TLDR Combining genetic models helps improve heat tolerance in beef cattle.

The study highlights the effectiveness of combining breed-of-origin (BOA) with single nucleotide polymorphism (SNP)-based models to explore the genetic architecture of thermotolerance traits in beef cattle. This integration allows for a more accurate identification of breed-specific genetic contributions, thereby improving our understanding of thermoregulation in cattle. The findings offer practical insights that could be used to enhance heat resilience in beef cattle, potentially leading to better management and breeding strategies.
