Disclosed is a method for determining a likelihood for a state of a cattle animal. The method comprises capturing (S100), by a thermal imager, a plurality of images of a cattle animal, analyzing (S105) a thermal characteristic of the images, and determining (S110), based on the plurality of images, a movement pattern of the cattle animal. The method further comprises comparing (S120) the determined movement pattern with a reference movement pattern and then determining (S130), based on the comparison, if the detected movement pattern correlates with a known state out of a plurality of known states, the plurality of known states including at least oestrus, pregnancy and parturition. The method further comprises outputting (S140), based on the determining, a likelihood value for at least one of the plurality of known states.
