The average cow eats about 20 lbs. of hay, 20 lbs. of corn silage, 10 to 20 lbs. of corn, and 6 to 12 lbs. of supplements each day. If we ate as much as cows, we would have to eat about 360 cheeseburgers and drink about 400 to 800 glasses of water each day. That’s approximately 25 to 50 gallons of water, about the size of a bathtub of water. It probably helps that cows have a large stomach, with four compartments to digest their food. Plus, they have to keep up their figure, since the average cow weighs about 1,400lbs.

They also spend about 6 hours a day eating and another 8 hours chewing their cud. Most cows chew at least 50 times per minute, with more than 40,000 jaw movements in a day. All that chewing is done by 32 teeth, 8 incisors on the bottom front, 6 molars on each side on the top and bottom. The front of a cow’s grin is only a tough pad of skin.

All that eating helps the cows produce about 8 gallons of milk per day. To get to that amount, they are milked 2 to 3 times a day, 7 days a week, 365 days a year.
