Securing the next generation of cows in the future stands as one of the most significant responsibilities of dairy farmers in the present. As we approach the summer season, it becomes crucial to address the challenges of heat stress, considering it can alter the future of our productions by affecting both our dry cows and calves. In this episode, Dr. Geoffrey Dahl sheds light on the impact of heat stress on dry cows and calves, the beginning of the journey towards ensuring the future of our dairy farms, including the long-term negative effects on the productivity of calves throughout their lives, the associated economic ramifications, the implementation of smart soaker systems, and the implications of heat stress on heifers.
