A system for managing the supply of consumable matter to be consumed by milk producing animals includes a supply arrangement (24, 26, 28, 34, 36, 38) for supplying consumable matter to a feeding trough (14) from which the animal (12) can eat and/or drink, and a control unit (30) which controls the supply of the consumable matter to the feeding trough (14). The system also has an analysis device (40) adapted to analyse the milk from an individual milked animal (12) with regard to at least one property of the milk. The control unit (30) is arranged to receive information from the analysis device (40) and to automatically control the composition of the consumable matter supplied to the feeding trough (14) in dependence on the information received from the analysis device (40).
