Mannanase is a non-starch polysaccharide enzyme that primarily degrades β-mannan in feed,
and is widely used in livestock, poultry, and aquaculture feeds. Its core functions and mechanisms are as follows:
1) Degradation of anti-nutritional factors
Raw materials such as soybean meal, rapeseed meal, cottonseed meal, coconut meal, and guar gum are rich in β-mannan,
a potent anti-nutritional factor. It increases intestinal chyme viscosity, slows nutrient absorption,
hinders the interaction between digestive enzymes and nutrients, reduces utilization efficiency of protein, starch, and fat, and affects intestinal motility,
leading to diarrhea and digestive disorders. Mannanase breaks down these substances into small oligosaccharides and monosaccharides,
thereby eliminating the negative effects caused by high viscosity.
2) Enhancing feed nutrient utilization
By breaking down polysaccharides, mannase releases absorbable sugars,
improving energy utilization and reducing feed conversion ratio (FCR) or feed-to-egg ratio.
It also releases proteins, amino acids, and minerals previously bound by polysaccharides,
enhancing the absorption rates of protein, calcium, phosphorus, and other nutrients.
Under equivalent production performance, this allows for a reduction in feed formulation costs related to energy and protein content.
3) Improving intestinal health
Optimizing gut microbiota: The mannan oligosaccharides produced during degradation serve as carbon sources for probiotics
(such as lactic acid bacteria and bifidobacteria), inhibiting the growth of harmful bacteria.
Maintaining intestinal barrier function: Reducing intestinal burden, minimizing intestinal wall damage,
and lowering the incidence of enteritis and diarrhea.
Reducing harmful intestinal metabolites and enhancing overall animal resistance.
4) Alleviating stress and improving production performance
Mitigating growth inhibition caused by anti-nutritional factors in raw materials, thus accelerating growth rates in livestock and poultry.
In laying hens, it helps stabilize egg production and improves eggshell quality.
In aquatic animals, it reduces intestinal problems, increasing survival rates and weight gain.
It also alleviates feeding depression caused by stressors such as diet changes, environmental shifts, and transportation.
