Leiber YeaFi^® products – a successful combination with a long tradition. The recipe for success lies in the product design: Leiber YeaFi^® consists of a unique combination of brewers’ yeast with functional fibre carriers and is produced in an equally unique way: the brewers’ yeast is sprayed onto the fibre carrier in liquid form and dried without contact. This gentle process protects the product from demixing during handling and transport, removes the hygroscopic properties of the brewers’ yeast and creates an optimised physical structure for an otherwise pulverous product.

Advantages of Leiber YeaFi^® in poultry feeds:

• Easy to dose
• Dry and storable for a long time
• Highly flowable
• Fibre supplements
• Promotes gut health
• Provides fibre

Leiber Brewers’ Yeast^® is rich in valuable bioavailable active ingredients and nutrients. It’s produced in the breweries in compliance with strict food industry guidelines. This makes it a real brewers’ yeast, because it contains the polyphenols from the hops, which are added during the brewing process. These hop polyphenols complement the well-known beneficial nutritional properties of brewers’ yeast by providing additional antioxidant and bacteriostatic effects.

Advantages of Leiber Brewers’ Yeast^® in poultry feed:

• Nutrients and active ingredients
• Binds pathogens
• Provides B vitamins
• Promotes gut health

Biolex^® MB40 consists of cell walls of brewers’ yeast (100% Saccharomyces cerevisiae), obtained by centrifugation after biotechnological disruption of yeast cells. During this process, mannan oligosaccharides (MOS) and beta-glucans accumulate and specifically active segments of the cell wall are released. Mannan oligosaccharides (MOS) have specific surface receptors that can bind mannose-sensitive Salmonella and E. coli and are also carbohydrates that are fermented by the intestinal flora. This creates a hostile environment for pathogenic germs, so that they are also inhibited in a natural way. The beta-glucans in the yeast cell walls have an immune-stimulating effect and promote the birds’ immune system.

Advantages of Biolex^® MB40 in poultry feeds:

• Prebiotic effect
• Promotes gut health
• Binds pathogenic germs in the digestive tract
• Strengthens the innate immune system

With Leiber^® Beta-S, your poultry’s immune system can be activated particularly effectively. The reason lies in the special product concept developed by Leiber: Leiber^® Beta-S consists of highly purified β-1,3-1,6-glucan molecules from the cell wall of brewers’ yeast (100% Saccharomyces cerevisiae). A particularly gentle process detaches the beta-glucans from the cell wall complex of brewers’ yeast. In this way, the native structure of the molecules and thus their biological activity is retained much better than in conventional methods. The animals’ immune system reacts to the structure of the beta-glucan molecules and is put into an active state, but without being over-stimulated.

Advantages of Leiber^® Beta-S in poultry feed:

• Improves non-specific immune response
• Low dose required
• No over-reaction of the immune system

1. Uptake of ß-glucans from the gut lumen via M cells and phagocytosis by macrophages (or also via dendritic cells)
2. Activation of macrophages increases phagocytosis and the release of reactive oxygen and nitrogen radicals (oxidative burst), antimicrobial peptides and lysozyme increased combat of pathogens
3. Release of cytokines and chemokines recruits more immune cells. Macrophages present antigenic structures to T and B cells, causing B cells to subsequently produce antibodies
4. Activated macrophages migrate to organs of the immune system where they break down the ß-glucans into smaller fragments
5. In the organs of the immune system (bone marrow, spleen and lymph nodes), these ß-glucan fragments and cytokines are released, activating other immune cells such as granulocytes and NK and T cells
