Cows#

Cows in California were sprayed down with water using various nozzles. The temperature of the cows was measured at various body parts and time intervals. Descriptions of the variables are due to the authors of the study.

From the authors: “Dairies in the United States commonly cool cattle with sprinklers mounted over the feed bunk that intermittently spray the cows’ backs. These systems use potable water—an increasingly scarce resource—but there is little experimental evidence about how much is needed to cool cows or about droplet size, which is thought to affect hair coat penetration. "
