Effect of Water Sprinkling with and without Air Movement on Cooling Dairy Cows

Dairy Research Department, Louisiana Agricultural Experiment Station, Baton Rouge

ABSTRACT

When cows were removed from sunshine, sprinkled with water and then subjected to a gentle breeze produced by a fan, they showed rapid changes toward normal body temperature and respiration rate. Shade alone showed a small change in that direction, while the fan alone and sprinkling without a fan were intermediate in their effects.

The results of this experiment give valuable information on how rain and wind as produced by nature tend to cool milking cows during summer months. The results also suggest the need for further experimental work on how mechanical sprayers and fans may be utilized economically during summer when nature is not producing wind or rain.
