The invention provides a corn bean pulp type feed complex enzyme additive and an application thereof. The complex enzyme additive comprises the components based on weight percentage: 10%-15% of xylanase, 8%-15% of cellulase, 3%-8% of beta-seminase, 5-15% of alpha-galactosidase, 5%-10% of acid protease, 10%-20% of moderate temperature amylase, 5%-10% of glucoamylase and 7%-54% of carrier. The complex enzyme additive can decompose the nutrient s in the corn bean pulp, a mass of anti-nutritional factors which are hard to digest by animals such as the crude fiber and the like, so that energy in the corn bean pulp can be abundantly explored, the digestion capability of the animals to the corn bean pulp type feed can be improved, and the material-meat ratio can be reduced; the digestibility of the nutrient substance and the appearance metabolic energy can be improved, and the microorganism quantity of the ileum can be reduced; the corn bean pulp type feed complex enzyme additive has the advantages of being high-efficiency, specific, small in additive amount and the like compared with the similar additive; and after the complex enzyme additive is used, the growth of the animals can be promoted, and the feed converting efficiency can be improved.
