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 organically combine, and Rapid Fermentation is digested into predigesting feed.Utilize the stronger enzymolysis of microorganism
Ability, partially or mostly resolves into feedstuff the small-molecule substance that animal directly absorbs, is more easy to after animal edible
Digestion and absorption；In addition the anti-nutritional factors to feedstuff and anaphylactogen degraded are obvious.No longer need to heat in preparation process
Device, without steam regulation of texture, conditioning of texture, directly mutually rubs fever, 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.Technique is simple, easy to high-activity biological feed
Mass production, granulation 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, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
