Incredible Cows

From Wonkblog something I find incredible:

"There doesn't appear to be a cap yet on the projections," says Nigel Cook, a dairy expert at the University of Wisconsin's School of Veterinary Medicine. Even though cows are producing 23,000 pounds per year on average, some herds produce more than 30,000 per head -- and he's found exceptional animals that can produce between 45,000 and 50,000. If more cows can be brought up to that level, the line could keep moving upward for a good while yet. Unlike poultry, for example, the state of dairy science isn't anywhere near maturity.

 We were doing well to produce more than 10,000 lbs per year.
