Technology: More than 13,000 calving sensors sold

Moocall has announced a multi-million dollar contract with Animal Health International (AHI), a leading US distributor.

The company markets the Moocall sensor, which is clipped onto a cow’s tail, and sends the herdowner a text about one hour before she calves.

Fitted with a rechargeable battery, it’s designed to work outdoors or indoors, and the relatively inexpensive sensor can be easily transferred from cow to cow.
