The Function of Enzyme Preparation Feed Additives
1. Enzyme preparation feed additives
As feed additives, enzyme preparations mainly include digestive enzymes and phytase. Enzyme preparations can effectively improve feed utilization, save feed resources, have no side effects, no drug residues of drug additives, and adverse effects such as drug resistance, thus enzyme preparations are environmentally friendly and green feed additives.
2. The role of enzyme preparation feed additives
Enzyme preparation feed additives directly decompose nutrients and improve feed utilization. A variety of active enzymes can effectively decompose and digest some macromolecular polymers in feed into nutrients that can be easily absorbed by animals or into small fragments of nutrients for further digestion by other digestive enzymes. Some macromolecular substances are difficult for animals to decompose and absorb, so the addition of enzyme preparations can promote the decomposition and digestion of nutrients in the feed, thereby improving feed utilization.
Enzymatic feed additives eliminate anti-nutritional factors and improve digestion. Some non-starch polysaccharides, pectins, and cellulose polymers often exist in plant feed materials. These substances increase the content and viscosity of the animal’s digestive tract and affect the effective nutrients of the animal. The digestion and absorption of the enzyme preparations, especially β-glucanase, pectinase, and cellulase, can decompose these substances into small molecular substances, thereby reducing the viscosity of substances in the digestive tract and effectively eliminating the adverse effects of the anti-nutritional factors, and improving the digestive performance of animals. Enzyme preparation feed additives activate the secretion of endogenous enzymes and increase the concentration of digestive enzymes, and increase the concentration of digestive enzymes. The use of enzyme preparations provides more substrates that can be decomposed by a variety of enzymes, thereby stimulating more secretion of a variety of digestive enzymes in animals, increasing the effective content of digestive enzymes, accelerating the digestion and absorption of nutrients, thereby improving feed utilization rate and accelerating the metabolism of animals, and promoting animal growth.
