Cooling cows efficiently with water spray

Dairies use intermittent sprinkler systems to cool cows in warm weather, but little experimental work has been done to determine how much water is needed to achieve beneficial effects. A group of dairy scientists conducted a study at the University of California, Davis, to examine the effects of using low-flow sprinkler systems that cut water use for this purpose by nearly 75%. Their research is published in the current issue (June 2016) of the Journal of Dairy Science.
