<p>A system (11) is provided for estimating the solid feed consumption by animals on a farm on an animal individual level, wherein the solid feed comprises sodium and/or potassium and the animals are allowed to drink water only at one or more water supply positions (12, 13, 14). At each of the water supply positions and each time an animal is present at the water supply position, an animal identifying device (12a, 13a, 14a) is configured to identify the animal present at the water supply position and a water amount measuring device (12b, 13b, 14b) is configured to measure the amount of water the animal identified at the water supply position drinks; and a processing device (15) is operatively connected to the animal identifying devices and the water amount measuring devices to obtain, for each of the identifications, the identity of the animal and the measured amount of water drunk by the animal. The processing device is configured to receive a value of the content of sodium and/or potassium in the solid feed and, for each of the animals, estimate the solid feed consumption of the animal based on the measured amounts of water drunk by the animal together with the received value of the content of sodium and/or potassium in the solid feed.</p> |
