Question 1

What is Saccharomyces boulardii and why is it different from other probiotics?

Accepted Answer

Saccharomyces boulardii is a specific probiotic yeast strain with decades of scientific research supporting its role in maintaining digestive health. Unlike many bacterial probiotics, it remains active during periods of gastrointestinal stress and helps support a balanced gut microbiome. Its specialised properties have made it widely used in human, livestock and equine nutrition where maintaining normal digestive function is a priority.

Question 2

When should I use Saccharomyces boulardii for calves, foals or young livestock?

Accepted Answer

4PRO™ YEAST SB20 is best introduced before predictable periods of digestive or environmental stress, such as birth, transport, milk transitions, weaning and weather changes. It can also provide valuable nutritional support during digestive challenges when maintaining a balanced gut microbiome is especially important. Early supplementation helps support gut resilience when the gastrointestinal ecosystem is most vulnerable.

Question 3

Can Saccharomyces boulardii support calves during digestive challenges?

Accepted Answer

Scientific studies have demonstrated that Saccharomyces boulardii supplementation can help reduce the incidence and duration of diarrhoea in young calves while supporting a healthier intestinal microbiota. Calves experiencing diarrhoea commonly develop an imbalance of gut microbes, including overgrowth of opportunistic bacteria such as E. coli. By helping maintain microbial balance and normal gut function, S. boulardii provides valuable nutritional support during periods of digestive challenge.

Question 4

Is 4PRO™ YEAST SB20 suitable for foals and horses?

Accepted Answer

Yes. Saccharomyces boulardii is widely recognised in equine nutrition as a probiotic yeast that supports digestive health during periods of gastrointestinal or environmental stress. Studies have shown the yeast survives passage through the equine digestive tract while being safely administered as nutritional support. Because probiotic yeasts do not permanently colonise the gut, consistent supplementation during periods of challenge is recommended to maintain their beneficial effects.

Question 5

Why is Saccharomyces boulardii often recommended during calf scours and digestive challenges?

Accepted Answer

Digestive upsets such as calf scours can rapidly disrupt the normal gut microbiome, allowing opportunistic bacteria, including E. coli, to proliferate. Research has shown Saccharomyces boulardii helps support microbial balance, intestinal integrity and normal digestive function during these periods. While it is not a treatment for disease, its targeted digestive support is why an additional inclusion of 4PRO™ YEAST SB20 is incorporated into BEST START™ ElectroCALF, complementing fluid and electrolyte replacement during periods of gastrointestinal challenge.
