Abstract

The invention discloses a method for producing microbial fermentation corn germ meal. The method comprises the following steps: by taking corn germ meal as a main raw material, adding microbial compound bacteria liquor (saccharomycetes, lactic acid bacteria and bacillus subtilis) and sterile water according to a certain ratio, uniformly stirring, packaging in a plastic bag, closing and standing for fermenting for 72 hours. The fermented fresh material is strong in aroma sauce, enriched in viable bacteria and metabolic products, high in feed conversion rate and fast in animal breeding growth speed. The material contains the moisture content being less than or equal to 12 percent, only needs to be crushed and added, is convenient to use and storage-resistant, has the quality guarantee period being over 12 months and is a novel fermented feed raw material aiming at animal breeding development.

Description

technical field [0001] The invention relates to the field of animal breeding. Background technique [0002] Corn germ meal (corn germ meaL-so1) is a by-product obtained by pressing or leaching oil from corn germ as raw material. Also known as corn navel meal. Generally, before cornstarch is produced, corn is soaked, crushed, and the germ is separated, and then the oil is extracted. The oil extraction process is divided into dry method and wet method, and corn germ meal is obtained after oil extraction. Since corn germ meal contains more fiber, lower crude protein content, and slightly sour smell, the palatability is reduced. Animal breeding is limited, resulting in corn germ meal can not be well utilized in feed, in view of this situation, the present invention, after studying the characteristics of corn germ meal, starting from green, environmental protection, nutrition, energy saving, using Microbial fermentation technology improves the quality of corn germ meal and ...
