Improve productivity with Hemicell™ XT

Optimal productivity depends on maximising the energy available in feed


The cost of feed vs. productivity underpins the profit margin of poultry production. Measured by key metrics such as FCR and EPEF managing and maximising the nutritional margins of feed is therefore a powerful way to increase profitability.

Beta-mannans have a negative impact on productivity:

Reduced feed efficiency icon

Reduce feed efficiency by diverting energy towards an unnecessary immune response1-5 and negatively impacting gut health and function6,7

% feed icon

Consume up to 3% of the metabolisable energy in feed8

Increased feed cost icon

Increased feed costs to maintain performance9 - Specifically a higher requirement for expensive protein and fat sources required for energy.

Hemicell XT eliminates the damaging effects of beta-mannans8

As a beta-mannanase enzyme, Hemicell XT breaks down beta-mannans before they are able to prompt a damaging immune response.8

Maintain performance on reduced feed costs1-5

With and without Hemicell diagram

Providing assured return on investment

Hemicell XT makes more energy available from the same amount of feed:

Unlocks up to an additional 90 kcal of metabolisable energy from the diet by preventing its loss to an unnecessary immune response9

Reduce feed cost icon

Reduces feed costs whilst maintaining performance9


Make beta-mannan reduction your dietary standard with Hemicell XT


Hemicell XT: a different type of enzyme

white lightning icon
Energy-sparing…

Hemicell XT:

Stops unnecessary, energy-wasting processes, allowing more energy already in the feed to be directed towards growth and productivity

Black and white lightening icon
… not energy releasing

Other enzymes:

Work to ‘open up’ feed components that the animal is unable to access on its own
