WEBINAR ON: Targeted nutrition to protect dairy cows from heat-driven oxidative stress
Heat stress is one of the most underestimated challenges in dairy farming, with both immediate and long-term consequences for milk production, metabolic health, immune function, and overall cow resilience.
As temperatures rise, dairy cows experience physiological and metabolic responses that increase the production of reactive oxygen species (ROS). When antioxidant defenses are not sufficient to counteract this increase, heat stress can trigger oxidative stress and further amplify production losses and health risks. :contentReference[oaicite:0]{index=0}
Adisseo will host the webinar “Defending Dairy Performance: Targeted Nutrition to Mitigate Heat-Driven Oxidative Stress” on Tuesday, May 19th.
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.
Selenium and methionine are central nutrients for supporting antioxidant status and helping dairy cows cope with heat-driven oxidative stress.
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
The session will include a 45-minute technical presentation followed by a 15-minute Q&A.
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

This webinar is designed for dairy nutritionists, veterinarians, technical teams, producers, and industry professionals looking to improve heat stress resilience through science-based nutrition.
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.
Targeted nutrition offers an additional tool to help dairy cows maintain antioxidant balance, health, and productivity under heat stress conditions.
