Dairy farmers at the New York State Fair are trying out a new technology to help them determine when a calf is about to be born.
The big white tent at the end of the midway with a giant cow balloon in front is where fairgoers can watch the miracle of birth.
One cow delivered a healthy calf in front of hundreds of fairgoers. If they looked carefully, they would have noticed a bright green plastic contraption around the cow’s tale. It’s called a “moo-call.”
