New generation yeast

Refined version of Progut® produced by stronger hydrolysis which results in a higher content of soluble bioactive structures and thus enhanced biological responses. This gives a possibility to reduce the inclusion rates and makes the product especially suitable for challenging conditions and for ruminant applications.

Overview — Progut® Extra

Stronger Activation

Progut® Extra is a new generation version of Progut® produced by stronger hydrolysis resulting in in higher content of soluble, bioactive structures and enhanced biological responses.

Enhanced Function

Higher content of the soluble molecular yeast structures enhances the efficacy in modulating immunity and both intestinal and ruminal microbiota.

Lower Inclusion – Same Performance boost

Offers the same customer benefits than standard Progut® at lower rate of inclusion. Enhanced efficacy makes Progut® Extra especially suitable for challenging conditions and for ruminant applications.
Mode of Action

A new generation yeast product

Has improved rumen microbial fermentation by increasing the production of microbial biomass and volatile fatty acids, especially propionate.(* This has contributed to improved milk yield and feed efficiency.

Supports the immunity of ruminants.

Supports the immunity of young animals, efficiently binds E. coli and Salmonella bacteria and beneficially modulates the gut microbiota at a low inclusion rate.(*

Action in the rumen

Progut® Extra has increased the production of gas, microbial biomass, and short‑chain fatty acids, especially propionic acid, in numerous in vitro simulation trials. These trials were conducted with different diets and varying concentrate‑to‑silage ratios. The in vitro effects have been verified with the in vivo trials in fistulated cows. Improved rumen fermentation increases the amount of protein and energy that is available for the ruminant and thus improves feed utilization.

In the simulation trials, Progut® Extra stimulated those bacterial groups that were active at the given phase of the simulation. This may indicate Quorum Sensing signaling systems involvement in the regulation of bacterial density. Microbes can produce and release chemical signal molecules by which they communicate and regulate different physiological activities. The hypothesis is that rumen bacteria can recognize increased amount of yeast cell structures as competition and grow in number for better competence.(*

Action in the gut

Immunity

Progut® Extra contains several immune stimulating compounds (β-glucan, mannoprotein and chitin structures) and has increased water-solubility for better visibility to immune receptors. It has shown to increase the recruitment of T-lymphocytes and the immunoglobulin production in the gut. Due to these functions it has enhanced the immune responses of young animals under challenge. Progut® Extra trains the immune system of young animals to cope better with the challenges.

Pathogen binding

Progut® Extra contains similar carbohydrate structures, such as mannose-rich glycoproteins, as the intestinal mucus. These structures in available form provide attachment sites for the fimbriae of pathogens, thus preventing them from attaching to intestinal mucosa. The product has shown outstanding efficacy in preventing the adherence of E. coli and salmonella to intestinal mucus.

Modulating microbiota

In addition, Progut® Extra has shown to beneficially modulate the composition of gut microbiota in sows, piglets and broilers.

Supports the immunity of ruminants

Progut® Extra has reduced somatic cell scores in dairy cows. It has also increased the IgA levels in the colostrum and accelerated recovery of cow’s immune status from calving when fed to dry cows. In calves, Progut® Extra has enhanced immune responses to bacterial and viral challenges. These immune responses can be explained by the high content of several immune stimulating compounds (β-glucan, mannoprotein and chitin structures) which are available to immune receptors due to the unique hydrolysis process.
