Livestock Stress

Pennsylvania is 5th in the U.S. in milk production and is one of the major agricultural contributions of the state. Cattle do not have sweat glands, they are unable to cool themselves through the evaporation of sweat on their skin. Instead, animals will try and wade in water, or breathe heavily (also called panting) in order to release added heat in their bodies.

When animals are under heat stress, they can stop eating, decrease in weight, stop milk or egg production and may not be able to reproduce.

Heat Stress is calculated using:

  • Wind
  • Temperature
  • Humidity
  • Solar Radiation
