When phytase is used in excess in the formula, how should the addition of calcium hydrogen phosphate be adjusted? A: When phytase is used in…

Q: How to use enzyme preparations in expanded aquatic feed? A: Enzyme preparations are biologically active substances that are very sensitive to high temperatures, so…

Q:For feed Enzyme, is the higher the enzyme activity, the better? A：Not necessarily, it depends on the type of enzyme. Endogenous digestive enzymes such as amylase and protease have an upper limit. When excessive…

Select the phytase variety with the best phosphorus release rate; try to use feed ingredients with rich phosphorus content; use phytase in excess dose (6-12…

Q: What are the contents of enzymatic properties?  Which characteristics are reflected respectively? A: Enzyme is a kind of protein, which is sensitive to temperature, PH and endogenous protease.The action site of enzyme in our feed is in the stomach and intestinal tract, so the enzyme needs to be resistant to the high temperature of feed processing in order to play an effective roleGranules, resistant to gastric acid, resistant to endogenous proteases. Usually, the key evaluation indicators in the experiment include heat resistance, acid resistance, PH adaptability, temperature adaptability, endogenous digestive enzyme resistance and so on.
