A Michigan dairy farm, SwissLane Farms is using fitness trackers for its cows.
The fitness trackers are designed to track the movement of the cows, as well as the cows health.
Tom Oesch is a dairy farmer at SwissLane Farms and says that the trackers are important.
The trackers are placed on the cows necks to track things like weight, daily steps, milk production, and how often the cows chew and spit.
"The more she's chewing, we know the more healthy her stomach is", said Oesch.
The trackers also help the farmers know how much milk a cow is producing and if a cow might need more attention.
The dairy farm says that its cows have been calmer, produced more milk, and been in the hospital less since the trackers were added.
