Description
Protease catalyzes peptide bond and hydrolyzes protein into peptone, hydrazone, polypeptide and amino acid. As a kind of alkaline serine protease, keratinase not only has the function of normal alkaline protease, but also can break down disulfide bond and disintegrate keratin.

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 10.5 under the conditions of the test.
Functions
1. Supplement the deficiency of endogenous protease for animal.
2. Increase the digestibility of protein and amino acid in poultry and swine feed ingredients.
3. Degrade the trysin inhibitor and lectin, this is what endogenous protease can’t do.
4. Optimized the use of lower digestibility feed ingredient e.g corn, sorghum, feather meal,soybean meal and blood plasma powder.
5. Creat a better environment for animal and decrease pollution from nitrogen for human.
Dosage
Recommended dosage is 50-100g/t with 50000 U/g in complete feed.
