Why heat stress requires a nutritional response

Cooling strategies remain essential for managing heat stress, but nutrition can provide an additional layer of defense. Targeted nutritional strategies may help support the cow’s redox system and improve resilience during periods of thermal challenge.

Two nutrients highlighted in the webinar are selenium (Se) and methionine (Met), both of which play key roles in antioxidant systems and metabolic function. Ensuring adequate supply and selecting the optimal source of these nutrients can help maintain performance and health under stressful conditions.

Webinar topics

During this one-hour session, participants will explore:

• The connection between heat stress and oxidative stress
• Selenium’s role in antioxidant systems and why the source of Se matters
• How methionine influences antioxidant synthesis and supports health and performance during heat stress

Event details

• Date: Tuesday, May 19th
• Time: 4 PM CET / 10 AM EST / 7 AM PST
• Duration: 1 hour
• Format: 45-minute presentation + 15-minute Q&A

A timely topic for dairy production

Heat stress continues to represent a major challenge for dairy systems worldwide. Beyond reduced feed intake and milk yield, heat-driven oxidative stress can affect immune function, metabolic balance, reproductive performance, and long-term animal health.

By combining environmental management with targeted nutritional support, dairy operations can strengthen cow resilience and better protect performance during periods of heat load.
