How does a dairy that regularly sees temperatures over 110°F create pregnancies? Keeping cows cool. For Dickman and Sons Dairy, it really is that simple.

As warmer weather approaches, preparing fans and ventilation systems should be a top priority for dairy producers. Heat stress can begin at relatively mild temperatures, especially when humidity is high, and its impact on intake, reproduction and health can linger long after temperatures cool.

Dream of a high-performance sports car and a Corvette or Camaro may come to mind. In many ways, dairy cows are high-performance machines too. However, some dairy producers may still treat their top-performing “cowmaros” like their old, trusty farm trucks, which may not allow the cows to reach their full genetic potential. Just like a sports car, cows require maintenance and upkeep. By treating your cows like top performers instead of old farm trucks, you can increase cow productivity and maximize profitability.

Every dairy in the U.S. has experienced the effects of heat stress on dairy cows. There are a variety of management practices dairy producers can use to proactively address heat stress before it happens or support the herd to lessen the impact once it arrives. Yet with all that we know about managing and mitigating heat stress, there are still misconceptions.

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.

Being prepared for the heat will result in the least amount of stress on the cows and the people dealing with these animals. The environment where the cows reside is the critical area of the barn to evaluate. Keep the ventilation system, including doors and fans, set to where the system was designed. These actions will allow cooler heads (and cows) to prevail.
