Problems solved by technology

At the same time, the nutritional content of straw feed is relatively low, which is characterized by low crude protein, fat and sugar content, low energy value, and high fiber content. The crude fiber is as high as 30% to 45%, and the degree of lignification is relatively high. , hard and rough texture, poor palatability, and indigestibility, which lead to the problem of low utilization rate of straw
[0003] After searching, the relevant patents in this field are: 1. Chinese patent application (95118343) discloses a high-protein saccharified feed and its preparation method. The invention uses strong acid and strong alkali for degradation, and uses active yeast fermentation to increase the protein content; The acid and alkali corrosion of this method is serious, and the nutrients of the straw cannot be fully degraded, and the protein content is not much improved.
2. Chinese patent application (98118918) discloses a production method of high-protein saccharification biological feed of crop stalks. This invention also uses strong acid and strong alkali to degrade, and then uses Trichoderma, Aspergillus and yeast mixed fermentation to increase protein content; the method Also, the acid-base corrosion is serious, the nutrients of the straw cannot be fully degraded, and the protein content does not increase much.
3. Chinese patent application (99111172) is a biological feed production agent and its use method, which uses chemical additives such as glucoamylase, softener, and strong alkali to soften the straw, and then uses microorganisms to improve the nutritional value of the straw; this method also exists Acid-base corrosion is serious, and straw nutrients cannot be fully degraded. At the same time, alkaline conditions are not conducive to the growth and utilization of microorganisms.
[0004] At present, the processing methods such as silage, micro-storage, yellow storage, acid storage, ammoniation, and alkalization of corn stalks are studied, all of which use microbial fermentation to produce enzymes to fully degrade cellulose, hemicellulose, lignin, etc. in corn stalks into However, the above methods have the problems of long fermentation period, easy to rot, difficult to store, and pollute the environment in the production process, which affects the effective utilization of straw

Abstract

The invention relates to a method for preparing high-protein sacchariferous feed by straws, which is characterized in that a straw powder raw evaporating material is mixed with complex enzyme; after carrying out saccharification hydrolysis, the product is accumulated and fermented by saccharomyces cerevisiae and lactobacillus planetarium; after the product is dried or granulated, the high-protein sacchariferous feed is obtained. Compared with the prior art, the invention fully utilizes nutrient in the straws, improves a nutrient component of the feed, and is beneficial to the digestive absorption of livestock, wherein the crude protein content is improved to more than 21 percent, and the crude fiber content is lower than 14 percent; the dosage proportion of the straw feed in mixed feed and special feed can be improved, the dosages of concentrated feed and grain are saved; an experiment indicates that by adding 5 percent of sacchariferous feed into pig feed, the weight can be increased by 6 percent, the economic benefits are improved by 12 percent, and the grain is saved by more than 65 percent; meanwhile, inherent resources of the straw are fully utilized, and the utilization ratio of the resources is improved; by reasonably utilizing the straws, the problem of environmental pollution caused by discarding and burning the straws is effectively solved; and the invention has the characteristics of simple and convenient operation, high degradation utilization ratio of the straws, high protein saccharide content, low cost and no environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of straw feed processing, in particular to the improvement of the method for preparing straw feed by using enzyme technology. Background technique [0002] my country's crop sown area ranks first in the world. In 2008, the output of various crop straws was about 720 million tons, of which corn straw was 182 million tons. In traditional agriculture, corn stalks are mainly used as fuel in rural areas. In recent years, some of the stalks have been returned to the fields, but the total amount is not large. A large number of corn stalks are discarded in the fields or burned, resulting in waste of resources and serious environmental pollution. Straw is an important source of roughage for herbivorous livestock. Improving the nutritional value and feed utilization rate of straw can solve the problem of straw utilization and reduce environmental pollution. It is an effective way to solve the dependence of animal husb...
