DairyTalk by Helmut Demmelhuber · Apr 28, 2026 · 19m

This episode is based on a technical article examining the role of the slick gene in dairy production under hot climate conditions and places its breeding relevance into context. It focuses on the ability of slick-coated animals to regulate body temperature more effectively, thereby mitigating the negative impacts of heat stress. This physiological advantage translates into improved feed intake, milk yield, and particularly reproductive performance. The discussion also outlines how breeding organizations are incorporating this trait into modern selection programs to enhance herd resilience…
