Rovabio™ Excel LC is a concentrated solution whose main enzymatic activity is 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
• Reducesthe free ammonia concentration in the litter

COMPOSITION

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

SPECIFICATIONS

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/mL 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 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.

CONDITIONS FOR USE THE PRODUCT

Animal Feeding

• Target species : turkeys, broilers, laying hens, and swine.
• Sprayed onto pelleted feed
• Dose in feed : Xylanase 1 100 unitsvisco.units/kg of feed (equivalent to 70 AXC units/kg)
  ß glucanase: 100 AGL units/kg offeed.

equivalent to 0.2 L (220g) of Rovabio™ Excel LC per tonne of feed or 0.181L (181g) per short ton (2000lbs).

The liquid concentrate can be diluted with water to any desirable quantity before spraying.

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 the Orange Leaf Company).

Reference: RPCL - Q4.33 – issue 3.3

• Measuring absorbance at 590 nm enables endo-1,4- ß -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 achromophore substratum.

Method for cellulase DNS CMC activity
Reference: Q4.22B - issue 3.6

The reaction, catalysed 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

Reference: safety data sheet of Rovabio™ Excel LC version 1.02

Handling of the product may cause allergic reactions by inhalation during spraying.

Use in the feed: once incorporated into the feed, the product offers all original guarantees of safety.
