Proven improvement in fiber degradation

AveMix® XG 10 contains two active enzymes: endo–1,3(4)-beta -glucanase and endo-1,4-beta- xylanase. The synergistic action of these two enzymes ensures the breakdown of both soluble and insoluble non-starch polysaccharide (NSP) fibers that are present in the feed.

This is important as nutrients (i.e., starch, crude proteins, and amino acids) in the small intestine that are trapped in plant cells by insoluble NSP fibers (having a so–called nutshell effect) cannot be absorbed by the animal. Soluble NSP fibers are also an issue as they have a gel effect and high water-binding capacity. This increases gut viscosity which can cause serious health disorders, as well as slowing down and limiting nutrient absorption.

AveMix® XG 10 breaks down the insoluble NSP fibers in plant cell walls, which increases nutrient availability. AveMix® XG 10 also decreases intestinal viscosity by breaking down the soluble NSP fibers, which significantly improves the absorption of nutrients in the small intestine. These beneficial properties of AveMix® XG 10 make it possible to include a higher proportion of fiber-rich raw materials in the feed, including cheaper alternative by-products. This provides flexibility with feed reformulation, which can reduce feed costs.

How does AveMix® XG 10 work?

AveMix® XG 10 is a proven combination of high enzyme activities with superior efficiency to hydrolyze NSP fibers. Enzymes work based on a lock–and–key mechanism where they only act on specific substrates (Figure 1). As such, it is important to know when selecting an enzyme which of the different NSP fibers are present in the feed. For example, NSP fibers are abundant in wheat (9.9%) and corn (8.7%) and these are mainly in the form of arabinoxylans (composed of arabinose and xylose) and glucans (composed of glucose) (Figure 2). AveMix® XG 10 has been specifically formulated to target these main NSP fibers in cereals, with guaranteed high activity levels of endo-1,4-β-xylanase and endo-1,3(4)-β-glucanase enzymes. The guaranteed enzymatic activities are also supported by several additional activities, for example pectinase, mannanase and cellulase.

AveMix® XG 10 enables more flexible feed formulation

The optimized formulation of AveMix® XG 10 enables it to be flexible and to work on both soluble and insoluble fibers of different feed formulations. This is because arabinoxylans  and glucans are common components of all plant-based feed ingredients, not just cereals. As such, AveMix® XG 10 allows a higher inclusion of fiber materials, including cheaper alternative by-products, which enables flexible feed reformulation. Due to our extensive database, we can also advice on how AveMix® XG 10 can be most effectively applied to your feed formulation in order to get the best economic return.

In conclusion, AveMix® XG 10 is an EU approved feed additive that improves nutrient digestion and absorption in the animal by overcoming issues associated with NSP fibers. This results in cost-effective feed utilization and improved animal performance, with the option of improving feed formulation economy.
