Problems solved by technology

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 suitable for large-scale industrial production due to its product characteristics and production methods.

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 method of the present invention involves the method of production of feed. Specifically, it is a method for the production of probiotic granules for mixed bacteria fermented corn straw. Background technique [0002] Corn straw contains more than 30 % carbohydrates, 2 % to 5 % protein, and 0.5 % to 1 % fat. It is a high -quality raw material for production of feed. However, the current utilization rate of corn straw is extremely low.Discarding or even incineration not only causes environmental pollution, but also causes a lot of waste of resources.The traditional methods of using corn straw feeding animals are: the method of adding water and stirring to directly feed and the method of ammonia treatment.In response to the method of crushing and mixing and stirring, the absorption rate of animals on nutrients is extremely low. Although the straw treated straw increases the feed absorption rate, the limited product characteristics and production methods are...
