When temperatures and humidity begin to rise in Wisconsin, keep a close eye on livestock. Temperatures in the high 80s and the 90s can cause problems, as well as a 75 degree F. day coupled with high humidity.
Heat stress can cause general discomfort, decline in animal performance and animal death.
If animals are kept outside, provide shade during hot weather. Heat from the sun is a major culprit in overstressed animals. Swine may sunburn during hot, sunny weather. Try to keep them out of the sun. Pasture wallows are also effective for sunburn protection and wet skin cooling.
