Senninger sprinklers are also used by dairy producers for cattle cooling and udder washing. Wobbling sprinklers are the most popular choice for dairy producers due to their unique off-center rotary design and their ability to uniformly wet the entire herd.
Reducing heat stress is a major concern for dairy producers. As temperatures rise in a holding pen, intermittently sprinkling cows’ backs with water, and allowing the water to evaporate, increases cows’ natural ability to regulate their temperature.
This is done through a process known as evaporative cooling. A combination of sprinklers and fans running at 5 mph can help cows lower their body temperatures in as little as 30 minutes.
Some farmers hold cows in a sprinkler pen for pre-washing before they enter the milking parlor. Cows in sprinkler pens are sprayed with water for less than 5 minutes and then left to dry before being prepped for milking.
Pre-washing is particularly helpful for maximizing the effectiveness of the final wash and sanitation.
