FIELD: veterinary medicine.

SUBSTANCE: device comprises the starting and working compartments equipped with feeders for feeding liquid food. The means of automated feeding food comprise a computer, a capacitive sensor, a pulse shaper and a solenoid. The means of automated registration comprise infrared and strain-gauge sensors, a bridge circuit, a multi-channel amplifier, and a recorder. The feeders are made in the form of bars with recesses for food. The feeder is equipped with removable inserts comprising feed recesses of smaller sizes. The recesses of the feeder are equipped with removable inserts that imitate the type and amount of feed placed in the recesses. In the starting and working compartments the infrared sensors are mounted, the capacitive sensor is placed in the central recess, and the strain-gauge sensors are placed in the recesses of the feeders. The sensors are connected in series with a multi-channel amplifier and the recorder providing registration of time of running to the feeders and the amount of feed that is fed and eaten. The computer by means of the automated feeding food provides changing the amount of the feed supplied and the time intervals between meals fed separately.
