Endonase is an enzyme complex developed from Esys Bioferm, a joint venture between Easy Bio System and GNC Bioferm of Canada. It contains high enzymatic activities of a-galactosidase, galactomannanase, xylanase, and B-glucanase that are capable of digesting anti-nutritional factors present in raw materials including corn, soybean meal, copra meal and wheat. therefore it improves the digestion of nutrients resulting to improved performance of animals. It can maximize the nutrient value of raw materials and decrease feed cost through down specification.
