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

FIELD: food industry.

SUBSTANCE: invention relates to cattle breeding, in particular, to technologies for vegetal raw material fodders production with bioconversion usage. The vegetal raw material 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 offal. 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 nutritional additives in the form of yeast extract and a chlorella suspension. The initial components are taken at the following ratio, wt %: offal - 25-30, sunflower husks - 65-67.5, yeast extract - 0.3-0.4, chlorella suspension - balance. Then microorganisms of F-98 Trichoderma viride strains are in introduced into the mixture in an amount of 1-2% of the mixture weight and maintained during 6-7 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 usage will allow to enhance nutritional value and protein content in the additive as well as preserve vitamins.
