METHOD FOR PREPARATION OF FODDERS OF RAW MATERIALS WITH HIGH CONTENT OF LIGNIFIED CELLULOSE Russian patent published in 2015 - IPC A23K1/12 A23K1/00 

FIELD: food industry.

SUBSTANCE: invention relates to the field of farm industry and fodder production. The method for fodder preparation involves raw materials milling, mineral additives introduction into the raw materials and enzymic bacterial hydrolysis with introduction of an enzymic bacterial starter consisting of ruminant animals paunch contents. Before enzymic bacterial hydrolysis one performs delignisation of cellulose contained in the raw materials with simultaneous enrichment of the raw materials with mineral substances by way of the raw materials wetting with plant ash and soda based alkaline solution. The produced mass is maintained till a softened condition and dark- straw coloration and acidified till pH is equal to 4.5-6.0 with IB-2 preserving agent solution. Through addition of cellulolytic enzymes, the mass moisture content is conditioned to 60-65%, temperature - to 50-55° C; the mass is compressed and stored in an air tight condition till temperature is decreased to 38-45° C. Then one adds suspension of the enzymic bacterial starter enriched with cellulolytic enzymes and lactic acid bacteria wherein ammonium chloride is dissolved as an ammonium additive. The produced fodder is stored under anaerobic conditions. The fodder ventilation is performed during the fodder collection, transporting and dispensing to animals.

EFFECT: invention implementation ensures the fodder quality enhancement with simultaneous simplification of the fodder production technology.
