University of Missouri (MU) Extension specialists are urging cattle producers to take extra precautions as Missouri braces for another summer heat wave. While the first bout of extreme temperatures can strain livestock, it’s often the second that proves most dangerous. “Cattle may still be recovering from the first major heat event and be less resilient to future stresses,” said MU Extension State Specialist in veterinary toxicology and animal health Tim Evans. MU Extension climatologist Zach Leasor noted the danger goes beyond temperature alone. “Environmental factors such as high overnight lows, minimal cloud cover, little air movement and high relative humidity compound heat stress in cattle and other animals,” said Leasor. High dew points are also a concern. The dew point reflects the amount of moisture in the air, and as it rises, it becomes harder for cattle to cool themselves. Unlike other animals that sweat, cattle rely on panting to regulate body heat. Prolonged stress…
