THE MOST HEAT RESISTANT XYLANASE
GENERATES THE MOST ENERGY
MAXIMISE NSP UTILISATION TO IMPROVE
FCR AND REDUCE COSTS
ECONASE XT INFLUENCES NUTRIENT DIGESTION
TO INCREASE USABLE ENERGY
•Energy is the most expensive nutrient in the diet – 100 Kcal/Kg currently costs approximately US$10/tonne
In broilers, Econase XT:
•Using NSPases creates an opportunity for nutritionists and feed producers to maximise energy
utilisation from the diet
•Reduces digesta viscosity
WHY CHOOSE XYLANASE?
•Improves nutrient digestibility
•Influences intestinal
fermentation
THE PREBIOTIC EFFECT OF ARABINOXYLAN OLIGOSACCHARIDES (AXOS)
•Approximately 45% of the NSP composition of corn and wheat-based diets consists
of arabinoxylans, making them the largest NSP component in raw materials
•Xylanase is the NSPase that breaks down arabinoxylans into beneficial arabinoxylan
oligosaccharides (AXOS), helping to improve animal performance
•Econase XT influences intestinal fermentation by producing favourable prebiotic
xylo-oligomers in the lower GI
•These xylo-oligomers can increase volatile fatty acid production, shift the microbial
profile and provide valuable energy for intestinal cells

ECONASE XT – THE XYLANASE THAT DELIVERS OPTIMAL
NSP BREAKDOWN FOR IMPROVED ENERGY UTILISATION
A beta 1-4 endo-xylanase that optimises the breakdown of NSP,
reducing its anti-nutritive effects and improving the energy utilisation
of monogastric diets
* Wheat and barley diets.

WHY DOES AXOS MATTER?
THE ONLY XYLANASE THAT IS
INTRINSICALLY THERMOSTABLE
XYLANASES DIFFER IN THEIR ABILITY TO BREAK DOWN ARABINOXYLANS
•
ECONASE XT SURVIVES THE RIGOURS OF THE FEED CONDITIONING PROCESS
Different xylanases produce different AXOS profiles
•
•Xylose (X1) can have a negative effect on animal performance and energy utilisation[Shuttle et al 1991]
while X3–X7 can have a positive effect
Econase XT
Pelleting conditions vary dramatically between feed mills and within the same feed mill
•Selecting a xylanase that can withstand the rigors of the feed conditioning process is
critical to ensure consistent performance improvements
Econase XT is the only xylanase that
is intrinsically thermostable
