The two milk tanks are configured to receive a stored full milk quantity and the drawing line comprises two drawing line portions each comprising a drain valve and each connected to one of the two milk tanks. A preparing unit is configured to prepare a liquid ration and a connecting line configured to connect the drawing line with the preparing unit. a cleaning unit comprises at least one cleaning agent container configured to receive a cleaning agent, and a cleaning agent supply apparatus configured to supply cleaning agent from the cleaning agent container to the two milk tanks. A control is configured to actuate the cleaning unit, the preparing unit, and each drain valve to guide the cleaning agent guided from one of the two milk tanks through the connecting line into the preparing unit. ## Claims ### Claim at position 1 1-15. (canceled) ### Claim 16 A system for feeding farm animals with a liquid containing full milk, the system comprising: a full milk depot comprising two milk tanks and a drawing line, wherein the two milk tanks are configured to receive a stored full milk quantity, and wherein the drawing line comprises two drawing line portions each comprising a drain valve and each connected to one of the two milk tanks; a preparing unit configured to prepare a liquid ration, wherein the preparing unit comprises, a milk supply line, a liquid ration container, and a tap line; a connecting line configured to connect the drawing line with the milk supply line; a sucking dummy connected to the tap line; a cleaning unit comprising, at least one cleaning agent container configured to receive a cleaning agent, and a cleaning agent supply apparatus configured to supply cleaning agent from the cleaning agent container to the two milk tanks; and a control configured to actuate the cleaning unit, the preparing unit, and each drain valve to guide the cleaning agent guided from one of the two milk tanks through the connecting line into the preparing unit. ### Claim 17 (depends on 16) The system according to claim 16, wherein: the sucking dummy is connected to the tap line via a sucking line; a branching line branches off from the sucking line at a branching point; and a pump is located in the branching line. ### Claim 18 (depends on 17) The system according to claim 17, wherein during a cleaning operation, the control is configured to actuate the preparing unit and the pump to guide the cleaning agent from the milk supply line through the liquid ration container, through the tap line, through the sucking line to the branching point and then through the branching line. ### Claim 19 (depends on 16) The system according to claim 16, further comprising at least one of a fill level sensor and an empty level indicator positioned in the drawing line. ### Claim 20 (depends on 16) The system according to claim 16, wherein the cleaning unit further comprises a water connection and a cleaning line, wherein the cleaning line leads from the water connection to the two milk tanks, and wherein the cleaning agent supply apparatus comprises a pump configured to pump cleaning agent from the at least one cleaning agent container into the two milk tanks and the cleaning line. ### Claim 21 (depends on 20) The system according to claim 20, wherein the cleaning line is connected to spraying nozzles arranged in the two milk tanks. ### Claim 22 (depends on 16) The system according to claim 16, further comprising a first circulation line including a circulation pump and configured to connect the drawing line to the two milk tanks, wherein the circulation pump is configured to guide cleaning fluid back into the two milk tanks. ### Claim 23 (depends on 16) The system according to claim 16, wherein the full milk depot further comprises at least one of: (1) a heating apparatus; (2) a cooling apparatus; (3) a thermal insulation; and (4) a stirrer. ### Claim 24 (depends on 16) The system according to claim 16, further comprising a heating apparatus configured to heat milk located in one of the two milk tanks to a pasteurization temperature and further configured to hold the milk at the pasteurization temperature for a specified period of time. ### Claim 25 (depends on 16) The system according to claim 16, wherein the control is configured to automatically perform a cleaning operation based on a programmed schedule, and wherein the control is configured to: forecast demand for one of the two milk tanks which is empty at a first cleaning time; specify a filling quantity that will satisfy the forecasted demand until a second cleaning time which follows the first cleaning time; and specify a filling time such that, when the one of the two milk tanks is filled, a stored full milk quantity is available in the one of the two milk tanks before a second of the two milk tanks is empty. ### Claim 26 (depends on 25) The system according to claim 25, wherein the control is configured such that, when the filling lime is specified, a time required for pasteurization of the full milk is taken into account, and wherein the pasteurization can take place either in one of (1) the two milk tanks, and (2) in an external pasteurization apparatus. ### Claim 27 (depends on 17) The system according to claim 17, further comprising a cleaning line configured to transition into two cleaning line portions at the branching point, wherein each of the two cleaning line portions leads to one of the two milk tanks, and wherein each of the two cleaning line portions comprises a shut-off valve. ### Claim 28 (depends on 16) The system according to claim 16, further comprising a full milk pump and a heating apparatus positioned in the milk supply line and configured to heat a fluid moved through the milk supply line to a desired temperature before filling the liquid ration container. ### Claim 29 (depends on 25) The system according to claim 25, wherein the control comprises a notification unit configured to inform a user of a status of the system. ### Claim 30 (depends on 29) The system according to claim 29, wherein the control further comprises a documentation unit configured to document the cleaning operation. ### Claim 31 (depends on 16) The system according to claim 16, wherein the cleaning agent supply apparatus comprises a cleaning agent line configured to supply cleaning agent from the at least one cleaning agent container to the preparing unit while circumnavigating the full milk depot, and wherein the control is configured to automatically perform a cleaning of the preparing unit based on a specified schedule separate from a cleaning of the full milk depot.
