Got Robots? Oregon Dairies Embracing Automation
After serving three generations of the Mann family, the old milking parlor at the Abiqua Acres dairy farm had seen better days. So when Alan and Barbara Manns’ daughter Darleen Sichley and her husband, Ben, decided to join the family operation, it was time to upgrade.
And upgrade they did.
The Silverton, Oregon, dairy today is among a small, but growing number of Western U.S. dairies using robotic milking systems. The 95-cow Guernsey dairy installed two robotic milkers in January 2017.
“It was a tough decision,” said. “It is a big investment. But we had to look at going a different direction when my husband and I joined.”
Robotic milking systems are employed on less than two percent of U.S. dairies, said Kurt Mizee, president of Priority Robotics in Tillamook, Oregon, who, with his father, Bart Mizee operates Tilla-Bay Farms in Tillamook. But the technology is catching on rapidly among big and small dairies.
“The adoption is definitely ramping up,” said Mizee, who runs three robotic milkers on his fourth-generation Tillamook dairy, including two he installed in 2011, the first ever installed in the Western U.S.
Dairy farmers choose to go robotic for several reasons, Mizee said. Some, such as the owners of Abiqua Acres, chose robotics primarily for the scheduling flexibility the systems provide.
“When you’re milking cows, it’s always four o’clock in the morning and four in the afternoon,” Darleen Sichley said. “Now you can work around what you want to do. Things still have to get done that day, but it is not so time sensitive.”
She added: “My parents sacrificed a lot when they milked cows for twenty years. Looking at what direction we wanted to go, robotics felt like a really good fit; because there is that flexibility, that balance between dairying and family life.”
Others, like Dairylain Farms, a 500-cow dairy in Vale, Oregon, chose to go robotic more for business reasons. “We couldn’t find labor,” said owner Warren Chamberlain. “It made our decision to go this route pretty easy.”
Whatever the initial motivation, cows, it turns out, by all measurable standards, appear to love the systems.
“If you walk through the barn, the cows are calm and easy to be around,” Mizee said, “and they just do their own thing and really can express their potential.”
“The cow can eat, milk, drink, and do whatever she wants to do whenever she wants to do it,” Chamberlain said. “And the cows like it better. Our components came up, butter-fat protein came up, our milk-per-cow came up, and our health on the animals is better.”
Chamberlain also discovered another benefit since installing the systems in July 2016. “We are actually out with the cows more now that we were, and that is what we enjoy doing,” he said.
Robotics are just one of many ways that modern dairy farmers are evolving, sources said. Automated feeders, solar panels, methane digesters, GPS driven tractors and computerized irrigation are other examples of high-tech influence transforming this otherwise traditional industry.
More than any other single advancement, however, robotic milking systems appear to be generating the most buzz within the industry.
The systems do much more than milk cows. Through the use of software that reads radio frequencies from a sensor attached to a cow’s ear, or, in some cases, to a collar that cows wear, robotic milking systems identify unique characteristics of a cow when she enters the system’s milking area. Systems can then deliver a customized amount of feed based on a cow’s milk-production level, with cows that produce more milk receiving more of the high-protein, grain-based mixtures dairy farmers supply in the milking area than lower-producing cows.
Next, while cleaning a cow’s udder, the robot utilizes electronic mapping to locate a cow’s teats before milking the cow with suction-cup-like devices. When milking is complete, the system will re-clean the udder and spray a mist over the floor of the milking area, which signals the cow to move on and let the next cow enter.
Cows enter the milking area by pushing through a swinging gate. “It takes them a little while to realize that there is grain there, and to realize they can get some,” Chamberlain said. After that, left to their own devices, cows push through the gate on their own volition. “There is that feed incentive,” Sichley said, “and they want to get milked, as well.”
In addition to feeding and milking cows, robotic milking systems also analyze each cow’s milk for production elements, such as fat and protein content, and for warning signals of health issues. If the milk doesn’t meet strict quality standards, it is immediately diverted away from storage tanks.
Mizee also has an app on his smart phone that sends alerts when a cow is losing her appetite, resting more than usual, or engaging in other activities that indicate early stages of a health issue. The app, he said, helps him proactively treat cows before they get sick.
“It is all about getting to the point where you can be preventative and proactive, rather than treating for the condition,” Mizee said. “Probiotics and other preventative options can help you avoid using antibiotics.”
Not all dairies are equipped to operate robotic milking systems. For one thing, the cost for a system can be prohibitive. Among several competing brands of milking robots, all of which have unique characteristics, prices range from $175,000 to $250,000, with an expected payback of five to seven years.
Still, more and more dairies in recent years have come to realize the technology can work for them.
“Since we put ours in, in our area of Western Oregon and Western Washington, there has been basically one robot install going in almost all the time,” Mizee said. “We are getting to the point now where there are two or three going in at any one time.
“Part of that growth is that bigger farms have recognized the value of it. They are seeing value not only the labor savings, but in the fact that we are able to treat the cow better, and profit because of that. It is not just about quality of life anymore,” Mizee said.
“The fact that we are developing systems that are better for cows and better for people, I believe is pretty significant,” Mizee added. “That is going to keep generations farming, and that is going to keep our industry viable long into the future.”
