Cow Collars Revolutionize Farming with Virtual Fences

New Zealand startup Halter has developed an innovative system using solar-powered collars to manage cattle herds through virtual fences. The technology, which gained significant backing from Founders Fund, enables farmers to remotely guide their livestock and monitor their health, including fertility cycles and signs of illness. This advancement allows for more efficient land use, potentially increasing productivity by as much as 20%.

Halter's solution involves a collar, a network of towers, and a smartphone app. Cattle are trained to respond to audio and vibration cues from the collar, learning to respect virtual boundaries within a few interactions. The system has been deployed on over a million cattle across more than 2,000 farms in New Zealand, Australia, and the United States.
