Abstract

The invention discloses a preparation method of a moderately-dried solid microbial fermented livestock fodder. The preparation method of the moderately-dried solid microbial fermented livestock fodder provided by the invention comprises the following steps: drying a fodder directly prepared by solid microbial fermentation to enable the water content of the fodder to be 16%-22% so as to obtain the solid microbial fermented livestock fodder, wherein a fluidized drying mode is adopted preferably. The invention also discloses the solid microbial fermented livestock fodder produced according to the method. According to the method disclosed by the invention, the technological operation is simple, convenient and flexible, the equipment investment is low, and the produced solid microbial fermented livestock fodder can satisfy the requirements on market circulation time, also can adapt to changes of various storage environment conditions, and especially can adapt to the changes of seasons and site environments, so that the solid microbial fermented livestock fodder is suitable for popularization and application in the vast rural areas of China.

Description

Technical field [0001] The invention relates to a method for preparing livestock and poultry feed, in particular to a method for preparing moderately dry solid microbial fermentation livestock and poultry feed. Background technique [0002] In recent years, the production technology of industrialized large-scale solid-state fermentation of livestock and poultry biological feed has become increasingly mature, and more and more feed manufacturers can produce microbial fermented feed by themselves. Most of the production of microbial fermented feed involves the participation of lactic acid bacteria, and in many cases anaerobic lactic acid bacteria fermentation is the mainstay. The production process mainly includes thick-bed anaerobic fermentation (including large-pool anaerobic fermentation and large-tank anaerobic fermentation) and bag-type anaerobic fermentation. Except for the specific bagged air pressure self-balancing anaerobic fermentation, other forms of fermented feed usua...
