The invention belongs to the technical field of feed additives, and in particular relates to complex enzyme for a feed. The complex enzyme comprises 7,500 to 15,000U/g of xylanase, 1,000 to 3,000U/g of mannose, 50 to 80U/g of galactosidase, 200 to 700U/g of cellulose, 500 to 1,500U/g of beta-glucanase, 150 to 1,000U/g of alpha-amylase, 2,000 to 10,000U/g of protease and 100 to 200U/g of pectinase. By adding corresponding enzyme preparations, the anti-nutrition function of the complex enzyme is reduced, the feed utilization is improved, and the animal production efficiency is improved, so the problems that the utilization rate of animal feed raw materials is low and the animal production performance is inhibited are effectively solved; meanwhile, the complex enzyme has the advantages of reasonable raw material mixing, good effect, and low overall cost.
