Abstract

The invention discloses a feed complex enzyme containing alkaline xylanase and a preparation method thereof and belongs to the technical field of enzyme preparations. The feed complex enzyme is prepared by scientifically compounding concentrated maltase, acid proteinase, alkaline xylanase, acidic xylanase, cellulose, beta-glucanase, pectinase, amylase, mannose, phytase, Chinese herb extracts, a protective agent and an activating agent. Alkaline xylanase has broad action conditions and strong thermal stability and is more suitable for animal growth. The feed complex enzyme provides a safe digestive enzyme for livestock and poultry, can be used for effectively reducing digestion burden, improving the utilization rate and growth rate of raw materials, effectively protecting the environment, bringing natural malt fragrance for the feed and increasing the appetite of livestock and poultry; a proper amount of activating agent can be used for fully exerting the effectiveness of an enzyme preparation under the equal condition and making the best of the raw materials; the addition amount of the enzyme preparation is saved; by virtue of the scientific compounding of the Chinese herb extracts, not only can the guarantee period of the complex enzyme preparation be prolonged, but also the immunity of the fed livestock and poultry can be improved.

Description

technical field [0001] The invention belongs to the technical field of enzyme preparation, in particular to a feed compound enzyme containing alkaline xylanase 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 degraded by the anima...
