1.KDN Kingphos (Phytase), to reduce inorganic phosphate supplementation, save cost, reduce P in animal excretion, ease environment pollution. 2.KDN NSP degrading enzyme including Xylanase, Glucanase,Mannanase,Cellulase ,Pectinase ,a-Galactosidase, etc. to decrease NSP present in feed ingredients, reduce chyme viscosity, increase growth performance of animals 3.KND exogenous digestive enzymes including a-Amylase, Acid protease, Lipase, etc. as a supplement to endogenous digestive enzymes, improve the utilization of nutrient, enhance growth performance. 4.KDN Kingzyme (Compoud feed enzymes), to degrade NSP present in feed ingredients, supplement endogenous digestive enzyme, enhance nutrient utilization. 5. KDN Greensafe and Lifesafe (Formulated Probiotics, mainly composed of Bacillus Subtilis, Bacillus Licheniformis, and Lactobacillus), to inhibit grow of pathogenic bacteria, balance gut stability, enhance immunity and growth performance, decrease intestinal harmful gas and offens
