1. Mannanase, since it degrades β-mannan of feed ingredients, can eliminate the effects of anti-nutritional factors of mannan to increase nutrient digestibility and improve animal growth.

2. Under stress condition, β-mannanase can greatly improve the growth performance of livestock and poultry.

3. Adsorb mycotoxin. Studies show that mannan-oligosaccharide, degraded from mannan, can eliminate harmful effects of mycotoxin on livestock and poultry by physical adsorption or direct integration.
