Temperatures will be in the mid-90s and higher this week, with elevated humidity. Be alert to heat stress symptoms in feedlot cattle.
- Evaluate 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.
- The Iowa Beef Center website has information and details on heat abatement strategies.
