Abstract

The invention discloses a composite enzyme used for feeding piglets. The composite enzyme comprises 100000 to 200000 U/g of xylanase, 8000 to 12000 U/g of dextranase, and 8000 to 12000 U/g of mannase. The invention also discloses a piglet corn-soybean meal ration containing the provided composite enzyme used for feeding piglets. With the composite enzyme provided by the invention, non-starch polysaccharides in rations can be effectively hydrolyzed; nutrients such as proteins and starches in the rations can be effectively digested and absorbed by animals; piglet growth can be promoted; cultivation cost can be reduced; cultivation environment can be reduced; and substantial economic and ecological benefits can be brought in.

Description

technical field [0001] The invention relates to a compound enzyme for feeding, in particular to a compound enzyme for feeding piglets and its application in corn-soybean meal-based diets for piglets. Background technique [0002] my country is the world's largest animal husbandry and breeding country. Further rational allocation and efficient use of feed resources to improve the output, quality and safety of livestock products are the key issues facing my country's animal husbandry and feed industries. In my country, corn and soybean meal are the most important feed raw materials, but there are a large amount of insoluble non-starch polysaccharides in corn and soybean meal. This type of polysaccharide mainly comes from plant cell walls, which can bind a large amount of water and increase the viscosity of chyme in the digestive tract. It makes it difficult for nutrients and endogenous enzymes to diffuse, which not only reduces the digestion and absorption of nutrients such as ...
