Small increases in temperature and humidity can cause animals to expend more energy to stay cool, directly impacting growth rates and milk yields. By maintaining lower temperatures in the barn, evaporative cooling systems help animals stay comfortable, healthy and productive.

Sensor-based soaking delivers cooling when and where cows need it and uses cow activity to drive system response. When nozzles open because a cow is present and close when she leaves, cooling becomes both more effective and more efficient.

In our operations, holding area management and the proper use of a crowd gate play a crucial role in promoting a cow’s comfort and ensuring an optimal milk harvest experience during her daily parlor visits. While these tasks may seem straightforward, they require much more than just moving cows and running them through a parlor.

Working alongside external mitigation, nutrition interventions can help to reduce the impact of heat stress. Together, they help keep internal processes balanced and alleviate some of the stress from higher heat and humidity.

Even with all the available information, the challenges around heat stress still exist, and each summer we see cows struggling to maintain production and reproductive health through high temperatures and humidity across the U.S. While we know a lot about heat stress, there are still areas of learning to lean into and help support herds throughout the summer heat and humidity. 

Ventilation, cooling, bedding, lighting, feed and water access are the main foundations of cow comfort. Focusing on these aspects when designing and building your dairy barn will greatly enhance cow comfort, leading to better milk production, reduced health issues and overall improved welfare.

Heat stress has been estimated to cost the dairy industry $897 million, and one of the most effective methods to alleviate heat stress is to cool the cow directly using low-pressure soaking. This article will focus on feedlane soaking but will also touch on other areas where soaking is used.

Dairy cows are vulnerable to heat stress. As temperatures rise, so does a cow’s body temperature and respiratory rate as she pants to cool down. 

Choosing the right cooling system for a dairy farm will depend on various factors such as the climate in the region, the size of the farm and the cost of installation and maintenance.
