PRODUCTIVE ANIMALS FODDER ADDITIVE PRODUCTION METHOD Russian patent published in 2013 - IPC A23K1/16 A23K1/14 

FIELD: food industry.

SUBSTANCE: invention relates to farm industry, in particular, to technology for vegetal raw material fodder additives production with bioconversion 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 beet pulp. 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 corn-steep extract. Then microorganisms of F-838 Trichoderma viride strains are introduced into the produced mixture in an amount of 1-2% of the mixture weight and the mixture is maintained during 6-8 days at a temperature of 26-30°C with periodical 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 raw materials due to more complete hydrolysis and the fodder nutritional value increase, protein content increase, vitamins preservation, harmful microorganisms elimination and enrichment with cellulose-digesting enzymes.
