Do cows sweat?

'Cows do sweat. Perspiration in the bovine kind, however, is not so noticeable as it is in horses and some other animals. In the case of the horse the seat glands are distributed widely over the skin and the animal sweats freely all over the body. But in the ox the sweat glands are less abundant and are most completely developed on the muzzle. Consequently a cow will sweat freely on the end of her nose, while what perspiration appears on her body is usually slight and almost imperceptible. Likewise the sweat glands of a hog are confined chiefly to the snout.'
