A system for managing the supply of consumable matter to be consumed by milk producing animals, the system comprising: a supply arrangement (24, 26, 28, 34, 36, 38) for supplying consumable matter to a feeding trough from which the animal can eat and/or drink, a control unit which controls the supply of the consumable matter to the feeding trough, an analysis device adapted to automatically analyse the milk from an individual milked animal with regard to at least one property of said milk, wherein the control unit is arranged to receive information from the analysis device, characterized in that said analysis device is adapted to sense at least one property of the milk with help of which it can be determined whether the animal, clinically or sub-clinically, is likely to suffer from ketosis, and/or said analysis device is adapted to sense at least one property of the milk with help of which it can be determined whether the animal, clinically or sub-clinically, is likely to suffer from milk fever, wherein the control unit is adapted to automatically control the composition of the consumable matter supplied to the feeding trough in dependence on the information received from the analysis device, wherein the supply arrangement (24, 26, 28, 34, 36, 38) comprises a first matter supply means (24, 26, 28) for supplying consumable matter to a feeding trough at a certain feeding position (10, 16), wherein the supply arrangement (24, 26, 28, 34, 36, 38) also comprises an additional matter supply means (34, 36, 38) for supplying consumable matter of a different composition, than that supplied by the first matter supply means (24, 26, 28), to that feeding trough, wherein the control unit is adapted to automatically control the composition of the consumable matter by controlling the supply of consumable matter via said first (24, 26, 28) and additional (34, 36, 38) matter supply means. a supply arrangement (24, 26, 28, 34, 36, 38) for supplying consumable matter to a feeding trough from which the animal can eat and/or drink, a control unit which controls the supply of the consumable matter to the feeding trough, an analysis device adapted to automatically analyse the milk from an individual milked animal with regard to at least one property of said milk, wherein the control unit is arranged to receive information from the analysis device, characterized in that said analysis device is adapted to sense at least one property of the milk with help of which it can be determined whether the animal, clinically or sub-clinically, is likely to suffer from ketosis, and/or said analysis device is adapted to sense at least one property of the milk with help of which it can be determined whether the animal, clinically or sub-clinically, is likely to suffer from milk fever, wherein the control unit is adapted to automatically control the composition of the consumable matter supplied to the feeding trough in dependence on the information received from the analysis device, wherein the supply arrangement (24, 26, 28, 34, 36, 38) comprises a first matter supply means (24, 26, 28) for supplying consumable matter to a feeding trough at a certain feeding position (10, 16), wherein the supply arrangement (24, 26, 28, 34, 36, 38) also comprises an additional matter supply means (34, 36, 38) for supplying consumable matter of a different composition, than that supplied by the first matter supply means (24, 26, 28), to that feeding trough, wherein the control unit is adapted to automatically control the composition of the consumable matter by controlling the supply of consumable matter via said first (24, 26, 28) and additional (34, 36, 38) matter supply means.
