Also, since dairy cows tend to produce twice as much milk as beef or range cows do, dairy cows tend to drink more water on average than a typical beef cow would. So a 1000 lb lactating beef cow may drink around 15 to 20 gallons per day, whereas a 1000 lb lactating dairy cow may drink around 30 to 40 gallons a day. If a certain feed is higher in salt content than another, a bovine will drink more water to counteract the amount of salt that is found in the feed.
For beef, some estimates only consider drinking water for cattle, whereas other sources may consider the water needed to grow the food that the cow eats. The data here were taken from two sources: The Water Footprint Network. Water Content of Things: The World's Water 2008-2009, Peter Gleick, The Pacific Institute.
