Does Live Yeast Actually Increase Milk Yield? The ActiSaf SC 47 Evidence

Yes, but not all yeasts are created equal. A recent global meta-analysis demonstrated that ActiSaf SC 47 increased milk yield by an average of 2.45kg/d ECM. These results have also been replicated in Australian herds.
The Science of Live Yeast
Live yeast works by stabilising rumen pH, improving fibre digestion, and supporting beneficial rumen microorganisms.
Meta-Analysis Results
Key findings for ActiSaf SC 47:
- +2.45 kg/day ECM: Average increase in energy-corrected milk yield.
- Improved fat and protein: Positive effects on milk component percentages.
- Consistent results: Significant responses across different diets, breeds, and management systems.
Australian Validation
ActiSaf SC 47 has been trialled in Australian dairy herds under commercial conditions, confirming the milk yield response observed globally.
Return on Investment
At current milk prices, an additional 2.45 kg/day ECM represents a significant return on the cost of supplementation.
