Ruminations #3 | Cooling the pressure: science-based strategies for healthier, more productive cattle
May 11, 2026 16:00 Europe/Copenhagen
Heat stress is no longer a seasonal inconvenience — it’s a structural challenge for modern cattle systems. Rising temperatures and humidity compromise feed intake, rumen function, immunity, wellbeing and ultimately milk yield, average weight gain and profitability. Addressing heat stress requires more than cooling strategies alone.
In this third edition of Ruminations, we take a holistic view of heat stress management, connecting cow biology and physiology, rumen health, nutrition, and on-farm practices into one integrated framework.
Join Prof. Cassandra Tucker PhD, one of the world’s leading experts in cattle welfare, for an insightful session on managing heat stress in beef and dairy systems. This webinar will explore how heat stress impacts animal health, behavior, and productivity—and how a holistic, science-based approach combining welfare, nutrition, and management can help producers feed smarter and protect performance under pressure.
Key learning objectives
Understand how heat stress affects cattle physiology, behavior, and productivity
Apply practical feeding strategies to support intake, rumen function, and resilience
Integrate welfare, nutrition, and management practices to mitigate heat stress effectively
Novonesis will donate USD 5 for each live webinar participant, up to a maximum total contribution of USD 3,000, to support the work of Kinder Ground. This donation is made by Novonesis and is not contingent on any purchase or business relationship.

Who should attend
Dairy nutritionists and consultants
Veterinarians
Dairy producers and herd managers
Anyone involved in decision-making around cow health, nutrition, and performance
Why attend
You’ll leave with practical insights and a clearer understanding of how nutritional solutions, combined with management, can strengthen the cow’s ability to cope with heat stress, supporting productivity and welfare when it matters most.
Join us for a science-driven discussion designed to help you think beyond single interventions and start managing heat stress as the complex biological challenge it truly is.
Dr. Cassandra Tucker PhD
Dr. Cassandra Tucker leads a research team focused on cattle behavior and welfare at UC Davis. She aims to understand the effects of housing and management systems from the animal's perspective. She also works as a consultant to help private, industry, and non-governmental organizations develop animal care standards as well as training and auditing programs. Through these activities, scientific information informs the day-to-day lives of cattle. She teaches courses about domestic animal behavior and animal welfare. Dr. Tucker is the Director of the Center for Animal Welfare and co-founder of the non-profit Kinder Ground, an organization that supports the farming community to improve animal welfare.

Dr. Oscar Queiroz graduated as an agronomist from the University of São Paulo in Brazil (2003) and earned his Ph.D. from the University of Florida in the USA in 2011. During his doctoral studies, he researched the impact of microbial additives and enzymes on the performance of dairy cows. Since 2015, he has been working at Novonesis (Chr. Hansen), initially serving as the Latin America Technical Manager and currently as a Senior Global Portfolio Manager for cattle probiotics, based in the Netherlands. Throughout his academic and professional career, Oscar has actively promoted the use of biosolutions to improve cattle performance, health, and safety. He has been involved in the development and launch of leading probiotics, such as Bovamine Dairy Plus, Defend Plus, and more recently, Bovacillus, Novonesis' global brand for cattle probiotics.
