Increasing air temperature raises the water intake of most grazing animals. As temperature increases from 50 to 90 degrees Fahrenheit (F), daily water consumption by beef cattle will more than double. Contrary to popular belief, animals prefer to drink water that is near the normal rumen temperature of 100 to 102 degrees F, even in hot weather, according to the "Missouri Grazing Manual" published by Missouri Extension at the University of Missouri-Columbia. Attempting to cool water in the summer may actually lower water intake if the initial water temperature is not in excess of 95 degrees F. Warming water in the winter will increase water and feed intake of beef cattle
