No.
Cows sweat through their noses to help regulate their body temperature. Since cows don't have sweat glands, they rely on evaporative cooling through their nose and mouth to cool down when they are hot.
Through their noses.
Yes, but not as a waste gas during exhalation. Atmospheric air breathed in by the cow is ~21% oxygen. The cow can remove up to about 5% oxygen, so when exhaling the air from the lungs is about 16% oxygen.Another opinion:When exhaled, oxygen binds with carbon to form carbon dioxide, which is expelled as a "waste" gas. So in a way, yes cows do release oxygen when breathing, but not in the O2 form we are familiar with that is in the atmosphere and what plants expel during the process of photosynthesis.
Most cattle of European origin have their sweat glands in their noses. Brahman, Nelore, Guzerat, Afrikan and other long-eared loose-skinned breeds of the subspecies Bos taurus indicushave sweat glands in their skin and noses.

They use their noses to smell and their tongues to taste. They also use their eyes to see what other forage is in front of them (and to look out for danger as well.)
