Poultry

Your animals – hens in egg production, parent animals in breeding companies or broilers for fattening – must have the best possible health status. Leiber offers you a broad product range that supports you in promoting the health of your animals. Leiber Brewers’ Yeast products can be used in many different ways in poultry farming – for example in mineral feeds, in complete feeds or as an additive to special products in broiler and laying hen feeding. Leiber products are designed to enhance animal health at every stage and are produced in a natural and sustainable way.

Product range

Leiber Brewers’ Yeast – the best for poultry feeds

Leiber YeaFi®

Easy handling. Clever combination.

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

We recommend the following for use in poultry feeding:

Leiber YeaFi® BT: inactivated brewers’ yeast bound to spent grains – successful and traditional.

Leiber YeaFi® BM: inactivated brewers’ yeast bound to malt germs – with a coarse structure and rich in lignin.

In addition, Leiber YeaFi® products are also available with other fibre carriers, e.g. wheat bran or spent grains with beet pulp.

All of these are also available as finely ground variants.

Leiber Brewers’ Yeast®

Real brewers’ yeast, tried and tested.

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

Prebiotic – promotes 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

Leiber® Beta-S

Glucan for health

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

Presentation of the main mechanisms of action of Leiber® Beta-S

  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

Functions
For healthy performance.

Gut health

Gut health

Good health begins in the gut

The ingredients and physiological properties of Leiber Brewers’ Yeast products support animals’ gut health with important nutrients for their microbiome.

 

Dietary fibre – an often under-estimated proportion of the ration – provides an important basis for synthesising short-chain fatty acids, which supply the gut’s immune system with energy. After all, the digestive system is largely responsible for the breakdown and absorption of nutrients. At the same time, the intestine has the largest proportion of immune cells in the body. A healthy gut protects animals from diseases and negative environmental influences, while at the same time being the engine for enhanced performance.

 

Advantages of Leiber Brewers’ Yeast products for poultry:

  • Dietary fibre promotes gut health

  • Strengthen the immune system through short-chain fatty acids

  • Prebiotic effect of inactivated brewers’ yeast

  • Promote health and performance

Digestion

Digestion

Efficient digestion thanks to effective nutrients

The short digestive tract of poultry and its small capacity place high demands on poultry feed. Leiber Brewers’ Yeast products are readily digestible, rich in crude fibre and not very bulky. That’s why they are the ideal feed for poultry. They promote gut health, which is critical to good digestion and effective nutrient absorption. In this way, Leiber Brewers’ Yeast products increase and maintain the health and performance of your animals.

 

Advantages of Leiber Brewers’ Yeast products for poultry:

  • Prebiotic mechanisms of action
  • Bioavailable nutrients from yeast
  • Improve digestive capacity
  • Increase nutrient absorption

Prebiotic effect

Prebiotic effect

Prebiotic. Promotes health.

Prebiotic mechanisms of action promote well-being, boost health and thus promote the performance of poultry in all phases. Leiber Brewers’ Yeast products with inactivated yeast contain prebiotic ingredients like mannan oligosaccharides (MOS) which serve as a fermentation substrate for the microbiome. A healthy and supported microbiome supports gut health, ensuring that digestive and absorption processes run efficiently. The natural components of the beta-glucans in yeast cell walls also have an immune-stimulating effect.

 

Advantages of Leiber Brewers’ Yeast products for poultry:

  • Promote gut health
  • Eubiosis in the gut
  • Displace pathogenic germs through optimal pH value in the gut
  • Strengthen the gut-associated lymphoid tissue (GALT)

Immune system

Immune system

Small molecule – big protection

The beta-glucans in the yeast cell walls activate the immune system, thus promoting the natural defences of poultry against pathogenic germs. Contamination and pollution occur in every hen house, in feeds and, of course, in free-range farming. Since infections can lead to performance dips or even high losses, actively protecting the immune system with Leiber® Beta-S makes economic sense.

 

Advantages of Leiber Brewers’ Yeast products for poultry:

  • Activate the innate immune system
  • Improve specific and non-specific responses of the body
  • Promote the immune competence of young animals
  • Increase resistance to negative environmental influences

Performance

Performance

Good performance makes good economic sense.

Performance parameters like growth, feed conversion or egg quality are of great importance for the economic success of a company. A healthy gut and digestion form the essential basis for good performance. If nutrients from the diet are well absorbed, they can be incorporated directly into the body dimensions and lead to a high slaughter weight. Feed conversion is reduced because the digestive system – ‘the engine’ – works efficiently and reduces unnecessary nutrient excretion.

 

Advantages of Leiber Brewers’ Yeast products for poultry:

  • Increased performance thanks to better health
  • Gut health improves nutrient absorption
  • Increased slaughter weight in fattening broilers
  • Better feed conversion in fattening
