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.

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 nutritional strategy to help animals cope with stressors and challenges while supporting normal immune function and overall performance.

Biomannan® provides a concentrated source of naturally occurring yeast cell wall components, including mannan-oligosaccharides and β-1,3/β-1,6-D-glucans. These structural components are widely used in animal nutrition and are suitable for incorporation into livestock feeding programs as part of a broader gut-health and nutritional strategy.


Biomannan® has demonstrated positive effects in multiple species, including poultry, swine, ruminants and aquaculture. Biomannan® helps support animal resilience and overall performance. The addition of Biomannan® to animal diets can help support gastrointestinal balance and maintain gut function. Biomannan® may also help animals better cope with the effects of stress while supporting feed efficiency and overall animal performance.
