Problems solved by technology

For the method of crushing, adding water, stirring and direct feeding, the absorption rate of nutrients to animals is extremely low. Although the ammoniated straw improves the absorption rate of feed, it is not suitable for large-scale industrial production due to the limitations of its product characteristics and production methods.
CN101720850A discloses a biological straw feed. Although the fermentation method improves the nutritional value of the straw to a certain extent, it still cannot solve the storage and transportation problems of the straw feed
CN102132762A discloses a straw feed and its preparation method, the method adopts two-step aerobic and one-step anaerobic fermentation, complicated operation and long fermentation time

Abstract

The invention provides a method for producing probiotic bacteria granular feed by fermenting corn straw with mixed strain. The method comprises the steps of pulverizing newly harvested and dried corn straw to 1-5 mm; adding bran, corn flour and water, wherein mass contents of the bran, the corn flour and water are 2-5%, 3-6% and 60% of total weight of prepared feed respectively, and mixing; high-pressure sterilizing to obtain fermentation culture medium; inoculating Aspergillus niger, brewing yeast and Bacillus natto; performing mixed fermentation; adding corn flour and water, wherein mass contents of the corn flour and water are 18-25% and 20-30% of total weight of prepared feed respectively, and fully mixing; setting working parameters of a cold granulating machine as: mold hole diameter of 4-6 mm, and distance between a cutter blade and a mold plate of 20-30 mm; and granulating. The granular feed has the advantages of low cost, simple preparation, high probiotic bacteria content, and rich nutrients; can effectively improve animal immunity, reduce disease occurrence, and improve quality of livestock and poultry products.

Description

technical field [0001] The invention relates to a method for producing feed, in particular to a method for producing probiotic granule feed by fermenting corn stalks with mixed bacteria. Background technique [0002] Corn stalks contain more than 30% carbohydrates, 2% to 5% protein and 0.5% to 1% fat. They are high-quality raw materials for the production of feed. However, the utilization rate of corn stalks is extremely low at present, and most of them are randomly Discarding or even burning will not only cause environmental pollution but also cause a large waste of resources. The traditional methods of using corn stalks to feed animals mainly include the method of crushing and adding water to stir and feed directly and the method of ammoniation treatment. For the method of crushing, adding water and stirring for direct feeding, the absorption rate of nutrients to animals is extremely low. Although the ammoniated straw improves the absorption rate of feed, it is not suitab...
