This paper presents the result of study of the automatic dosing system for fodder elements in industrial conditions. A process of dosing the chosen raw materials of fodder mixture for cattle was analyzed for: maize, rape meal, wheat and triticale. Data was obtained for 8 succeeding cycles of dosing. A correctness of the work of the system was defined on the basis of the information about set mass (prescription) and obtained (real). The residual sum of squares proving the difference between obtained and set mass was the parameter that determines the largeness of deviation of real mass. Obtained results point at fluctuation of obtained mass of the given element in following cycles of dosing. The biggest deviation from the prescription mass was observed for rape meal. The results of the statistical test (test Mann-Whitney) didn't point at significance of the differences of dosing of chosen elements.
