Swiss Cows Send Texts to Announce They’re in Heat
ZOLLIKOFEN, Switzerland — When Christian Oesch was a boy on his family’s hog farm, cellphones were a thing of the future. Now, Mr. Oesch tends a herd of dairy cattle and carries a smartphone wherever he goes. Occasionally he gets an SMS from one of his cows.
That is because Mr. Oesch, 60, who cares for a herd of 44 Red Holstein and Jersey dairy cows, is helping to test a device that implants sensors in cows to let farmers know when they are in heat. When that is the case, the device sends an SMS to the farmer’s phone.
