ROVABIO EXCEL in poultry feeds
Excel improves the nutritional value of broiler
feed by increasing metabolisable energy
Validation in several experimental farms:
France: Customer
experimental farm
France: Adisseo
experimental farm
Spain: IRTA (wheat-based
diet)
Spain: IRTA (barley-based
diet)
UK: Customer experimental
farm (wheat-based diet)
Germany: Martin-Luther
University (wheat-based diet)
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.

Digestibility methodology - growing
broilers
|
- Ad-libitum feeding:
- 0-16 days Standard feed
- 17-28 days Feed with / without enzyme
- 3 days adaptation
- 4 days excreta collection
- Plan design:
- 1 broiler per cage
- 12 replicates per treatment
(12 Broilers / treatment)
|
- Collection of excreta daily
twice a day
- Analytical measurements
- Feed intake per cage
- Individual weight gain
- Gross energy of feeds
- Gross energy of excreta

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: + 36 Kcal ME/lb
- barley-based diet: + 64 Kcal ME/lb
or
- reevaluate cereal energy value:
-wheat: + 5 %
-barley: + 8 to 10 %
