  In China, feed enzymes are mainly sold in the form of phytase and compound enzymes rather than sold individually to feed enterprises or breeding enterprises, excluding phytase. Feed enzymes are a new-type feed additives produced through microorganism fermentation. They play an important role in the current farming system. Phytase and NSP enzyme are the most widely used varieties in China’s feed industry. Feed enzymes can increase animals' digestibility of nutrients, bringing greater efficiency in the production of animal products such as meat and eggs. At the same time, they play an important role in minimizing the impact of increasing animal production on environment. 
  Phytase (myo-inositol hexakisphosphate phosphohydrolase) is a type of phosphatase enzyme that catalyzes the hydrolysis of phytic acid (myo-inositol hexakisphosphate)—an indigestible organic form of phosphorus that is found in grains and oil seeds, and releases any usable form of inorganic phosphorus.
  NSPs enzyme (non-starch polysaccharides enzyme) is the main kind of feed enzyme which includes xylanase, β-glucanase, mannanase, pectinase, cellulase, etc. It couldn't be secreted in livestock's body and need to be added in livestock feed to decompose anti-nutritional factors and promote the absorption of nutrients. 
  Protease is a kind of endogenous enzyme that could catalyze and decompose peptide bonds in proteins. It could eliminate the effects of anti-nutritional factors on protein feedstuff.
  Amylase is a kind of endogenous enzyme that catalyzes the breakdown of starch into sugars. It could help livestock, especially young animals that secrete insufficient amylase, to improve nutrient digestion and absorption.
  Feed enzyme is mainly obtained by microorganisms fermentation in China. Most of enterprises use genetic engineering strains as enzyme resource. The most widely used enzyme resource include: aspergillus niger, aspergillus oryzae, bacillus subtitles, trichoderma longibrachiatum, penicillium notatum, etc. The general production process flow:
  1. Screening microbial strains (fungi or bacteria) with strong enzyme secretory ability;
  2. Culturing strain;
  3. Preparation of fermenting raw materials;
  4. Sterilization;
  5. Vaccination;
  6. Fermentation;
  7. Post-processing;
  8. Refining enzyme resource;
  9. Compounding;
  10. Product.
