V300 robots debut in Karaka
A small organic farm in South Auckland has become the first NZ recipient of DeLaval’s new robotic milking system, the VMSTM V300.
Fifty years is a long time to work in one industry, and long enough to witness lots of change.
Just so for Kim McKean, manager of the University of Sydney’s dairy operation at Camden, New South Wales who recently received the Dairy Science Award from the Dairy Research Foundation in recognition of his service to the industry.
He started as an animal attendant in 1966 and over the decades has trained thousands of veterinary and animal science students in practical animal husbandry, and been on-the-ground support for at least 100 masters and PhD students.
Now he helps oversee the implementation of the university’s Corstorphine farm robotic rotary dairy.
“When I started we were milking in a little six bail walk-through dairy, putting the cups on the cows and washing their teats with an old cloth,” he said. “I never thought I’d see robots milking the bloody things; it’s amazing.”
The university campus has five farms over 350ha and milks 360-380 cows.
In August last year, the farm transitioned from a 40-a-side double up herringbone system to the automatic milking system developed by the university in partnership with Swedish company DeLaval, the NSW Department of Primary Industries and Dairy Australia.
The robotic rotary has an internal, rotary herringbone platform, with cows facing outwards and the robots housed in the centre.
The system does teat washing and drying, applies the milking cups, removes cups, disinfects the teats and flushes the cups. It also monitors milk yield and quality.
Commercial versions can handle 90 cows per hour depending on the number of robots installed and the daily operational procedure. The dairy can do 1500-1600 milkings per day, meaning the equipment could milk up to 800 cows twice a day.
McKean said it had been a steep learning curve since they first started using the system in August. “I’m not particularly computer literate, though I am now apparently. It’s been a challenging 12 months, but we’ve got it going and it’s working well.”
The cows had settled into the new way of milking within a couple of days but they took longer to adjust to the voluntary cow traffic.
“I’ve always known animals are not stupid but this has reinforced just how smart they are. It only takes a couple of days for them to work out the new system. And from an animal welfare and cow comfort point of view the system is fantastic, because the cows move to the milking system voluntarily.”
The cows’ movements and eating patterns are monitored and tracked, and they are guided through designated gated areas to the milking area, knowing there is more food once they are milked.
“They love it. There’s no pressure on the cows, there’s no one yelling at them, they are not being jammed up in yards with lots of other cows. It’s good from that point of view.”
McKean said his biggest challenge adapting to the new technology was surrendering management to the system and trusting it to do the job.
“And someone has to be available to monitor the system, not necessarily be in the dairy, but be available to take automated phone calls from the system and to attend to an issue.”
That may mean a phone notification in the middle of the night to attend to a problem. “But the upside is, we start at 6am now and not 3.30am.”
He said 90% of the herd came to be milked during the night.
“We only get about 50-60% during the day and that’s because we do a lot of teaching of vet students here. It’s not the most appealing place to come (as a cow) when there is a high risk that you will be poked and prodded by a heap of students.”
McKean said adjusting to the robotic system had so far not made his life easier, but he can see it will as they get better at using it. “It’s definitely the way of the future.”
A brilliant result and great news for growers and regional economies. That's how horticulture sector leaders are describing the news that sector exports for the year ended June 30 will reach $8.4 billion - an increase of 19% on last year and is forecast to hit close to $10 billion in 2029.
Funding is proving crucial for predator control despite a broken model reliant on the goodwill of volunteers.
