Cultron is the Aleris’s product specially formulated with yeast culture (Saccharomyces cerevisiae) fermented from corn derivatives and cane molasses in a controlled nutrient medium. This technological process maximizes yeast metabolic activity increasing the biological value of final product. As a result, Cultron provides a higher energetic content, mainly due leucine, valine and isoleucine that work as a substrate for ruminal bacteria degrading fiber. The nutritional composition fullness (amino acids, vitamins, enzymes and organic acids) makes Cultron an excellent product to promote growth and profitability of ruminants.
