What is Hemicell XT and how does it work?

Hemicell XT is a new nutrient-sparing enzyme for pig and poultry producers. This gut-health-enhancing supplement supports nutrient uptake and has the potential to reduce overall feed costs due to the improved utilisation of dietary energy.

Most plant-based raw materials contain β-mannans, undigestible fibres that monogastric livestock cannot breakdown. When β-mannans are found in a ration, energy that should be used for growth, is diverted towards a Feed-Induced Immune Response (FIIR) to these fibres, impairing bird performance potential. Hemicell XT offers a solution and advanced formulation compared to existing market options.

The energy-sparing enzyme performs in the same way as Hemicell HT but it contains an upgraded carrier that is proven to further enhance diet quality. This change to the formulation allows for improved flowability and mixing within a ration. It results in a larger, more uniform particle size, offering greater uniformity and reduced dust during application.

Making application easier

Hemicell XT also has an enzyme concentration 2.25 times higher than the original Hemicell HT formulation. This accommodates a wide range of application methods, including within complete feeds, premix and speciality mixes.

In the current climate, the use of Hemicell HT in premixed ration formulations is less convenient. But the increased concentration and therefore lower dose of Hemicell XT means it takes up half the storage and transportation space as the original Hemicell HT formulation, increasing the flexibility.
