The thermo-neutral range for cattle, in which they do not need to expend energy to keep their body temperature stable, is about 41°F to 77°F. When the temperature is above 77°F, especially with high humidity, cattle can have reduced production, particularly if nighttime temperatures stay over 70˚F.

Farmers may also see reduced fertility or loss of a pregnancy and increased metabolic and lameness issues. Combating heat stress in the herd requires an action plan to prevent heat stress and address heat stress-related issues.
