METHOD FOR PRODUCTION OF ANIMALS FODDER ADDITIVE WITH CELLULOLYTIC ACTIVITY Russian patent published in 2013 - IPC A23K1/16 A23K1/14 

FIELD: food industry.

SUBSTANCE: invention relates to farm industry, in particular, to technology for production of vegetal raw material fodder additives. 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 yeast autolysate. Then microorganisms of F-98 Trichoderma viride strains are introduced into the produced mixture in an amount of 1-2% of the mixture weight and 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 celluloselignine 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.
