EnzymesEnzymes are naturally occurring proteins that catalyse biological chemical reactions. Enzymes are often added to improve the nutritive value of animal feed and work by digesting the complex feed molecules such as those found in cereals into smaller constituents such as glucose or amino acids, which are essential for life. Feed enzymes can also help reduce environmental impact through the better utilisation of feed nutrients such as phosphorus and nitrogen. Enzymes commonly used in the feed industry include phytase, β-glucanase and xylanase.
Phosphate Liberating EnzymesPhytase works by attacking phytate in cereal and oilseeds and freeing the bound phosphate within the grain. This can in turn lead to the release of phytate-bound minerals such as calcium and magnesium. The unbound phosphorus is essential for good bone growth while undigested phosphorus is a potential environmental pollutant. The phytase range - FinaseŽ - are offered in different phytase concentrations.
Non Starch Polysaccharide Degrading EnzymesXylanase and β-glucanase work by breaking down cereal and legume non starch polysaccharides such as arabinoxylans and mixed-linked β-glucans, to open up cell walls and release the enclosed nutrients, resulting in a concomitant decrease of viscosity. This allows the animal to obtain more nutritive value from the feed. AB Vista™ offers an EconaseŽ range of products for wheat, barley and other grain based diets, which are available as micro-granules or liquids.
