Here's the secret of the modern dairy farm: The essential high-tech advances aren't in machinery. They're inside the cow.
Take a cow like Claudia. She lives at Fulper Farms, a dairy farm in upstate New Jersey. Claudia is to a cow from the 1930s as a modern Ferrari is to a Model T.
In the 1930s, dairy farmers could get 30 pounds of milk per day from a cow. Claudia produces 75 pounds a day.
To appreciate a cow like Claudia, you have to know where to look.
