Gallagher, famous for its electric fence technology is moving into  a new frontier – virtual fencing. The Waikato company has taken over virtual fence company Agersens, the Australian company who created eShepherd. Virtual fencing system uses GPS-connected collars fitted around a cattle beast’s neck and uses audio cues and pulses to direct the animal. Gallagher first began investing in eShepherd in 2016 and moved to full ownership earlier this month. Gallagher chief executive Kahl Betham says the eShepherd technology is a critical component of future farming  which adds animal monitoring and also automated pasture management. He says eShepherd means farmers can manage every animal as an individual, providing a quantum lift in productivity, monitoring its location and controlling its movement. The collar is connected online by a base station and  alerts farmers if an animal is behaving abnormally.
