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.

Excel improves the nutritional value of broiler feed by increasing metabolizable energy


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 %
