The use of fibre-degrading enzymes continues to grow worldwide, with producers seeking real feeding cost savings. Of the many different types of fibre-degrading enzymes commercially available, xylanases are known to have the most supporting evidence and be the most effective.

AB Vista’s beta 1-4 endo-xylanase product, Econase®​ XT, is inherently thermostable and developed for use in monogastric feeds.

Xylanases are required in monogastric diets because:

  • High levels of dietary fibre depress nutrient digestibility and performance
  • The endogenous enzymes of monogastrics cannot digest dietary fibre
  • Exogenous xylanase stimulates nutrient digestibility and enhances performance

Enzymes are sensitive to heat and pressure and can be rendered inactive by feed processing.  Econase®​ XT is unique in that it is the only fibre degrading enzyme that is fully intrinsically thermostable as a liquid powder.  In this regard, it is the enzyme molecule itself that is stable to pelleting temperatures, rather than stabilising techniques such as coating associated with other products.

Econase®​ XT can withstand pelleting temperatures as high as 95o​C (203o​F), maintaining enzyme activity post-pelleting.  The stability has been demonstrated in a wide range of pelleting tests within institutes and commercial feed mills.

Econase®​ XT is the first and only liquid NSP enzyme sufficiently thermostable to be added to feed prior to pelleting.  Applying liquid Econase®​ XT to the batch mixer results in improved enzyme homogeneity throughout the feed, and can offer the user a potential economic advantage in terms of reduced power output when pelleting.  Econase®​ XT Mixer Liquid Application (MLA) technology offers users further flexibility in application and ease of use.

Easily detected and measured with AB Vista’s ELISA rapid in-feed assay kit, Econase®​ XT ensures greater ease of quality control in feeds.

Increased sensitivity central to successful soybean processing

The production of soybean meal requires several processes including the application of a range of grinding, pressures and temperatures to extract the required oils, remove anti-nutrients (e.g. trypsin inhibitors) and increase digestibility. This can impact...
