Animal feed enzyme
is a kind of feed additive, which can improve the digestion, utilization or metabolic efficiency of animal feed and add enzymes into feed.
Animal feed enzymes are enzymes added to feed to improve digestion, utilization or metabolic efficiency of animal feed.
At present, enzymes that can be added to feed include amylase, alpha-galactosidase, cellulase, beta-glucanase, glucose oxidase, lipase, maltase, mannanase, pectinase, phytase, protease, keratinase, xylanase, etc. Because of the complexity of feed raw material structure, compound enzyme preparation is more used in feed industry production. Compound enzymes are products containing two or more single enzymes.
The main applications:
Eliminating anti-nutritional factors in feed
Xylan, beta-glucan, cellulose and other non-starch polysaccharides are difficult to digest and absorb by animals (especially monogastric animals). They are the components of plant cell wall, and can increase the viscosity of digestive tract chyme, resulting in lower nutrient digestibility and feeding effect of diets, which limits the application of cereals in feed. Non-starch polysaccharide enzymes such as xylanase and beta-glucanase can decompose non-starch polysaccharides and eliminate their anti-nutritional effects. Phytase can eliminate the anti-nutritional effect of phytic acid and improve the utilization of phosphorus.
Deficiency of endogenous enzymes
The phenomenon of insufficient endogenous enzymes such as protease and amylase secreted by animals is very obvious in young animals and sub-healthy animals such as stress and disease: dyspepsia and a series of production performance decline caused by it, such as diarrhea in weaned piglets. Targeted addition of exogenous enzymes will effectively solve the above phenomena.
Reducing Environmental Pollution
Adding animal feed enzymes
can reduce the excrement discharge of livestock and poultry. Enzyme preparation can improve the utilization rate of nitrogen and phosphorus in feed, decrease the content of nitrogen and phosphorus in feces and urine. The most direct way is to reduce the concentration of harmful gases in livestock houses, reduce the incidence of respiratory diseases in livestock and poultry and other diseases caused by adverse environment. Enzymes are added to feed in order to improve digestion, utilization or metabolic efficiency of animal feed.
