METHOD FOR PRODUCTION OF FODDER ADDITIVE WITH FERMENTATIVE PROPERTIES FOR POULTRY FARMING Russian patent published in 2013 - IPC A23K1/12 

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 fungal bio-conversion usage. The method for production of a fodder additive with fermentative properties for poultry farming 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 brewer grains. 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 extract into the extrudate; the initial components are taken at the following weight ratio, %: brewer grains 10-15, sunflower husk - 80-82.5, yeast extract - 0.2-0.4, water - balance. Then into the produced mixture one introduces Trichoderma viride microorganisms of strain F-98 in an amount of 1-2% of the mixture weight and maintains the during 6-7 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 usage will allow to increase nutritive value and protein content as well as preserve vitamins in the additive.
