Question 1

What is ActiSaf® SC 47 HR+ and how does it work?

Accepted Answer

ActiSaf® SC 47 HR+ is a thermostable live yeast probiotic containing the proprietary Saccharomyces cerevisiae Sc 47 strain. It is specially formulated to remain viable during feed pelleting, ensuring more live yeast reaches the animal regardless of feedmill presentation. Once ingested, it supports a balanced rumen or gut microbiota, helping improve fibre digestion, nutrient utilisation and digestive efficiency. By promoting a more stable digestive environment, ActiSaf® SC 47 HR+ helps livestock perform more consistently, particularly during production or environmental challenges.

Question 2

Why is thermostability important in a live yeast probiotic?

Accepted Answer

Many live yeast products lose viability during feed pelleting due to heat, moisture, compression and friction. ActiSaf® SC 47 HR+ is engineered with a patented microspherule technology that provides exceptional intrinsic resistance to these processing stresses without the need for protective coatings. This helps preserve high numbers of live yeast throughout feed manufacture, so producers can have greater confidence that the probiotic remains active when consumed by the animal.

Question 3

What are the production benefits of ActiSaf® SC 47 HR+?

Accepted Answer

ActiSaf® SC 47 HR+ supports rumen efficiency by promoting a stable microbial environment that improves fibre digestion and nutrient utilisation. Numerous research trials have demonstrated benefits including improved feed efficiency and production consistency including times of feed or forage changes and heat stress. A recent meta-analysis (AS 2023) also reported an average increase of 2.4 litres of milk per cow per day when ActiSaf® was fed as directed. These proven performance benefits make ActiSaf® SC 47 HR+ a valuable tool for improving productivity while supporting efficient feed conversion.

Question 4

Which livestock species can benefit from ActiSaf® SC 47 HR+?

Accepted Answer

ActiSaf® SC 47 HR+ is suitable for a wide range of livestock species, including dairy and beef cattle, sheep, goats, pigs and poultry. Its highly thermostable formulation makes it particularly well suited to pelleted feed applications across modern feed manufacturing systems. Whether supporting rumen function in ruminants or gut health in monogastric species, ActiSaf® SC 47 HR+ delivers a versatile probiotic solution for improving digestive performance and production efficiency.

Question 5

Why choose ActiSaf® SC 47 HR+?

Accepted Answer

ActiSaf® SC 47 HR+ combines a proven Saccharomyces cerevisiae Sc 47 strain with intrinsic thermostability to 92°C, making it suitable for both pelleted and mash feeds. Backed by decades of research including published data and extensive commercial validation, it consistently delivers viable live yeast through feed manufacture. Research has demonstrated measurable production benefits, including improved milk yield, while its use alongside effective rumen buffering or neutralising strategies has also enabled complete replacement of ionophores in some production systems, supporting export and retailer requirements where ionophores are restricted.

Question 6

Can live yeast replace ionophores in dairy cattle?

Accepted Answer

In some dairy production systems, yes. When used as part of a balanced nutritional program, ActiSaf® SC 47 HR+ has been shown to support rumen function and production performance without the use of ionophores. When combined with an effective rumen acid neutraliser (pHix-up), it has successfully replaced ionophores in commercial feeding programs, helping producers meet export market and retailer requirements while maintaining productivity. As every herd is different, producers should work with their nutritionist to determine the most appropriate feeding strategy.
