After a cold winter and long cool spring, summer is here. Temperatures will be in the mid 90s this Friday, Saturday and Sunday, and with all the precipitation we have had, the humidity will be elevated as well. Feedlot cattle may not be acclimated to summer temperatures yet and the fast warm up this weekend may cause some heat stress issues.
Evaluate your cattle in the morning and again in the afternoon to make sure they are coping with the heat. Make sure cattle have access to plenty of fresh water and provide shade or sprinklers if possible. Pay close attention, as the rapid change in temperature may catch some at-risk cattle (cattle at end of feeding period or cattle with previous respiratory disease) dealing with excessive heat stress.
This early heat event is a good opportunity to make sure that your mitigation strategies will be functional for the rest of the summer. The Iowa Beef Center website has information and details on proper heat abatement strategies
such as shade and sprinklers.
