Ear Tags Much More than Cow ‘Bling’

Much of Kirsten Areias’ world is black and white.

It’s what the California dairy farmer sees when she looks out among the 300 or so dairy cows on her farm – black and white Holsteins.

“They’re not easy to tell apart,” she says.

This is why dairy farmers like Areias and others around the country give each calf an ear tag that dangles like an earring just moments after birth. Each tag has a number that serves as a lifelong identification of the cow.

Dairy Farmers Prioritize Keeping Cows Cool During Hot Summer Months

Cool cows are comfortable cows, which is why throughout the United States dairy farmers work hard to make sure their cows stay comfortable all year round.

Since summers in Hanford, Calif., often creep past 100 degrees, dairy farmer Brian Medeiros has continued to explore ways to help his cows stay cool.

Medeiros’s barns already featured fans and misting water jets, but recently he added new technology to find out what more he could do. Using infrared cameras, Medeiros found that some cows would get really hot during the day, while others would stay comparatively cool.
