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.

Your cows may not have a crystal ball, but monitoring technology used during the dry period may provide valuable information that can be used to predict the risk of potential health disorders that could affect lactation performance post-calving. Considering dry cows often are “out of sight and out of mind,” monitoring technology can fill the gap by keeping tabs on them 24-7.

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.

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.

The journey from pasture to plate is fraught with challenges, particularly during the initial receiving period when cattle are most vulnerable. The receiving phase, typically encompassing the first 45 days after cattle arrive at a feedlot, is critical for ensuring their health, well-being and subsequent productivity.

Summertime brings in the warmer weather and, with it, a different set of stressors for cattle. A number of factors can lead to stress in cattle, including fluctuations in temperature or adverse weather conditions.
