COPING WITH SUMMER!

Heat stress occurs when a dairy cow’s heat load is greater than her capacity to dissipate the heat. Cows exhibit signs of heat stress in several ways, such as increased respiratory rates, water intake and sweating, decreased dry matter intake and slower rate of feed passage, decreased milk production and reduced reproductive performance. Ultimately, these can have an economic impact on any dairy. The severity of heat stress is measured by using a temperature humidity index (THI), which uses both temperature and humidity to calculate the theoretical level of stress to the animal.
