STtalks #373 - Journey of Genetics Part 3: Mature Bull Management with Roger Breunig
In the third episode of our Journey of Genetics Series, Roger Breunig joins us to explain how the care and management of mature sires at the Fond du Lac facility directly impacts semen quality and long-term productivity. He details key management pillars, including single housing, age-based nutrition targets, body condition and weight monitoring, hoof-trimming protocols, and minimizing stress to protect libido and soundness. We discuss balancing market demand with bull longevity, optimal productive ages, and the lab check-in process immediately after collection, before sorting and freezing.
