Farm Safety - Managing Heat Stress in Cattle  As temperatures
heat up during the summer, cattle producers need to assess the
heat stress that their cattle are under.  Compared to other
animals, cattle rely on respiration more than sweating to
dissipate their heat load.  Since cattle do not dissipate heat
effectively they accumulate a heat load during the day and
dissipate heat at night when it is cooler. During extreme
weather conditions with insufficient environmental cooling at
night, cattle will accumulate heat that they cannot disperse.
Typically physiological factors such as hide color, weight and
animal health predispose cattle to heat stress during the summer
months. To minimize heat stress, cattle producers can start now
initiating measures in their operation to assist cattle in
managing periods of hot, humid weather.    1.       Make sure
cattle have access to EXCESS WATER CAPACITY.  This means getting
extra water tanks into pens filled with fresh water.  During the
