Trevor Hooker milks 400 cows in a 26 swing-over herringbone dairy in Inverloch, Gippsland, Victoria. In July 2025, he replaced manual teat spraying with an automated walkover teat sprayer.
His search for a better teat spraying system began with one goal: more efficient milking.
On the farm where Trevor share farms near Inverloch, teat spraying was a manual milking task. To speed up milking, he researched automatic teat spraying systems online, then contacted his local GEA dealer.
What he wanted was straightforward: a walkover teat sprayer he could rely on.
He chose the GEA iSPRAY-VISION walkover teat sprayer.
The system was installed two months later. Trevor says installation took about a day and a half, and the system quickly became part of daily milking.
“It’s been set and forget.”
From manual teat spraying to automation
Before installing GEA iSPRAY-VISION, teat spraying required someone to manually walk down the pit with a spray hose once cows had finished milking.
It was another job that needed to be completed consistently, every milking.
With iSPRAY-VISION, that manual step has been removed from Trevor’s routine.
“Now we don’t do that anymore. iSPRAY-VISION has certainly saved a lot of time in that way.”
For Trevor, the benefits extend beyond simply removing the manual spraying job.
He says the change has helped reduce the time spent in the dairy and contributed to a cleaner milking environment. Trevor also identifies better teat condition and reduced teat spray use among the most valuable changes he has observed on farm.
Saving teat spray as well as time
One of the benefits Trevor has particularly noticed is reduced teat spray use.
Because iSPRAY-VISION automatically detects cows moving through the exit and applies teat spray as they pass through, Trevor is no longer relying on himself or his staff to manually apply product cow by cow.
He has noticed savings in both time and teat spray product.
“What I really love about iSPRAY-VISION is it’s saving a lot of time. It’s saved me product.”
For a working dairy farm, those everyday efficiencies matter.
Less time performing a manual task helps keep the milking routine moving, while automatic teat spraying reduces the variation that can occur when different people are responsible for the job.
Better teat condition observed on Trevor’s cows
Trevor says the herd had consistently maintained a cell count of 135000 - 150000. Since installing iSPRAY-VISION, he has recorded cell counts consistently around 110000 – 130000.
While cell count is influenced by a range of herd and farm-management factors, Trevor has also observed better teat condition since installing the system.
These results come from AI-driven camera technology that tracks cows in real time to locate the udder, combined with a robust four-nozzle design for full teat spray coverage. Since its release, iSPRAY-VISION has delivered accurate, consistent application across a range of herds.
Who would Trevor recommend iSPRAY-VISION to?
After using the system on his own farm, Trevor sees clear applications for other Australian dairy farmers.
His advice is particularly relevant for farms wanting to speed up milking, improve teat condition or reduce the variation that can occur when staff are responsible for manual teat spraying.
“I reckon iSPRAY-VISION is ideal for anyone that’s looking to speed up milking and improve teat condition. If you’ve got workers that maybe aren’t spraying the teats properly, this certainly does.”
