Around 9.2 million cows are being milked on 110,000 farms in the United States.
More than 99% of all dairy farms are family owned and operated. Dairying has improved through the years. Today, one cow can produce the milk that it once took 10 cows to produce.
U.S. cows give an average of 2,000 gallons of milk per year. That's over 30,000 glasses of milk! Before milking machines were invented in 1894, farmers could only milk about 6 cows per hour.
Today, farmers use machines to milk more than 100 cows per hour. by Jared Crapps
