Improved feed efficiency with NSP enzymes

mon, 25 feb 2013
An important point within livestock farming is the lowering of feed costs. To that end the addition of enzymes is a tried and tested means. Endogenous digestive enzymes are responsible for the breakdown of feed in the gastrointestinal tract: amylase (for the digestion of starch), protease (protein) and lipase (fat). Grains and plant-derived feedstocks, however, contain elements that are not digested by endogenous enzymes: NSPs (non-starch polysaccharides) such as xylans, glucans, pectin, cellulose, hemicellulose).

NSP enzymes split these long sugar chains into smaller bits. Highly digestible nutrients embedded in clusters of cell wall material and thus inaccessible to digestive enzymes can now be digested. Moreover, the content of the intestine becomes thinner and improves the digestion enabling the feed pulp to mix well with the enzymes and bile salts. Finally, the smaller bits that are created by NSP enzymes are fermented into volatile fatty acids which also contribute to the animal’s energy supply.

Adding NSP enzymes to pig and poultry feed will improve the digestibility and increase the nutritional value of the feedstocks. When the higher nutritional value is arrested, the raw material price of the compound feeds will decrease and, as a result, so will the cost of feed. Initially NSP enzymes were mainly added to the feed of young animals, but our impression is that these enzymes are also increasingly being used in porker feeds, for example.

Nuscience will be pleased to inform you about the possibilities offered by the various NSP enzymes in pig and poultry feed and to advise you when choosing a specific enzyme that best suits your requirements.
