Seeing is believingVISUALISATION OF THE ANTI-CAGING EFFECT OF RONOZYMEr WX

摘要

Cereals contain varying forms of carbohydrates which play an important role in animal nutrition. Non-structural carbohydrates such as simple sugars and starch are major nutritional components in pig and poultry diets, as they are the predominant sources of energy. Starch, as well as protein, is located in the endosperm of the grain, and is stored in starch granules within a protein matrix which is encapsulated by the plant cell wall. The cell wall consists primarily of structural carbohydrates, morecommonly referred to as non-starch polysaccharides (NSP). NSP's include the arabinoxylans which are present in both soluble and insoluble forms depending on molecular chain length and amount of branching on that chain. Wheat contains approximately 114g/Kg NSP's, 71 % of which are arabinoxylans (AX). 22% of the AX in wheat are soluble in water, the remaining 78% being insoluble. AX are largely undigested by monogastric animals due to a lack of relevant endogenous enzymes in their digestive tracts, thus,the cell walls can be described as the 'cage effect'. To successfully breakdown arabinoxylans, pigs and poultry require an exogenous xylanase enzyme. RONOZYMEr WX is a mono-component xylanase active against both soluble and insoluble AX, and is capable of inhibiting the cage effect, releasing encapsulated starch and protein.
