A typical dairy cow produces 40 pounds of milk per day. The milk bottle was invented in 1884 by Dr. Hervey D. Thatcher, Potsdam, New York. Wisconsin and California lead the United States in milk production.
Dairy cows produce the most milk of any mammal in the world.
The average U.S. dairy cow produces 22.5 quarts of milk each day. That's about 16,000 glasses of milk per year - enough for about 40 people. The nation that achieves the highest milk production per cow is Japan. Japan's cows average 17,500 pounds of milk a year compared to the more than 16,000 pounds per cow per year produced by dairy cows in the United States. It takes 4.65 quarts of milk to make a pound of cheese.
