RupriVia™ – Rumen-Specific Active Dry Yeast for Improved Rumen Efficiency

Support Rumen Balance Through Dietary and Environmental Challenges

Rumen efficiency depends on a stable and balanced microbial population. Changes in diet, environmental stress and inconsistent feeding conditions can disrupt rumen function, impacting digestion, nutrient utilization and overall animal performance.

RupriVia™ is a rumen-specific active dry yeast designed to support bacterial adaptation during dietary transitions and challenging field conditions. By helping maintain rumen balance, RupriVia supports fermentation, nutrient utilization and consistent performance in dairy and beef cattle.

Features & Benefits

2697458795
  • Stable rumen fermentation by helping maintain a balanced rumen environment. 
  • Improved dry matter intake, also known as DMI, by supporting rumen comfort and digestion. 
  • Enhanced nutrient digestibility through improved fiber breakdown and microbial activity.
  • Better feed efficiency and feed conversion ratio, also known as FCR, by helping animals convert feed into usable nutrients. 
  • Consistent performance under field conditions, including ration changes, heat load and inconsistent forage quality.
  • Improved milk yield and milk composition through optimized rumen fermentation and volatile fatty acid production.

Why Does Rumen Stability Matter for Dairy and Beef Cattle?

The rumen depends on a stable and diverse microbial population to support fiber digestion, volatile fatty acid production and nutrient utilization. When this microbial balance is disturbed, beneficial fiber-digesting microbes may decline while lactic-acid-producing or opportunistic organisms increase.

This imbalance can contribute to:

  • Reduced fiber digestion 
  • Lower microbial protein synthesis 
  • Less efficient nutrient utilization
  • Increased volatile fatty acid and lactic acid buildup
  • Unpredictable performance in milk yield and feed efficienc

How RupriVia Works

Rumen-Specific Active Dry Yeast Technology

Active dry yeast plays a functional biological role within the rumen by influencing fermentation conditions, supporting microbial balance and improving microbial protein synthesis.

RupriVia utilizes a scientifically selected strain of Saccharomyces cerevisiae that has been specifically adapted for rumen conditions through strain screening and performance evaluation.

This rumen-specific strain helps:

  • Support beneficial fiber-digesting microbes
  • Improve fermentation efficiency
  • Support anaerobic rumen conditions
  • Contribute to microbial balance
  • Enhance nutrient utilization

What Makes RupriVia Different?

RupriVia was developed specifically for ruminants to support rumen stability, nutrient utilization and consistent performance under practical feeding conditions.

The 3S approach of RupriVia — Strong. Stable. Scientific. — integrates strain selection and processing technology to deliver superior stability and performance.

  • Strong: A scientifically selected yeast strain optimized for the rumen environment. RupriVia is designed to survive feed processing conditions, including pelleting temperatures, while maintaining performance.
  • Stable: Provides reliable performance across seasons, feeding programs and environmental conditions. Suitable for pelleted feed, total mixed rations (TMR) and on-farm mixing.
  • Scientific: Developed through strain selection and processing technology to help support rumen efficacy, microbial balance and consistent animal performance.

RupriVia Is Designed for Practical Farm Conditions

Whether animals face ration changes, heat stress, inconsistent forage quality or other environmental challenges, RupriVia helps support rumen balance and fermentation stability. This consistent support helps maintain performance when conditions are less than ideal.
