Animal wearables, robotic milking machines help farmers care for cows

Wearable technology might still be a tough sell for humans. But farmers are embracing wearable devices for animals that help monitor livestock and allow robots to help care for them.

Wearable technology, like the under-performing Google Glass,might still be a tough sell for humans. But it seems to be catching on with farm animals.

More accurately, farmersare embracing wearable devices that help them monitor their livestock, such asGPS collars that track animals out in the pasture ore-pillsthat sit in animals' stomachsto measuretheirdigestion.

Other wearablesallow farmersto take advantageofhigh-tech innovations like increased automation.

For example, robotic milking pens that automatically milk cows that walk into themare quickly taking hold atfamily farms. Such robots operate with thehelp ofan e-tag clipped to the animal's earor an e-collarsnapped around an animal's neck. The wearableshelp the robot identify the animals and give each one personalized care, without the help of humans.

The industry websiteDairy Global estimates that within a decade, half of the farms in Western Europe, where the machines have been adopted more quickly than in Canada, will use suchautomated milking machines.

But there are signs they'recatching on in Canadatoo, with farmers like Clark Gourlay.

He has 75 cows at Morningstar Farm on Vancouver Island.Until now,he's been the kind of farmer who is up at the crack of dawn to milkcows.

But thenew robotic milking pen in his old barn has changed that.

Once thecow walks inside, a robotic arm does all the work.Lasers scan and map their underbellies, and a computer charts any physicalchanges.

"The robot identifies which cow they are," Gourlay said."It knows a whole lot of detail about that cowhow much milk she should be producing, how much she's been fed, where exactly her teats are.

"It gets to work, it cleans the teats off, and then it milks each teat out individually, and then disinfects her when she's done. The whole thing takes between six and nine minutes per cow."

E-collars help track animals' vitals

In its e-collar or e-tag, each cow carriesever-changing dataabout itssize, health,and information about its last milking, for example.

The devices can also track the amount and quality of milk produced, the frequency of visits to the milkingmachine, how much the animals eat, and even how active the animal has been. E-collars can even monitorvital signs, similar to the way a fitness tracker might for ahuman.

The technology also allows the cows to decide when it's time to be milked. That'sallowed thema new sense of freedom, Gourlay said.

"Nowthey just make decisions as individuals. When they want togo to the robot, they do. When they want to lie down, they do. When they want to go to the feed bunk, get water, they do."

Treating cows as individuals hasn't always been easy.Historically, automation in farming has been used in large agri-businessfarms where hundreds or thousands of animals are housed indoors in highly controlled environments.

Traditional automation worked best in situations where all animals were raised in what amounts to a factory system, but couldn't make decisions based on individual animals.

At small farms like Morningstar, wearables and robots have been key in givingeach cow a degree of autonomy, and allowing them tospend most of the day in a pasture eating grass.

Robot helps monitor milk quality

Gourlay said that's because new technology can make assessments and decisions that previously required humans.

"We spend a little more time on the computer, looking at the health of animals," he said.

"The robot checks every quart of milkevery time it milks that cow, that milk gets checked. If there is an issue, we see it right away on the computer. And if it's a significant issue, it doesn't even ask us, it just sends the milk down the drain."

Of course, thatmight be an issueif the robot makes the wrong call.

The cost of the milking machines, often around $200,000, can be another hurdle.

But Gourlaysaid the technology offers a lot of advantages, including cows thatarecalmer,because they no longer have to contend with being herded into a barn for milking multiple times a day.

And using the robotic milking machine means hegetsother tasks done more efficiently and gets to sleep in just a little bit longer.
