Problems solved by technology

Therefore, the degradation efficiency of arabinoxylan in wheat by single xylanase is low
Chinese Patent Publication No. CN103725662A discloses a wheat dietary enzyme containing alkaline xylanase and a preparation method thereof. Although the weakly alkaline environment in the intestinal tract of livestock and poultry is considered, the invention still only includes a single xylanase Glycanases that do not contain enzymes that target arabinoxylan branched chains
Therefore, the structure of arabinoxylan is not targeted, and its degradation efficiency is still not high

Abstract

The invention relates to a wheat based diet specific xylan degradation compound enzyme preparation. The active component of the wheat based diet specific xylan degradation compound enzyme preparation comprises xylanase and arabinfuranosidease and / or ferulic acid esterase. The invention aims at preparing the wheat based diet specific araboxylan degradation compound enzyme preparation according to the structural features of the wheat araboxylan, and the utilization effect of poultry to wheat is targetedly improved. By means of the specific xylan degradation compound enzyme preparation, the utilization effect of the wheat is improved, proliferation of beneficial bacteria such as intestinal lactic acid bacteria and the like is further facilitated, intestinal health is achieved, and the production performance of the poultry is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry breeding and feed preparation, and in particular relates to a wheat ration-specific xylan-degrading composite enzyme preparation and a preparation method and application thereof. Background technique [0002] my country is a big country of livestock and poultry breeding. With the development of my country's breeding industry, a large amount of compound feed needs to be consumed every year. In 2014, my country's feed production reached 15,000 tons. Although wheat is mainly used as a food source for Chinese residents, it has high protein content and often has a price advantage compared with corn. It is often used as a common feed material for livestock and poultry, and is widely used in the production of livestock and poultry feed. Internationally, in Europe, Australia and other countries with a small corn planting area, wheat is also widely used as one of the raw materials for livest...
