Ear-tag/app combination to help farmers manage cattle rotation

Fencing required for rotational grazing often comes at a high cost for cattle farmers.

Rotational grazing improves pasture production, increases carbon sequestration and means more animals can be kept on the same plot. This cattle ear tag integrates bluetooth, GPS, and speakers helping farmers manage their cattle with virtual fences. Heard’s app stores health history and information for each specific cow allowing them to be monitored and moved when necessary.
