METHOD FOR PRODUCTION OF FODDER ADDITIVE FOR ANIMALS Russian patent published in 2013 - IPC A23K1/12 

FIELD: food industry.

SUBSTANCE: invention relates to farm industry, in particular, to technologies for vegetal raw material fodder additives production with fungal bio-conversion usage. The method for production of a fodder additive for animals 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 beet pulp. 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, %: beet pulp -15-20, sunflower husk - 75-77.5, yeast extract - 0.3-0.4, 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 mass for 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 fodder additive.
