Two fractions, two jobs

Yeast cell wall products vary widely, because the term covers everything from a whole spent yeast to a purified cell wall fraction. What determines the biological effect is the quantity of mannan-oligosaccharides and beta-glucans actually present. BgMOS is specified on those fractions rather than on total yeast content.

Mannan-oligosaccharides and beta-glucans are both derived from the yeast cell wall, but they do different things. MOS presents mannose residues that type-1 fimbriated bacteria bind in preference to the intestinal mucosa, so the bacteria pass through instead of colonizing. Beta-glucans interact with receptors on immune cells and modulate the innate immune response. A product specified only as yeast cell wall does not tell you how much of either you are buying.

How it works

0 Pathogen agglutination.

Mannose residues on the cell wall bind type-1 fimbriae of Gram-negative bacteria, agglutinating them in the lumen and reducing their attachment to the intestinal mucosa.

0 Microbiome balance.

By removing type-1 fimbriated bacteria from the mucosal surface and altering competition in the lumen, the product shifts microbiota composition in favor of commensals. Yeast cell wall mannan-oligosaccharide is only partly fermentable and acts principally through adhesion rather than through selective fermentation.

0 Mucosal support.

Increased mucus production improves conditions for the preservation of intestinal tissue integrity.

0 Immune modulation.

Beta-glucans are recognized by innate immune receptors and modulate the innate immune response, with indirect downstream effects on adaptive immunity.

Technical notes

Specification

The product is specified on declared minimum quantities of mannan-oligosaccharides and beta-glucans rather than on total yeast content, which is what makes results repeatable across batches. The declared figures should be added to the specification table before publication.

Thermostability.

High thermostability allows inclusion ahead of pelleting without a protective coating.

Program fit.

Prebiotics act on microbiome composition and pathogen adhesion. They are complementary to, not a substitute for, acidification, phytogenics and enzyme strategies.

What the trials show

Post-weaning piglet performance versus colistin:

Evidenced in a piglet trial evaluating BgMOS against colistin in weaned pigs. Piglets receiving BgMOS achieved superior growth performance compared with the colistin-treated group, demonstrating that the yeast-cell-wall-derived MOS product effectively supported post-weaning performance under conditions traditionally managed with antibiotic intervention.

Growth performance and antibiotic-replacement potential in broilers:

Evidenced in 1 broiler trial comparing BgMOS with an antibiotic growth promoter. Birds receiving BgMOS achieved performance results comparable to those obtained with antibiotics, indicating that BgMOS can support growth and production efficiency while contributing to antibiotic-reduction strategies.

Immune status and growth performance in shrimp:

Evidenced in a shrimp trial evaluating BgMOS supplementation. The inclusion of BgMOS improved both growth performance and immune-related parameters, demonstrating benefits extending beyond productivity and supporting overall animal robustness under commercial aquaculture conditions.

Synergistic immune and performance response in shrimp when combined with phytogenics:

Evidenced in 1 shrimp trial evaluating the combination of BgMOS plus Activo Liquid. The combined program enhanced immune-related parameters and growth performance, suggesting that the simultaneous use of mannan-rich yeast fractions and phytogenic compounds can provide complementary support for shrimp health and productivity.

Gut Health

Where it fits

BgMOS is used continuously in young animal and breeder diets, where microbiome establishment and immune development are the objective, and in pet food where the same rationale applies. Inclusion rates are highest in piglet diets and lowest in fattening pigs and poultry. It combines readily with organic acid and phytogenic programs.
