Most cattle do better in cold weather than hot weather. Their thick hide and hair helps keep them warm but makes it more difficult to dissipate body heat on a hot day. They don’t do well in extremely hot weather — especially if it’s humid — and can be at risk for heat stroke. Cattle have fewer sweat glands than horses or humans; sweating is not a great way for cows to cool themselves. Instead, they breathe faster — for more air exchange in the lungs; bringing in cooler air — or pant with their mouths open if they are very hot.
