Managing Heat Stress in Cattle

The forecast for this weekend in highs in the 90’s with humidity to make the heat indexes likley in the 100’s.

For feedlot cattle, hot temperature for 2 or 3 days plus warm nights mean increased risk for heat stress. With a chance for rain on Thursday, humidity will increase making it difficult for heavy cattle to maintain thermo-neutral body temperature. Avoid working cattle this weekend, expect feed intake to drop and consider bumping the forage up. Mitigation strategies such as shade and sprinklers should be available.
