Abstract: As the dairy industry evolves, so do the strategies employed to maintain animal welfare, productivity and sustainability to accompany and maximize its progress. High temperatures and humidity can lead to heat stress, a critical issue affecting dairy cattle at all stages of life, including lactating cows, dry cows, growing heifers and preweaning calves. Effectively managing heat stress through interventions like mechanical cooling is essential to improve animal health and production efficiency, leading to overall farm sustainability. Mechanical cooling systems are among the most effective methods for managing heat stress in dairy cattle. While the fundamental principles remain similar, the timing and approach may vary depending on the climate characteristics, housing, age and physiological status of the animals. This presentation explores the implementation of cooling strategies, focusing on dry cows and preweaning calves. Our work underscores the significance of recognizing early signs of heat stress and implementing appropriate mitigation strategies, even for non-lactating cows.
