Cattle Heat Load Scoring in Feedlots

Heat load scoring systems help feedlot operators assess and manage thermal stress in cattle during hot weather periods.

Key Facts

Heat load scoring evaluates panting, posture, shade use, and water consumption
Scores above 3 indicate moderate to severe heat stress requiring intervention
Respiratory rate above 80 breaths/minute signals heat stress in cattle
Black-coated cattle experience greater solar radiation absorption
Heat load scoring guides decisions on feeding times and misting systems

Welfare Considerations

Accurate heat load scoring enables timely interventions that prevent suffering, production losses, and mortality during extreme heat events.

What You Can Do

Encourage feedlots to implement standardised heat load scoring
Support provision of shade and water in hot weather
Advocate for welfare standards that require heat stress management plans
