Biological straw feed preparation method

Abstract

The invention relates to a biological straw feed preparation method. The biological straw feed preparation method includes the following steps that 1, crushing is performed: a straw material is smashed by using a smashing machine; 2, pretreatment is performed: the smashed straw material obtained in the step 2 is pretreated, wherein the adopted temperature is 90-130 DEG C, a treating agent is dilute sulfuric acid, peracetic acid, a sodium hydroxide solution or quick lime, and the solid-liquid ratio is 1:10; 3, enzymolysis is performed: the straw material treated in the step 2 is cleaned with distilled water, is dried and then is put into a table for enzymolysis, wherein used enzyme is cellulase and xylanase, the temperature is 30-60 DEG C, the PH is 4-7, the enzyme adding amount is 200-350 u / g, the solid-liquid ratio is 1:10-1:7, and the rotating speed of the table is 100-160 rpm; 4, a biological straw feed is obtained through drying. The biological straw feed can replace or partly replace the corn in a traditional basic diet and plays a positive promoting role on feed digestion.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a method for preparing straw biological feed. Background technique [0002] my country harvests a large amount of straw every year, of which only a very small part is used for industry and other purposes, and most of the straw is used for local fuel and made into farm fertilizer. Because there is no suitable way to use the straw, most of the straw is abandoned on the field. Every spring and autumn, farmers will burn a large amount of straw, and there will be strong black smoke, especially in the farmland in the suburbs of the city. Pollution of urban air, abandonment and burning of straw not only pollute the environment, but also waste valuable biomass resources. Therefore, the development of more and more effective straw utilization methods will provide a wider channel for straw treatment, which has positive significance for reducing environmental pollution and rationa...

Problems solved by technology

[0003] Traditional straw bio-feed research methods are mostly used in silage, micro-storage, yellowing, ammoniation, alkalization, acid storage, etc., to conduct research on straw for ruminant animal feed, and to transform straw into non-ruminal animal feed. Therefore, it is of great practical significance to study a kind of straw bio-feed that can replace or partially replace the corn in the traditional basal diet.
