Actisaf (specific strain Saccharomyces cerevisiae Sc 47) is the market leader in protected live yeast. Actisaf is produced by a unique Lesaffre manufacturing process that ensures a better stability, which means that more yeast cells reach the rumen and intestine alive.


Selyeast 3000 is a yeast rich in organic selenium (Se), mainly selenomethionine, which is highly bioavailable.
Selyeast 3000 protects against oxidative stress. It is efficient for developing embryo and the health of the newborn thanks to a better transfer of the Se from the diet to the egg and the colostrum/milk. It provides additional protection due to Se reserves under stress conditions.
Safmannan is a source of mannanoligosaccharide and betaglucans derived from yeast cell wall. It originates from a specific strain of yeast.
Safmannan stimulates the growth of beneficial bacteria in the gut and improves the immune status of the animal. In addition, it acts as a specific binder, reducing the negative effect of mycotoxins and pathogens in the digestive system of the animal.






Lesaffre is seen as a reference in the yeast and bread-making fields. Its knowledge of yeast and its expertise in the fermentation have encouraged the Lesaffre group to establish a presence in the emerging human and animal nutrition markets.
