CELMANAX is a unique combination of a yeast culture and RFCs (refined functional carbohydrates). CELMANAX improves both rumen digestion and intestinal health. The yeast culture takes care of the rumen function, while the RFCs are responsible for the intestinal function. RFCs are formed through the enzymatic hydrolysis of the yeast cell wall and only become available through this process. For enzymatic hydrolysis, three different exogenous enzymes are added to the cell walls at different pH values ​​for defined times to break them down. The RFCs contain D-mannoses, mannan oligosaccharides (MOS), ß-glucans, and amine compounds.
