Heat stress is a leading cause of decreased production and fertility in Nebraska dairy cattle during summer. Some heat stress is unavoidable, but effects can be minimized if certain management practices are followed. Cattle automatically will reduce their feed intake during hot weather. Typically, early lactation cows are most swiftly and severely affected. This decreased forage intake alters the composition of the rumen and leads to acidosis and reduced fat content of milk. Feeding high quality forage during the summer will require the animal to reduce intake to maintain a balance ration. To decrease the risk of heat stress, increase the amount of water available, add misters, increase air exchange in the barn, and provide shade where possible.
