm enables endo-1,4-b-xylanase
activity to be determined by a colorimetric method with
a chromophore substratum.
Method for endo - 1,3 (4) - ß-glucanase activity
Reference: RPCL - Q4.32 – issue 4.1
- Measuring absorbance at 590 nm enables endo - 1,3 (4)–ß-glucanase
activity to be determined by a colorimetric method with
a chromophore substratum.
Method for Cellulase DNS CMC activity
Reference Q4.22B – issue 3.6
- The reaction, catalyzed by cellulase, involves the endohydrolysis
of the 1,4- ß-D-glucosidic bonds in cellulose (lichenin
and cereal ß-D-glucans) forming ß-1,4 glucan
oligosaccharides.
Assay methods available upon request.
Safety

Handling of the product may cause allergic reactions by inhalation.
Use in the feed: once incorporated into the feed, the product
offers all original guarantees of safety.
