Cattle Heat Stress in Feedlot Systems

Heat stress in beef cattle feedlots is a significant welfare issue with growing urgency as global temperatures rise.

Key Facts

Feedlot cattle can experience heat stress above 25 degrees Celsius with high humidity
Heat stress causes reduced feed intake, panting, seeking shade, and in severe cases death
Heat load index tools help farmers assess risk and trigger mitigation responses
Shade provision and sprinkler systems reduce heat stress impacts significantly
Dark-coated cattle are more vulnerable to solar radiation than lighter-coated individuals

Welfare Considerations

Heat stress in feedlot cattle causes genuine suffering and in severe cases death. The combination of solar radiation, high ambient temperature, and the heat produced by rumen fermentation can push feedlot cattle into dangerous physiological territory. With climate change increasing both the frequency and intensity of heat events, proactive heat stress welfare management is becoming essential rather than optional.
