AI helps identify heat-tolerant cows, improving dairy farming in a warming climate.
Researchers led by Dr. Anna Chlingaryan used AI to improve identification of heat-tolerant dairy cows, analyzing data from Australian farms including ruminal temperature, drinking behavior, milk yield, and climate.
They found heat stress impacts milk production and welfare starting at a THI of 75—higher than the prior threshold of 66—and developed a Hybrid AI-Based Model (HAIM) that boosts breeding accuracy.
The model, which integrates climate, production, and animal traits, identified heat-tolerant cows with 84% agreement to current methods but revealed a different 8% when prioritizing resilience over yield, offering farmers a more effective tool for sustainable dairy farming in a warming climate.
