Feedlots prepare for summer heat as cattle weights continue climbing

With summer weather approaching across the Midwest and Plains, cattle feeders are already preparing for the risk of heat stress in feedyards as heavier cattle and volatile weather patterns increase concerns heading into the hottest months of the year.

Even during years forecast to bring cooler temperatures or above normal rainfall, livestock specialists say short periods of extreme heat can still create major challenges inside feedlots. Heavy cattle nearing market weight are especially vulnerable because larger animals generate more body heat and often struggle to cool themselves during stretches of hot, humid weather.

Feedlot managers say preparation before summer arrives is critical because cattle performance can decline quickly once heat stress begins affecting intake and water consumption. Reduced feed intake during prolonged heat can slow daily gains, lower feed efficiency and increase the risk of digestive problems including acidosis.

Providing shade remains one of the biggest tools available for reducing heat related stress in feeder cattle. Direct sunlight can dramatically raise body temperatures, especially in black hided cattle. Shade structures also help keep pen surfaces cooler, reducing additional radiant heat during the afternoon hours.

Air movement is another important factor inside feedyards. Producers are encouraged to improve ventilation by removing temporary winter windbreaks, mowing heavy vegetation around pens and maintaining pen mounds that allow better airflow around cattle during hot weather.

Water demand can rise sharply during heat events, particularly in larger finishing cattle. Industry specialists say cattle nearing harvest weight may consume well over 30 gallons of water per day during extreme heat periods. Feedyards are being encouraged to inspect tanks, water lines and automated watering systems before summer temperatures arrive to avoid shortages during peak demand.

Feeding strategies may also change during hotter periods. Some operations shift feeding times later into the evening so peak digestion heat occurs overnight when temperatures are lower. Nutritionists also note that adding dietary fat sources can help maintain energy levels without creating as much internal heat during digestion.

Cattle handling practices are also adjusted during heat events. Many producers avoid working cattle during the afternoon and instead move processing activities into the early morning hours when temperatures are lower and cattle are under less stress.

Researchers continue studying additional heat mitigation practices including sprinklers, electrolyte supplements and feed additives designed to help cattle cope with extreme temperatures during the summer feeding season.
