About the Webinar

Genomic Selection for Heat Tolerance Is Here

Breedi, in partnership with Eurofins Genomics, is launching heat stress tolerance evaluations for dairy cattle — a new genomic tool designed for producers operating in hot climates across the Middle East, Latin America, and beyond.

To mark this launch, we’re bringing together two of the world’s leading scientists in heat tolerance genetics for a live online discussion. They’ll cover the science behind heat tolerance breeding values, the data and methods required to build them, and the real trade-offs between heat tolerance, milk production, and fertility.

Whether you’re a dairy producer, a genetics manager, or a breed association leader — this webinar will give you the knowledge to make informed decisions about breeding for heat resilience.

The Challenge

Heat Stress Is the Biggest Hidden Cost in Dairy

$10B+
Estimated annual global dairy losses from heat stress (IDF, 2025). Projected to grow significantly with climate change.
Up to 25–53%
Milk yield decrease during heat stress events — even in operations with advanced cooling systems.
Permanent
Unlike cooling infrastructure, genetic improvement for heat tolerance is cumulative, heritable, and costs nothing to maintain once bred into your herd.

Cooling systems help, but they are expensive, energy-intensive, and have limits. When temperatures hit 45°C+, no fan or sprinkler can fully protect a high-producing Holstein. Genomic selection for heat tolerance offers a fundamentally different approach — breed cattle that handle heat better from the inside out.

What You’ll Learn

90 Minutes That Could Change How You Breed

The Proof
How genomic breeding values for heat tolerance were built, validated in controlled experiments, and confirmed across continents.
The Method
What data you actually need (hint: you probably already have it) and how the models work in practice.
The Trade-offs
The real genetic correlations between heat tolerance, milk yield, and fertility — and how to balance them in a selection index.
The Debate
SLICK gene vs. genomic selection — silver bullet or one piece of the puzzle?
