Weighing of Animals

A device for monitoring the weight of animals in an animal housing facility, the device comprising:

• a support surface configured so that at least one of the animals can stand on the support surface, in operation of the device;
• a force sensor, connected to the support surface, for measuring a force indicative of a weight of the animal or animals on the support surface, in operation of the device;
• a rail system actuator for suspending the device from a rail or track of a rail system and to propel the device when controlled accordingly, along the rail or track when operably attached thereto;
• and
• a processor,
• wherein the processor is adapted for:
• controlling the rail system actuator to move the actuator to a target position in the animal housing facility;
• receiving a signal from the force sensor indicative of a weight of the animal or animals on the support surface when the support surface is located at the target position;
• and
• determining a weight measurement of an individual animal based on the signal.
