A device that sends text messages to a farmer when a cow is about to give birth is now available in New Zealand.
The Moocall is a palm-sized monitor that is attached to a pregnant cow.
Using motion technology, the sensor picks up heightened tail movement - indicating a cow is due to give birth shortly - and sends a text message to its owner.
An example of a message would be: "Unit 1: High cow activity last 1 hour."
The sensors went on the market last December, but have just been made available in New Zealand and Australia.
