Research result of  process of electrochemical oxidation of rough plant raw materials: the mathematical planning of experiments, the researches, the creation of mathematical models. Authors defined optimum conditions of processing: temperature of the electrolyte is 70 degrees, the pH of electrolyte - treatment of rye straw and birch sawdust at pH equal 8,0–10,0 (25% of electricity), then at pH equal 4,0–6,0 (75% of electricity ), aspen sawdust at pH = 4,0–6,0, the anode density of current is 0,125 kA/m2, the initial concentration of sodium chloride is 30,0 kg/m3 of electrolyte, quantity of electricity is 0,9 kA·h/kg of raw materials. After the electrochemical treatment of rye straw, birch and aspen sawdust, are identified reducing substances (6,0–6,3 wt.% of the raw materials), glucose (4,5–5,0 wt.% of the raw materials), oxygen-containing compounds of chlorine (ClO- of less than 0,001 kg/m3 electrolyte, ClO3- is 0,014–0,019 kg/m3 electrolyte), the mass of the residual solid (60–80 wt.% of raw material), ruthenium and titanium (the absence). The method is planned for using in a forage production on purpose of eliminate the imbalance of sugars in a fodder diet of agricultural animals.
