Special Episode - Halter: Driving Profit, Efficiency and Sustainability

This special episode of CountryWide explores the first independent evaluation of Halter’s virtual fencing and herding technology, now used on more than 600,000 dairy and beef cows across New Zealand, the United States and Australia. An AgFirst and Transform Agri study of ten high-performing dairy farms shows clear gains in pasture utilisation, labour efficiency, animal performance and environmental outcomes.
Sarah Perriam-Lampp speaks with James Allen from AgFirst, Julian Gaffney from Transform Agri and Halter’s Head of Corporate Farming, Steve Crowhurst, to unpack the findings, including an average 13 percent lift in farm profit before tax and how top operators are using the system.
