ROVABIO EXCEL in poultry feeds
Excel improves the nutritional value of layer
feeds by increasing metabolizable energy
• EXCEL improves the nutritional value of layer
feeds based on wheat
• EXCEL improves the nutritional value of layerfeeds
based on barley
• EXCEL also improves the nutritional value of
layer feeds based on wheat and corn
Validation in experimental farms:
• EXCEL improves
layer performances with wheat-based feed
• Interaction with
feed physical form: mash vs crumbles
• Comparaison of
wheat/barley
Conclusion: How to use Rovabio Excel?
ROVABIO EXCEL in poultry
feeds
Rovabio EXCEL improves the nutritional value of feeds containing
arabinoxylans or glucans.
This improvement will be evaluated by digestibility tests
on feeds with or without Rovabio.
The consequences on growth or laying performances will be
measured by zootechnical trials run in experimental stations.

Conclusion: How to use
Rovabio Excel?
- No limit of incorporation of wheat or barley in the feed
- More flexibility for the formulation.
- With the choice of:
- on the top
or
- reduce the energy specification of the feed:
- wheat based diet: + 30 Kcal ME/lb
- barley based diet: + 50 Kcal ME/lb
or
- reevaluate cereal energy value:
- wheat: + 4 %
- barley: + 8 to 9 %
