FIELD: agriculture.
SUBSTANCE: invention relates to agriculture. The device contains setting device of actual age of livestock (1), block of setting devices of intermediate control signals (2), block of setting devices of economically optimal food doses (3), its outputs are connected to the appropriate first non-inverting inputs of the block of comparison circuit of food dose signals (4), to its second appropriate inverting inputs the outputs of the block of setting devices of actual food doses (5) are connected, and outputs of the block of comparison circuits of food dose signals (4) are connected with the appropriate inputs of the block of food dosing units (6), its outputs are connected with inputs of the mixer (7), at its output the economically optimal food mixture is prepared (8). The device has setting device of simulated signal of livestock age (9), setting device of simulated signal of food mixture dose upon maximum growth of live weight of the live stock (10), setting device of simulated signal of food mixture dose upon minimum growth of live weight of the live stock (11), calculator of signal of live weight of the live stock at the initial stage of culture (12), calculator of signal of economically optimal ration during the initial stage of culture (13), calculator of signal of live weight of the livestock at final stage of culture (14), calculator of signal of economically optimal ration during the final stage of culture (15), comparison circuit of signals of live weight of the livestock during initial and final stages of culture (16), signal generator to deactivate mode of calculation of maximum growth of live weight and switching to mode of calculation of minimum growth of live weight (17), block of controlled keys (18), signals matching circuit (19), block of control signal generators or interface of the person making the decisions (20), setting device of signal of type of the optimisation criterion (21), meter of signal of live weight of the animal or bird (22), setting device of signal of design dose of the food mixture (23), block of setting devices of signals of function coefficients of losses of design productiveness of the animal or bird (24), setting device of signal of permitted criterion decreasing (25).
EFFECT: automatic control of the processes is ensured, increased accuracy of determination of food doses in the food mixture.
