What is the role of xylanase in feed?

View: 7 Author: Site Editor Publish Time: 2022-10-19 Origin: site

At present, corn is used as the main energy feed in the feed industry. The supply of raw materials is becoming increasingly scarce, and the price of corn is rising, which seriously affects the development of the pig industry. It is one of the important measures to alleviate the shortage of corn to fully develop and utilize the wheat, grain, bran, etc., which are rich in resources in our country to replace corn. However, the cell walls of wheat, cereals, bran and other grains contain anti-nutritional factors such as arabinoxylan, non-starch polysaccharide (NSP), which affects the digestibility of nutrients in monogastric animals and affects the absorption of nutrients in poultry. The main one is arabinoxylan. Arabinoxylan is a polysaccharide in rice bran (hemicellulose B) edible fiber. Corresponding xylanase  needs to be added to the feed to degrade arabinoxylan and improve feed absorption. utilization.

What is the mechanism of action of xylanase supplementation in feed?

The application of xylanase in the feed industry can decompose the anti-nutritional factor non-starch polysaccharide (NSPS) in the grain seeds of the feed into xylo-oligosaccharides with a smaller degree of polymerization, decompose the raw material cell wall and β-glucan, eliminate the Or reduce the anti-nutritional effect of non-starch polysaccharides in the animal stomach due to the high viscosity, promote the release of effective substances, and at the same time it can destroy the structure of plant cell walls, improve the activity of endogenous digestive enzymes, and improve the utilization of feed nutrients. 

What is the role of xylanase supplement  in feed?

1. Generate a large amount of functional oligosaccharides (xylobiose, xylotriose, etc.) to improve the intestinal microflora, which is beneficial to animal health. 

2. Reduce the quality fluctuation of feed products caused by the quality variation of feed raw materials, stabilize product quality, and reduce complaints.  

3. Expand the scope of use of feed raw materials, increase the amount of unconventional feed such as bran, secondary flour, rice bran, etc. in the feed, and reduce the cost of feed formula.  

4. Increase the absorption and utilization of nutrients, reduce the discharge of feces, protect the environment, and at the same time reduce the stimulation of harmful gases generated by the decomposition of fecal organic matter to livestock and poultry, and reduce the occurrence of respiratory diseases. 

Development prospects of xylanase

China has joined the WTO, and foreign low-priced wheat and barley products are about to flood into the Chinese market, which will further stimulate the market demand for xylanase. At the same time, with the start and implementation of my country's feed safety project, antibiotics and other residues will be generated, and the use of feed additives that are resistant to antibiotics and pollute the environment will be restricted and will be gradually banned or eliminated. Growth-promoting additives with medicinal properties that do not pollute the environment will be vigorously promoted and used.
