METHOD FOR PRODUCTION OF 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 technologies for vegetal raw material fodders production with bio-conversion usage. The method for production of a fodder additive with cellulolytic activity involves stirring of preliminarily treated cellulose-containing raw materials with nutritive additives, microorganisms addition, the mixture maintenance and subsequent treatment. The cellulose-containing raw materials are represented by sunflower husk and offal. Preliminarily 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 minute stirring and introduction of water and a nutritive additive in the form of yeast autolysate into the extrudate. Into the produced mixture one introduces Trichoderma viride F-98 microorganism of strain F-98 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 milled.

EFFECT: invention implementation ensures cellulose-lignin complex destruction intensification and more complete hydrolysis of the raw materials, the fodder additive nutrition value enhancement, protein content increase, vitamins preservation, harmful microorganisms elimination and the fodder additive enrichment with cellulose- decomposing enzymes.
