Abstract

The invention discloses a neutral protease-containing coarse grain daily ration enzyme and a preparation method thereof, belonging to the technical field of preparation of enzyme preparation. The coarse grain daily ration enzyme is prepared by scientifically compounding bacillus subtilis culture, acidic xylanase, beta-glucanase, acidic protease, pectinase, cellulose, amylase, Chinese herb extracts, a protective agent and an activating agent, wherein the bacillus subtilis culture has the functions of improving animal organism immunity, promoting the development of immune organs and the maturity of animal intestinal tract structure and function and improving the animal daily gain and the feed conversion rate. After the neutral protease-containing coarse grain daily ration enzyme is adopted, safe digestive enzyme is provided for livestock and poultry, the digestion burden is effectively lightened, the utilization rate and the growth rate of the raw materials are improved, and the environment is protected; furthermore, the right amount of activating agent gives full play to the effect of the enzyme preparation under the same condition, so that the add amount of the enzyme preparation is reduced; the Chinese herb extracts are scientifically compounded, so that the shelf life of the compound enzyme preparation can be prolonged, and the immunity of the raised livestock and poultry can be improved.

Description

technical field [0001] The invention belongs to the technical field of enzyme preparation, and in particular relates to a miscellaneous grain dietary 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...
