ADM highlights unique yeast benefits at EuroTier 2016
While most other yeast products in the market are made from Saccharomyces cerevisiae, ADM's CitriStim® is made from a unique yeast species used in the company's citric acid fermentation process.
The benefits provided to animals by this unique yeast species, Pichia guilliermondii, were highlighted by Dr. Manfred Peisker, Director ADM Nutrition Europe, Middle East & Africa, at EuroTier 2016 in Hannover, Germany.
Pichia guilliermondii is a co-product of ADM's food-use manufacturing process for citric acid and has been FAMI-QS certified. Consequently, ADM can provide the assurance that its yeast product is of a consistent quality, especially when compared to spent yeast sources from different breweries or ethanol plants.
Importantly, yeast cells of Pichia guilliermondii are a quarter in size compared to those of Saccharomyces cerevisiae, according to Dr. Peisker. This means that Pichia guilliermondii at equal dose level provides significantly higher surface area to adhere to pathogens, rendering them unable to bind to and infect intestinal cells, making it a more effective product than Saccharomyces cerevisiae products.
In trials conducted on broilers and piglets, there were up to 80% reduction in harmful E. coli and Salmonella in mucus, compared to pure mannose, which is considered the gold standard in adhesion prevention trials.
As he summarizes, yeast is not part of an animal's normal diet, and therefore can act as stimulant to the innate immune system, priming it for possible infection. Since Pichia guilliermondii is very effective, Dr. Peisker suggests an inclusion rate of 0.1% up to a maximum of 0.2% in appropriate circumstances.
