Reasonable application of enzyme preparation feed additive

Enzymes are active substances produced by living organisms and are catalysts for various biochemical reactions in the body. The digestion, absorption and utilization of various nutrients must rely on the action of enzymes. Enzymes have the characteristics of specificity, high efficiency and specificity. There are thousands of enzymes that have been discovered, more than 300 kinds of enzymes have been artificially produced, and more than 20 kinds of enzymes are used in the feed industry . Active enzyme products are produced by bioengineering methods, called enzyme preparations. Enzyme preparations are a type of feed additive that has been widely used in feed in recent years, and most of the enzyme preparations used in feed additives are digestive enzymes. Enzyme preparation is an environmentally friendly green feed additive because it can effectively improve the utilization rate of feed, save feed raw material resources, and has no side effects, and there is no adverse effects such as drug residues and drug resistance of drug additives.

Main types of enzyme preparation feed additives

amylase. Amylases mainly include alpha - amylase and saccharification. Alpha - amylase can decompose starch macromolecules into easily absorbed medium and low molecular weight substances. Saccharification enzyme can further hydrolyze the medium and low molecular substances decomposed by α - amylase into glucose, which can be absorbed and utilized by animals.

protease. Protease is a hydrolase that degrades protein peptide chains, mainly including pepsin, trypsin, papain, etc.

Cellulase. Cellulase can destroy the crystalline structure of cellulose, hydrolyze cellulose macromolecules into oligosaccharide fragments, and decompose oligosaccharide substances into glucose.

Beta-glucanase. β - glucan is widely present in a variety of plant materials and has a high viscosity. It is an important antioxidant factor that affects the transmission and absorption of nutrient molecules. Beta - glucanase can hydrolyze macromolecules such as glucan, reduce the viscosity of substances in the digestive tract, and promote the absorption of nutrients. β - glucanase is an important and widely used enzyme in enzyme preparation feed additives.

pectinase. Pectin is an anti-nutritional factor in plant raw materials, which affects the utilization rate of feed. Pectinase can effectively destroy pectin and promote the digestion and absorption of nutrients. Pectinase is also a commonly used feed enzyme preparation.

Phytase. Most of the phosphorus in grains is in the form of phytate phosphorus, and animals themselves do not secrete phytase, so the utilization rate of this part of phosphorus in grains is low, and by adding phytase secreted by microorganisms to the feed, This part of phosphorus can be decomposed and released, thereby reducing the amount of inorganic phosphorus added in the feed, reducing the cost of the feed, and reducing the excretion of phosphorus in animal manure and reducing environmental pollution. It is a green feed additive with many applications and the best prospects.

complex enzyme. Compound enzyme is a product made by mixing two or more biologically active enzymes. Compound enzymes are formulated according to the characteristics of different animals and different growth stages, and have good effects, and are currently the most commonly usedfeed additives.
