Acid protease
Description
Protease catalyzes peptide bond and hydrolyzes protein into peptone, hydrazone, polypeptide and amino acid. Activity center of acid protease includes aspartic acid. Priority cut open peptide bond of aromatics or hydrophobic amino acids and produce small peptide and amino acid.

Functions
1. Supplement the deficiency of endogenous protease for animal.
2. Increase protein digestibility in animal feed and reduce the dosage of protein in feed formula.
3. Decrease the difference of feedstuff from different area and stabilize production performance.
4. Protect the environment by decreasing pollution from nitrogen.
Definition of activity
One unit (U) of protease activity is defined as the amount of enzyme which liberates 1 μg tyrosine per minute from substrate casein at 40℃ and pH 3.0 under the conditions of the test.
Dosage
Recommended dosage is 50-100g/t with 50000U/g in complete feed.
