Abstract

The invention discloses a feed compound enzyme containing neutral protease and a preparation method thereof, and belongs to the technical field of preparation of an enzyme preparation. The feed compound enzyme containing neutral protease is prepared from concentrated malt enzyme, acid proteinase, neutral protease, acidic xylanase, cellulose, beta-glucanase, pectinase, amylase, seminase, phytase, Chinese herb extracts, a protective agent and an activating agent in a scientific distribution manner. The feed compound enzyme is high in enzyme activity, wide in action condition, strong in stability, and more applicable to feed production. A safe digestive enzyme can be provided for beasts and birds, the digestion burden is relieved, the utilization rate and the growth rate of the raw materials are improved, the environment is protected, joyful natural malt fragrance is brought for the feed, the livestock and poultry appetite is enhanced, meanwhile, the efficacy of the enzyme preparation can be fully played by proper quantity of activating agent under the same condition, the adding amount of the enzyme preparation is saved, the expiration date of the compound enzyme preparation is prolonged by scientific distribution of the Chinese herb extracts, and the immunity of the fed beasts and birds can be improved.

Description

technical field [0001] The invention belongs to the technical field of preparation of enzyme preparations, in particular to a feed compound enzyme containing neutral protease and a preparation method thereof. Background technique [0002] There are four main reasons for adding enzyme preparations to feed: 1. Degradation of anti-nutritional factors present in animal feed. These substances cannot be degraded by animal endogenous enzymes, thereby interfering with the normal metabolism of animals, resulting in indigestion of animals and decreased production performance. 2. Improve the utilization rate of starch, protein and minerals. These substances are either surrounded by fiber-rich cell walls, or are present in certain structures that cannot be digested by animals (for example, in plant feed materials, a large amount of phosphorus is present in the form of phytate phosphorus.). 3. Degrade some specific chemical bonds in raw materials. These chemical bonds cannot be degrad...
