This summer’s extreme heat has been and continues to be brutal on Louisiana cattle.
When the temperature at night remains above 80 degrees, it’s really hard for cattle to cool down.
During an average year, August is the worst month for heat stress in cattle. But this year, high temperatures arrived early in June.
LSU AgCenter veterinarian Dr. Christine Navarre said this summer has been especially bad.
“Extreme heat exposure day after day for months on end is debilitating to production and the health of cattle,” she said.
According to Navarre, with these scorching temperatures, poor forage quality from the drought adds to the problem.
“Poor quality forage is harder for them to digest, which causes an even higher body temperature,” she said.
Cattle can dissipate heat in only four ways: radiation, convection, conduction and evaporation.
