Early Edition with Kate Hawkesby

A couple of students from Massey University have developed technology to help farmers monitor their cow's health. Their start-up Protag has developed small device clips that go onto a cow's ear, from there it transmits important data to farmers about the cow's health. They've raised $1m from investors to fast-track the development of the ear tag sensors. Co-founder of Protag Tyrel Glass joined Kate Hawkesby. LISTEN ABOVESee omnystudio.com/listener for privacy information.
