Farm animals face numerous stress factors, including pathogen pressures, high stocking densities, intensive growth, extended production periods, and heat stress. Protecting animals against stress and improving their performance in challenging conditions is crucial. Dietary antibiotics have been used for a long time to prevent disease and enhance growth performance in livestock. However, concern about the contribution of these substances to the increase in antibiotic-resistant human pathogens has led to strict regulations for their use. As a result, research effort has been dedicated to finding alternatives. One of these possible alternatives is the use of yeast products.

Immune Cells

In newborns, the immune system is considered relatively immature, and it has to develop in a balanced way in interaction with the challenges from the environment during the first period of life. With increasing age, a decline in the functioning of the immune system is observed in all animal species. Also, external factors such as nutrition, chemicals, immunosuppressive viruses and longer-term exposure to stress may contribute to the impairment of the immune system.

It is essential to have an effective solution to protect animals against stressors and challenges while modulating the immune system and improving performance.
Biomannan Bag

Biomannan® is an advanced biotechnology solution derived from Saccharomyces cerevisiae yeast cell wall, rich in highly purified Mannan-oligosaccharides and β1,3-β1,6-D-Glucan.

Why Biomannan®?

Mannan-oligosaccharides help diminish pathogen colonization in the animal's intestinal tract by adsorbing gram-negative pathogens. Beta-glucans stimulate the immune system by being in contact with the immune system macrophages and trigger a cascade of immune events in much the same manner as an actual pathogen would, thus turning the immune system into an arsenal of defence. 

Biofeed's Beta-glucan
Biofeed's Mannan-oligosaccharides

Biomannan®'s positive effects have been demonstrated in multiple species, including poultry, swine, ruminants, aquaculture, equine and pets. By reducing the translocation of bacterial products, reinforcing the epithelial barrier, and modulating cellular and humoral immunity, Biomannan® helps animals be more resilient, resulting in an excellent performance. The addition of Biomannan® to animal diets assists in restoring gastrointestinal balance, preserving gut integrity, and modulating immunity. Biomannan® can help mitigate the detrimental effects of stress and improve feed efficiency, animal performance, and food safety.
