METHOD OF PRODUCTION OF FEED ADDITIVE FROM PLANT RAW MATERIAL FOR POULTRY Russian patent published in 2013 - IPC A23K1/16 A23K1/14 

FIELD: agriculture.

SUBSTANCE: invention relates to animal breeding, in particular to the technology of production of feed. The method of production of feed additive comprises stirring of the pretreated cellulose-containing raw material with nutritional additives, the introduction of microorganisms, exposure and the subsequent treatment. The sunflower husk and rice screenings are used as the cellulose-containing raw material. The pretreatment of the cellulose-containing raw material is performed by extrusion at the temperature 110-130°C. The resulting extrudate is milled with the subsequent stirring for 5-10 minutes and adding of nutritional supplements into it in the form of yeast extract and the suspension of chlorella. The microorganisms Trichoderma viride of strain F-98 in an amount of 1-2% by weight of the mixture is added to the resulting mixture and exposed for 6-7 days at the temperature 26-30°C with intermittent stirring. The resulting wet mixture is dried to a moisture content of 10-12% at the temperature 40-50°C and milled.

EFFECT: intensification of destruction of cellulose-lignin complex of raw material is provided due to more complete hydrolysis, and increase of feed nutrient density, increased protein content in it, preservation of vitamins, elimination of harmful microorganisms, and enrichment with cellulose-digesting enzymes.
