METHOD OF PRODUCTION OF FEED ADDITIVE WITH CELLULOLYTIC ACTIVITY FOR POULTRY BREEDING Russian patent published in 2013 - IPC A23K1/16 A23K1/00 A23K1/14 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to the technology of production of feed from by-products of agriculture and processing industry. The method of production of feed additive with cellulolytic activity for poultry breeding comprises stirring of the pretreated cellulose-containing material with nutritional additives, the introduction of microorganisms, exposure and the subsequent treatment. The sunflower husk and brewer pellet 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 water and nutritional supplement into it in the form of yeast autolysate. The microorganisms Trichoderma viride of strain F-838 in an amount of 1-2% by weight of the mixture is added to the resulting mixture and exposed for 6-8 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.
