Cooling down hot cows

Description

Cows in California were sprayed down with water using nozzle type TK-0.75. The temperature of the cows' shoulders were measured after 3 minutes.

Usage

cows_small

Format

A data frame with 19 observations of 4 variables

cow

ID of the cow that was measured.

control

Shoulder temperature change (degrees Celsius) after 3 minutes when no water was sprayed.

tk_0_75

Shoulder temperature change (degrees Celsius) after 3 minutes using nozzle TK-0.75

tk_12

Shoulder temperature change (degrees Celsius) after 3 minutes using nozzle TK-12

Details

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. "
