Heat stress and its impact, and the 'cool' nutrient

Join us as Dr. Richard Kirkland, Global Technical Manager at Volac Wilmar, delves into the serious topic of heat stress. We answer the question, can rumen-protected fats influence a cow’s ability to withstand heat? And if so, how?
We also meet John Newbold, Professor of Dairy Nutrition at Scotland’s Rural College (SRUC), who reveals the significant risks of heat stress and how it could become even more common as global temperatures rise.
Watch this episode to discover:
• What causes heat stress in dairy cows and why it happens
• The issues that heat stress causes for productivity
• How effects of heat stress can be reduced using feed fat products
• Why diet formulation should be considered during periods of heat stress
This is the second of a 5-part series covering the topic, ‘Why Feed Fats?’. The series explores the positive impact of feed fats on everything from herd productivity to reducing heat stress and lowering methane emissions. Check back soon for the next episode!
