Abstract

The invention provides biological straw feed and a preparation method thereof. The method for preparing the biological straw feed comprises the following steps: mixing yeasts, lactic acid bacteria, crop straws, magnetic water and a magnetized compound enzyme system, thereby obtaining a mixture; and fermenting the mixture, thereby obtaining the biological straw feed. The method for preparing the magnetized compound enzyme system comprises the following steps: magnetizing cellulase, protease, amylase, dextranase, pectinase and ligninase in a permanent magnetic field, thereby obtaining the magnetized compound enzyme system. In the process of preparing the biological straw feed, the biological fermentation technology is combined with the magnetization technology, fermentation of the crop straws can be effectively realized, and the activity of the compound enzyme system in the crop fermentation process is prevented from being reduced, so that the protein conversion rate is high. Therefore, the nutritional ingredients of the crop straws are fully converted.

Description

technical field [0001] The invention relates to the technical field of biological material reuse, in particular to a biological straw feed and a preparation method thereof. Background technique [0002] In rural areas of our country, crop stalks, mainly corn, wheat and rice, can be seen everywhere. According to incomplete statistics, the annual output of crop straw in my country is nearly 700 million tons. Except for a small amount used as roughage for ruminants, most of them are directly burned, which not only causes waste of resources but also pollutes the environment and causes soil compaction. [0003] In the past, crop stalks were mainly used in direct feeding, which led to waste of nutrients, poor palatability and low feed intake. In recent years, people have done a lot of research on how to improve the palatability of straw feed and make full use of its nutritional value. However, both physical and chemical methods have shortcomings and shortcomings. [0004] With t...
