Functions
1. Degrade mannan in feedstuff, like soybean, palm kernel, copra, etc.
2. Eliminate anti-nutritional factors in feed and promote nutrient substance digestion and absorption. Improve the value of feed and lower the cost.
3. Improve the digestibility of the nutrients, release nutrients in the cell, and degrade the complex of mannan and protein and polysaccharide to enhance the absorption of nutrient.
4. Enhance animal’s health. Degrade mannan to mannose, which can significantly promote the proliferation of profitable bacteria represented by bifidobacterium in animal intestine, increase animal’s immunity and reduce the mortality rate of animal.
Definition of content
One unit of mannanase activity is defined as the amount of enzyme which liberates 1 micromole of reducing sugar per minute from 3 mg/mL of mannan at pH 5.5 and 37℃.
Dosage
Recommended dosage is 100-150g/t with 10000U/g in complete feed.
