Functions of in Protease

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 in Protease

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 of in Protease

Recommended dosage is 50-100g/t with 50000U/g in complete feed.
