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 mic

Embodiment 1

[0024] Embodiment 1: the preparation method of microbial straw starter to produce straw protein feed

[0025] The method includes the following steps:

[0026] (a), using yeast, mold, bacillus, lactic acid bacteria, basidiomycete as provenance;

[0027] (b), slant strains: using wort culture medium with a total sugar content of 15%, the inoculum size of the seed solution is 10%, at 30°C, cultured for 26 hours and then stored at a temperature of 4°C;

[0028] (c), test tube liquid strains and first-level liquid culture: use wort medium or starch hydrolysis and saccharification liquid with a total sugar content of 16%, inoculum size is 10%, and culture at 25°C for 30 hours or static culture 30 hours;

[0029] (d), secondary liquid culture: using a starch hydrolysis and saccharification liquid with a sugar content of 15%, and an inoculum size of 10%, at 26°C for 30 hours or static culture for 30 hours;

[0030] (e), liquid culture: using a starch hydrolysis and saccharificatio...

[0040] Embodiment 2: the preparation method of microbial straw starter to produce straw protein feed

[0041] The method includes the following steps:

[0042] (a), using yeast, mold, bacillus, lactic acid bacteria, basidiomycete as provenance;

[0043] (b), slant strains: using wort culture medium with a total sugar content of 14%, the inoculum size of the seed solution is 11%, at 26°C, cultured for 28 hours and then stored at a temperature of 4°C;

[0044] (c), test tube liquid strains and first-level liquid culture: use wort medium or starch hydrolysis and saccharification solution with a total sugar content of 18%, inoculum size is 18%, and culture for 40 hours or static culture at 30°C 40 hours;

[0045] (d), secondary liquid culture: using a starch hydrolysis and saccharification liquid with a sugar content of 18%, and an inoculum size of 12%, at 30°C for 38 hours or static culture for 38 hours;

[0046] (e), liquid culture: using a starch hydrolysis and saccharificatio...

Embodiment 3

[0056] Example 3: Composition and nutritional value of straw

[0057] 1. Composition and digestibility of straw

[0058] (1) The crude fiber content is very high, and the straw is mostly in the post-mature stage of the plant. At this time, the degree of lignification of the plant cells is very high, generally between 31% and 45%.

[0059] The main component of straw is fiber (Table 1, 2), which is mainly concentrated in cell wall, and the cell wall content accounts for more than 70%, which is composed of cellulose, hemicellulose and lignin; acid detergent fiber is composed of cellulose and lignin. Cellulose and hemicellulose can be hydrolyzed by cellulolytic bacteria in the rumen of cattle and sheep to generate volatile fatty acids, such as acetic acid, propionic acid, butyric acid, etc., which are absorbed by cattle and sheep as energy. Bacteria in the rumen cannot break down lignin. The cellulose, hemicellulose and lignin in the straw are closely combined, which affects th...

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...
