Levucell SC is a natural and well documented rumen specific live yeast (Saccharomyces cerevisiae CNCM-1077). Levucell SC is classified as an active dry yeast; the strain has been selected from among thousands of strains for its high capacity to improve rumen function. It has been validated by leading research centers and more than 60 scientific publications.
Levucell SC mode of action
Levucell SC improves rumen function through several mechanisms:
- Increased fiber digestibility
- Increased rumen pH, reducing the incidence of acidosis
- Improved rumen health
Increased fiber digestibility
The rumen specific live yeast Levucell SC stimulates fiber digesting microbes, their enzymatic activity, and fiber digestibility; this results in maximizing energy from the forage and the diet with improved feed efficiency.
Schwartz et al, 2002
Increased rumen pH, reduced incidence of acidosis
Levucell SC increased rumen pH. Subclinical acidosis occurs when the rumen pH falls below 5.6.
Chaucheyras-Durand et al, 1997
Improved rumen health
By stabilizing rumen equilibrium and limiting risk of acidosis, Levucell SC improves the integrity of the rumen walls and its papillae.
Damaged rumen
Healthy rumen
Levucell SC for the calf
A faster establishment of rumen microbial communities results in improved feed intake and feed digestions.
Chaucheyras-Durand et al, 2002
The use of Levucell SC has been shown to increase feed intake and weight gain and decrease the incidence of digestive problems. This case was clearly shown in a calf trial at the University of California, Davis (Santos et al, 2003).
Levucell SC for growing cattle
Levucell SC for growing cattle maximizes growth potential through:
- Increased average daily weight gain
- Optimized feed efficiency
- Reduced overall morbidity
A recent meta-analysis summarized the results of international trials:
Levucell SC improves feed efficiency and average daily gain in growing cattle fed high roughage diets.

Levucell SC for finishing cattle
In conventional finishing diets containing Monensin, Levucell SC further improves feed efficiency.
