Question 1

What is ActiSaf® SC 47 INST and how does it benefit young calves?

Accepted Answer

ActiSaf® SC 47 INST is an instant-dispersing live yeast probiotic (Saccharomyces cerevisiae CNCM I-4407) specifically formulated for calf milk feeds and other liquid feeding applications. It supports digestive health by promoting a balanced gut microbiota during the critical pre-weaning period, helping calves utilise nutrients more efficiently. Commercial trials have demonstrated improvements in average daily gain (ADG) of up to 24%, together with fewer bacterial and protozoal scour episodes and reduced veterinary treatments, supporting healthier calves and improved rearing performance.

Question 2

Why use a live yeast probiotic in calf milk feeds?

Accepted Answer

The milk-fed period is critical for establishing a healthy digestive system. Supplementing calf milk feeds with a proven live yeast probiotic helps support a balanced intestinal microbiome, improves digestive function and enhances nutrient utilisation when calves are most vulnerable to digestive challenges. ActiSaf® SC 47 INST is specifically formulated for rapid dispersion in liquid feeds, ensuring consistent delivery of live yeast cells that help maintain gut health, support immunity and promote stronger early-life growth and resilience.

Question 3

Can ActiSaf® SC 47 INST help reduce calf scours?

Accepted Answer

Yes. Research (VAS 2024) and commercial field trials have shown that ActiSaf® SC 47 INST supports intestinal health by helping maintain a balanced gut microbiota and reducing populations of harmful microorganisms. Supplemented calves experienced fewer bacterial and protozoal scour episodes, lower veterinary treatment requirements and improved health throughout the pre-weaning period. By strengthening digestive resilience during this critical stage, ActiSaf® SC 47 INST helps minimise health setbacks while supporting consistent growth and calf welfare.

Question 4

How does ActiSaf® SC 47 INST improve calf growth and average daily gain (ADG)?

Accepted Answer

Healthy digestion underpins efficient growth. ActiSaf® SC 47 INST promotes a stable gastrointestinal micro-flora environment, enabling calves to utilise nutrients more effectively during the milk-feeding phase. Research (VAS 2024) and commercial trials have demonstrated improvements in average daily gain (ADG) of up to 24%, alongside better digestive health and reduced health-related setbacks. By supporting nutrient utilisation rather than increasing feed intake, ActiSaf® SC 47 INST helps producers maximise calf performance while building a strong foundation for future productivity.

Question 5

How does ActiSaf® SC 47 INST support calves through weaning?

Accepted Answer

Weaning is one of the most challenging periods in a calf's life, requiring the digestive system to transition from milk to solid feed. ActiSaf® SC 47 INST helps establish a healthy gastrointestinal environment before weaning, supporting digestive stability throughout this transition. Healthier calves are better able to maintain feed intake, continue growing and adapt to dietary change with fewer digestive disruptions. This supports the transition to functional rumen development and lays the foundation for improved long-term health and lifetime productivity.
