Preparation method for preparing stalk protein feedstuff with microorganism stalk leaven

Abstract

The invention relates to a preparation method for producing straw protein feed by using microorganism straw fermenting agents, which belongs to a preparation method of producing organism feed by microorganism technical transform. The preparation process of the method is as follows: inclined strain variety, test-tube liquid strain variety, primary liquid culture, secondary culture, liquid culture, fermentation tank or vat liquid, solid fermentation, drying, crushing strain culture. Crop straws of China are used fully through physical action and biological action, and are transformed into high nutritious biological feed to replace grain. The straw protein feed with microorganism straw fermenting agents has the advantages of low cost, wide raw materials, short fermentation period, easy popularization, simple and convenient operation, great adaptability and so on.

Description

technical field [0001] The invention relates to a preparation method for producing straw protein feed with a microbial straw starter, which belongs to a preparation method for producing biological feed through transformation of microbial technology. Background technique [0002] How to develop and utilize straw (straw) is an important research topic in the world today. Since the beginning of the 20th century, the conversion and processing technology of straw feed at home and abroad has developed rapidly. According to the statistics of the Food and Agriculture Organization of the United Nations, meat is made of grass. The conversion ratio is about 73% in the United States, about 90% in Australia, and only 6%-8% in my country. With the prosperity of the market economy, the aquaculture industry in my country has developed rapidly, but the area of ​​cultivated land is decreasing year by year. Constrained by high food prices, the situation of my country's feed industry is particula...

Problems solved by technology

[0003] Rice straw is the main source of roughage in southern my country, and its nutritional value is lower than that of wheat straw and forage. Rice is the largest food crop in my country, so the utilization of straw is particularly worthy of attention. The digestibility of straw to cattle and sheep is about 50%. , the digestibility of pigs is generally below 20%. If certain biological treatment is carried out, it can be turned into feed with better palatability, especially feed for cattle, sheep, geese, rabbits, pigs, chickens and ducks. The effect is good. As we all know, Ruminants such as cattle and sheep have a lot of rumen microorganisms, they can use straw as feed, but due to many factors such as low straw digestibility and low feed intake, their use value is reduced. In order to use a large amount of straw as feed, domestic Many scientific workers outside China have invested a lot of energy and financial resources, such as the use of acid-base chemical treatment, silage, micro-storage, and ammoniation. These methods have achieved certain results, but they have not achieved substantial breakthroughs. The reason is that so far Can't find a really reliable way to reduce the cellulose and lignin of straw, that's the problem we're currently waiting to solve
