The preparation method of the cold granulation feed of present invention fermentation, it is while granulation, feed is former using the cold granulation device that ferments
Material and microbial concentration ferment albumen are organically combined, and Rapid Fermentation digests into predigesting feed.Using the stronger enzymolysis of microorganism
Ability, the small-molecule substance that animal directly absorbs partially or mostly is resolved into feedstuff, is more easy to after animal edible
Digestion and absorption；ANFs and anaphylactogen degraded in addition to feedstuff is obvious.Heating is no longer needed in preparation process
Device, without steam regulation of texture, conditioning of texture, directly mutually rubs heating, there is provided fermentation condition quickly realizes microorganism increasing by machinery and material
Value and macromolecular complex is changed into small-molecule substance, realizes feed predigestion function.Process is simple, is easy to high-activity biological feed
Mass production, pelletize it is best in quality.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications also should
It is considered as protection scope of the present invention.
