TIPS TO HANDLE CATTLE AND HEAT STRESS by Jason Garrett, UT Extension Agent
Hot temperatures are here and beef producers need to be aware of the heat stress their cattle are under. When it’s extremely hot, cattle accumulate a heat load during the day and it lowers at night when cooler temperatures set in. Cattle cannot dissipate their heat load well during the day and rely on respiration to cool themselves being they don’t sweat effectively. Cattle under severe cases of heat stress will not perform well, be subject for sickness, decreased appetite, reduced breeding and milk production and in some instances death. Here are some tips to manage heat stress in your herd...
•Water consumption is driven by environmental temperatures. Make sure cattle have plenty of cool, fresh water.
•Cattle must have shaded areas they can access to reduce heat loads.
•Work cattle early in the morning, not during the day or evening when heat loads are at peak.
•Transport cattle early in the morning.
•Cull unruly or high headed brood cows. They generally are the first to show signs of heat stress, especially if having to pen or work them in hot weather.
•Control flies on cattle. Cattle fighting aggravating flies in extremely hot conditions don’t help with heat stress.
•Try not to wean calves in hot weather. This will add more stress to the cow, not to mention the calf.
•Remove bulls from herd after spring breeding season. This will prevent bulls from running open cows and building more heat stress. Also it’s a recommended practice.
•Watch cattle closely with past health problems.
•Dark colored and heavier cattle are more susceptible for heat stress.
•If cattle are confined, make sure the structure is well ventilated.
