Thepax Biolase is Saccharomyces cerevisiae Var. ellipsoideus with Inulin. Thepax Biolase performs well on pigs because the cell content will activate and benefit the resident microflora in the large intestine almost in the same way that it benefits rumen microflora. While Thepax Biolase offers major benefits in terms of weight gain and increasing FCR's the additional benefits include its ability to reduce the reliance on therapeutic treatments, especially for those related to diseases of the digestive tract in swine.
