how much do diary cows drink per day
These may be good guesses, but the answer is the modern dairy cow. A milking dairy cow drinks about 30 to 50 gallons of water each day. During periods of heat stress water intake may double. Water weighs 8.35 lbs/gal, so a milking dairy cow may consume as much as 420 (or more) pounds of water daily.hese may be good guesses, but the answer is the modern dairy cow.
