The biological value of a feed mixture should not be measured by the standards "energy, minerals and vitamins" alone. Of outstanding significance for animal performance is the bioavailability of the nutrients and active ingredients, which can be crucially increased by the use of the natural product brewers’ yeast (Saccharomyces cerevisiae).
Due to the dietary and prebiotic modes of action of Leiber® brewers’ yeast and the fact that it contains many valuable ingredients, each feed mixture achieves a decisive increase in value.
Brewers’ yeast, which is one of the most valuable natural products, must therefore be seen first and foremost as an active ingredient carrier, and only secondly as a nutrient carrier. The effect of the important ingredients, such as enzymes, B-vitamins, amino acids and minerals is based on the interaction of all ingredients in their natural compound.
Particularly noteworthy is the fact that only real brewers’ yeast, that is yeast derived from the beer-brewing process - in contrast to other yeasts used in feed - contains extra valuable ingredients from hops (humulone and lupulone).
In addition to the well-known effects of brewers’ yeast, such as
