out food portion on an animal cage arranged ranged in a row of animal cages for fur animals by means of a motorized feed cart comprising wheels and a feed container, comprising the steps of: —moving said feed cart along a row of animal cages, —providing an output from an encoder corresponding to the angular turning of one of said wheels to a control unit, —determining that the feed cart has reached a given position corresponding to a given cage from said output and a database of information related to positions of animal cages and desired size of food portions to each animal cage, and —controlling the feed cart to metering out the desired food portions at a suitable food delivering place at the given animal cage according to the information in said database. ## Claims ### Claim 1 A method for positioning an individually metered out food portion on an animal cage arranged in a row of animal cages for fur animals, in particular mink, by means of a motorized feed cart comprising wheels, at least one driving wheel, and a feed container, said method comprises the steps of: moving said feed cart along a row of animal cages, thereby turning the wheels of the feed cart, providing an output from an encoder corresponding to the angular turning of one of said wheels to a control unit, determining by means of the control unit that the feed cart has reached a given position corresponding to a given cage from said output and a database of information related to at least positions of animal cages and desired size of food portions to each animal cage, and controlling the feed cart to metering out the desired food portions at a suitable food delivering place at the given animal cage according to the information in said database. ### Claim 2 (depends on 1) A method according to claim 1, wherein said determining by means of the control unit comprises the step of: adjusting an ideal relationship between the radius of the wheel on which said encoder measures angular turning and the distance travelled of the feed cart into an actual relationship on the basis of flattened tires due to the current weight of the feed cart with feed. ### Claim 3 (depends on 1) A method according to claim 1, wherein said feed container comprises an integrated weighing machine, which via communication equipment is connected with said control unit. ### Claim 4 (depends on 1) A method according to claim 1, wherein said encoder is mounted on a wheel of said feed cart, preferably a driving wheel. ### Claim 5 (depends on 1) A method according to claim 1, wherein said encoder is an optical encoder with a row of passages in a circular pattern, said encoder comprising at least one light source and at least one photo detector. ### Claim 6 (depends on 1) A method according to claim 1, wherein said optical encoder comprises at least two photo detectors and two concentric rows of passages, wherein said rows are slightly shifted in relation to each other in order for the signal from the encoder to reflect whether said feed cart runs forward or backwards. ### Claim 7 (depends on 1) A method according to claim 1, wherein said method further comprises an adjusting step for adjusting the recorded position of the feed cart in relation to the animal cages, wherein said adjusting step is carried out with a suitable light-emitter, such as a laser, and a suitable detector measuring the distance to known positions such as vertical bearing beams. ### Claim 8 (depends on 1) A method according to claim 1, further comprising the steps of: determining by means of the control unit and said database whether a medication should be provided at the given animal cage, and metering medication out according to the information in the database. ### Claim 9 (depends on 8) A method according to claim 8, wherein an outlet for the medication is provided at a food outlet of the feed card, so that said metered out medication is delivered together with the metered out food portion. ### Claim 10 (depends on 1) A method according to claim 1, wherein said feed cart is a motorized feed cart with movement controlled by a user, wherein said user controls said turning of the driving wheel. ### Claim 11 (depends on 1) A method according to claim 1, wherein said feed cart is an unmanned motorized feed cart, wherein said movement of the feed cart is carried out automatically by a control unit controlling said feed cart. ### Claim 12 (depends on 1) A motorized feed cart for performing the method according to claim 1, wherein said feed cart comprises wheels, at least one driving wheel, and a feed container, wherein a control unit is provided for determining the position of the feed cart and for metering out food, said control unit having access to a database of information related to at least positions of animal cages and desired size of food portions to each animal cage, and wherein said feed cart comprises at least one encoder capable of providing an output corresponding to the angular turning of one of said wheels to said control unit, wherein said control unit is adapted to determining the position of said feed cart on basis of said output. ### Claim 13 (depends on 12) A cart according to claim 12, wherein the database further comprises information relating to distribution of medication to at least a portion of animal cages, and wherein the control unit is provided for determining by means of the control unit and said database whether a medication should be provided at the given animal cage, and metering medication out according to the information in the database. ### Claim 14 (depends on 13) A cart according to claim 13, wherein an outlet for the medication is provided at a food outlet of the feed card, so that said metered out medication will be delivered together with the metered out food portion. ### Claim 15 (depends on 1) A system for performing the method according to claim 1 comprising a feed cart with an encoder, a control unit, a database, and fur animal houses or halls with fur animal cages arrayed so that a driveway is established along the fur animal cages or between the fur animal cages. ### Claim 16 A method for positioning an individually metered out food portion on an animal cage arranged in a row of animal cages for fur animals, in particular mink, by means of a motorized feed cart comprising wheels, at least one driving wheel, and a feed container, said method comprises the steps of: moving said feed cart along a row of animal cages, thereby turning the wheels of the feed cart, determining by means of the control unit that the feed cart has reached a given position corresponding to a given cage from said output and a database of information related to at least positions of animal cages and desired size of food portions to each animal cage, controlling the feed cart to metering out the desired food portions at a suitable food delivering place at the given animal cage according to the information in said database. determining by means of the control unit and said database whether a medication should be provided at the given animal cage, and metering medication out according to the information in the database. ### Claim 17 (depends on 16) A method according to claim 16, wherein an outlet for the medication is provided at a food outlet of the feed card, so that said metered out medication is delivered together with the metered out food portion. ### Claim 18 (depends on 2) A method according to claim 2, wherein said feed container comprises an integrated weighing machine, which via communication equipment is connected with said control unit. ### Claim 19 (depends on 4) A method according to claim 4, wherein said encoder is an optical encoder with a row of passages in a circular pattern, said encoder comprising at least one light source and at least one photo detector.
