Livestock management system and method

A method of operating a tag attached to an animal comprising:

• obtaining, by a processor, information on a virtual fence defining a perimeter within which an animal is allowed to roam;
• acquiring, by the processor, animal location information on the animal from a location sensor;
• acquiring, by the processor, animal motion information on the animal from one or more motion sensors;
• operating the location sensor in a low power mode, during which the location sensor consumes at least less power from a battery compared to other times, wherein the location sensor is operated in a low power mode based at least in part on the animal motion information.
