Unique autolyzed yeast 

Levabon® Rumen E enhances rumen activity by increasing beneficial rumen bacteria, stabilizing pH and improving feed digestion, leading to higher animal productivity.

Proprietary autolysis for Levabon® Rumen E provides the optimal conditions for enzymatic reactions to break down whole yeast cells into fragments. This provides immediately available bioactive and prebiotic compounds to stimulate beneficial rumen microbiota.

Gut Performance Management
Whole intact yeast cells
Conventional whole intact yeast cells
After autolysis, yeast with broken cells; bioactives and prebiotics immediately available
Autolyzed Levabon® Rumen E yeast cells mean that bioactives and prebiotics are immediately available to the animal
