At a certain temperature (40±0.2℃) and corresponding pH conditions (acid protease pH3.0, neutral protease pH7.5, Alkaline protease pH10.5, Ceratinase pH10.5), the amount of enzyme reguired to hydrolyzecasein to 1 ug of phenolic amino acids (represented by the tyrosine equivalent) within 1 min is defined as one enzyme activity unit (U).

It can promote the digestion and absorption of feed protein, improve feed digestibility.

It can promote the degradation of anti-nutritional factors in feed, and effectively reduce animal diarrhea

It can improve the immunity of animals

Based on the specification of 50,000 U/g, 30-60 g of acid protease or 30-50 g of neutral protease is added to each ton of compound feed.

Based on the specification of 200,000 U/g, 10-20 g of alkaline protease or 15-25 g of ceratinase is added to each ton of compound feed.
