RFN WS
The live-yeast probiotic you ferment on your own farm
Active culture of Saccharomyces cerevisiae, rehydrated and fermented for 12 hours on the farm. What reaches the animal is a broth of fresh metabolites.
When digestive balance breaks down
Weaning, the move into fattening, peak lactation or any high-performance phase expose the animal to a digestive imbalance: undesirable bacteria gain ground and feed efficiency drops.
Diet and group change at the same time.
The cow eats more and the rumen works at its limit.
Heat stress also takes its toll on digestion.
Five reasons to ferment it on the farm
Improves the use of nutrients and zootechnical performance in all three species.
Helps limit the proliferation of undesirable bacteria such as E. coli, clostridia or salmonella.
Helps counteract the toxic effect of mycotoxins present in feed.
Improves resistance to heat stress and, in high-performance cattle, helps reduce the risk of acidosis.
Naturally sourced ingredients with no known side effects, which do not generate resistance.
What reaches the animal is the fermented broth
During the 12 hours of fermentation the yeast multiplies and generates fresh metabolites that favour the predominance of beneficial microbiota and strengthen intestinal cell activity and integrity.
Live yeast
Saccharomyces cerevisiae at 10⁹ CFU/g, reactivated in the fermenter.
Fresh metabolites
B-group and K vitamins, proteins and peptides that support immunoglobulin A production.
Its own substrate
Dextrose and lactose feed the yeast during fermentation.

Fermented for 12 hours before use
Add 20-25 litres of water at room temperature to a fermenter, add the RFN WS dose, leave to ferment for 12 hours, allow to cool, and give in the drinking water, over the forage or in the TMR wagon. Label dose:
On a farm with 50 dairy cows, the daily dose amounts to 500 g of product, prepared in a single 20-25 litre fermenter and distributed through the drinking trough or the TMR.

Transparency in every ingredient
Composition
Dextrose, lactose, magnesium carbonate and ammonium phosphate.
Additive
Saccharomyces cerevisiae, 10⁹ CFU/g.
Analytical constituents
Crude protein 4.4 %; crude fibre 0.8 %; crude oils and fats 0.5 %; crude ash 1.7 %; calcium below 0.02 %; phosphorus 0.23 %; sodium 121 mg/kg; magnesium 4,300 mg/kg; lysine and methionine below 0.1 %.
How the formula works
The live yeast reactivates during fermentation; dextrose and lactose are its substrate, and magnesium carbonate and ammonium phosphate stabilise the culture medium.
Peace of mind, every day
Naturally sourced ingredients with no known side effects, which do not generate resistance.
Always give the fermented, cooled broth, never the dry powder.

Can't find your answer? Write to us and our technical team will reply.
How is RFN WS prepared?
Add the dose to 20-25 litres of water at room temperature in a fermenter, leave to ferment for 12 hours, allow to cool, and give it in the water, over the forage or in the TMR.
What is the dose for each species?
According to the label: 10 g per cow per day, 5 g per animal per day in beef cattle, 2 g per ewe per day and 1 g per piglet per day.
How long is it used for?
During the productive lactation period, for a maximum of ten months.
How should it be stored?
Unfermented, in its original tightly closed packaging, in a cool, dry place, away from heat and sunlight. Shelf life of 12 months from manufacture.
Does it replace veterinary treatment?
No. It is a complementary feed that fits into farm management and does not replace the diagnosis or judgement of the veterinarian responsible.
