A kind of preparation technology of microbial straw feed

Abstract

The invention relates to a preparation technology of a microorganism straw feed. The preparation technology of the microorganism straw feed comprises the following steps: preparing a microorganism bacterium agent, removing impurities of straw raw materials, crushing the straw raw materials without impurities, adding the microorganism bacterium agent, stirring the microorganism bacterium agent and the crushed straw raw materials without the impurities so as to obtain a mixture, sealing the mixture, and fermenting the sealed mixture so as to obtain the microorganism straw feed. The straw raw materials of the microorganism straw feed are wide in sources, and fresh straws of which the water content is 12-78%, naturally dried straws and dried mildewed straws can be processed; the preparation method is simple and clean, the cost is low, products can be stored for 6-12 months, and the products can be transported for a long distance; the straw feed disclosed by the invention has the effects of promoting livestock to grow, enhancing the disease resistance of the livestock, relieving the odor of excrement in breeding houses, and improving the quality of livestock meat.

Description

technical field [0001] The invention belongs to the technical field of microbial degradation, and in particular relates to a preparation process of live microbial straw feed. Background technique [0002] According to statistics, more than 800,000,000 tons of stalks are produced in my country every year. After using various treatment methods such as straw vaporization, lightweight building materials, direct return to the field, straw tableware, straw feed, etc., 31.3% of the straw is still used as agricultural solid waste because it cannot be properly treated. Year after year, a large number of burnings have been repeatedly prohibited. Straw burning not only wastes resources, but also causes serious political, economic and social harm. Changing rapidly and calling for better stalk processing new technologies to come out as soon as possible has become an extremely urgent common voice of the people of the whole country for a long time, and more serious ones have appealed to t...

Problems solved by technology

[0003] At the same time, my country imports a large amount of forage grass from the United States, Australia, Spain, Canada and other countries every year. In 2014, it imported 1 billion kilograms and consumed 383 million US dollars of foreign exchange. It is mainly used for raising livestock such as dairy cows. Increase year by year, consume a lot of foreign exchange, waste a lot of straw biological resources and the gap between the demand for high-quality forage needs to be bridged

[0004] The technical defects reflected in the application practice of existing feed production technologies such as ammonification, alkalization, micro-storage, silage and straw pellet feed are mainly the following problems: ① Except for straw pellet feed technology, several other This method can only handle very few fresh stalks in local areas, and cannot solve the problem of dealing with more straws with different moisture contents widely and in large quantities; The warehouse is very easy to be moldy and corrupted and can only be discarded, and the resulting waste is a big problem; ③The moldy and corrupted feed quality and palatability are reduced, it is difficult to keep fresh for a long time, and it cannot be transported long-distance to form a market-oriented operation; ④ In particular, straw ammoniated feed technology products are more prominent in practical applications because of their high toxicity, poor taste, and even dangers such as poisoning or fire. The defects are huge and they are facing elimination; Large-scale, resource utilization, the problem that straw feed cannot open up the market

[0005] Microbial fermentation is a biomass feed conversion technology that has been widely used in recent years. However, the existing microbial fermentation technology is only suitable for fresh straw, which is mainly produced during the straw harvest season, or other biomass raw materials. The species is not a live strain, the strain is single, and the fermentation effect is not good
