Welcome to Tech News briefing. It's Tuesday, April 1st. I'm Julie Chang for the Wall Street Journal. Dairy farmers are putting a little extra flare on their cows to help track their movements and possibly detect bird flu and other ill illnesses. Plus, copycat hotel sites that charge hefty fees have been popping up online. Our travel columnist will tell you how to avoid dubious resellers. Up first, Dairy farmers are putting smart devices like Internet connected collars, ear and leg tags on their livestock to better track the health of their cows. The devices could help detect diseases like bird flu, which has spread to cattle after wiping out millions of America's chickens over the past few years. Farmers say they hope the devices will help manage individual animals with less manual labor. WSJ Enterprise tech reporter Bel Lin has been following the story and she spoke with her colleague Victoria Craig. Here's their conversation.

A wearable device that helps farmers spot possible bird flu Just explain how this device works.

The device is typically a collar or an ear tag can also be a tag that goes on the legs or the tail of the cow. And it's sort of akin to a wearable that you and I would wear, maybe like a Fitbit or an apple watch. But for cows and for cattle, they are less designed to help you track your steps and figure out if your heart rate is where it's supposed to be on a workout, but more for farmers to figure out if their animals are in optimal health when they're read for breeding and if anything unusual is going on. It's been trained on a vast amount of information from number of cows, looking at their positions and movements and looking to see if there's even a deviation in whether or not the cows are acting the way that they normally are. Any deviation from that behavior indicates that something might be wrong. And then what's important to note is that the collars or the ear tags are not meant to actually identify diseases. It's meant to kind of say, hey farmer, you might want to take a look at your cow.

And it can be used not just for cows, but other animals too.
Bel Lin (2:33)
They can be used for other animals, but in terms of the overall livestock monitoring market, it's really cows that are in need of this technology because there's so many aspects of a cow's health that need to be tracked. What I most often hear is that cows are sort of like professional athletes. And so they're performing their best, they're giving us their best milk when they are at their optimal health. And that's why they need to be checked regularly.
