Number 1995 is a very special cow. Every day, this Holstein, mostly black with a white cat-face-shaped spot on her forehead, sticks her head into a trough that measures the exact amount of feed she eats. She’s had her genome partially sequenced, and will soon get her breath checked for methane several times a day.
Number 1995 also happens to be J. P. Brouwer’s favorite. “I just like her character,” the Canadian farmer says. “It has nothing to do with how she looks. She’s a nice cow.”
