How much can milk can one cow produce?
Most of our cows produce about 10 gallons of milk per day, although some produce as much as 14 gallons a day. It is not unusual for a Holstein to produce about 25,000 lbs of milk per year. An average gallon of milk weighs 8.6 lbs, so that is 2907 gallons per year, since a cow produces milk for 305 out of 365 days each year.
