METHOD FOR PRODUCTION OF FODDER ADDITIVE WITH RICE SCREENINGS FOR BIRDS Russian patent published in 2014 - IPC A23K1/16 A23K1/14 

FIELD: food industry.

SUBSTANCE: invention relates to farm industry, in particular, to the technologies for fodders production from farm industry by-products and to processing industry with filamentous fungi usage. The fodder additive production method involves stirring of preliminarily treated cellulose-containing raw materials with nutritional additives, microorganisms introduction, maintenance and subsequent treatment. The cellulose-containing raw materials are represented by sunflower husks and rice flour. Preliminary treatment of the cellulose-containing raw materials is performed by way of extrusion at a temperature of 110-130°C. The produced extrudate is milled with subsequent 5-10 minutes' stirring and introduction of water and a nutritional additive in the form of beer wort. All the initial components are taken at the specified ratio. Then microorganisms of F-83 8 Trichoderma viride strains are introduced into the produced mixture in an amount of 1-2% of the mixture weight and maintains the mass for 6-8 days at a temperature of 26-30°C with periodic stirring. The produced wet mixture is dried till moisture content is equal to 10-12% at a temperature of 40-50°C and is milled.

EFFECT: invention implementation ensures intensification of destruction of the cellulose-lignine complex of the initial raw materials due to more complete hydrolysis and the fodder nutritional value increase, protein content increase in the fodder, vitamins preservation, harmful microorganisms elimination and the fodder enrichment with cellulose-digesting enzymes.
