Cows sweat through their noses because that is where there sweat glands are. These are just a few of the only sweat glands a cow has.
Most likely it's an injury, from poking herself, or maybe got bit by something. If it's not an injury, and it could be internal bleeding, contact your vet ASAP to have a look at it.
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 lick them with their tongues.
No.
Through their noses.
They have no sweat glands and to keep cool they roll around on the ground and roll in their own excrement.
Only from their noses.

No, I don't think so. If they could sweat then they'd be drinking a heck of a lot of water. Most European cattle don't have the sweat glands in their skin like the Brahman-type cattle do. However they can sweat through their noses, as you often see beads of water on their noses when it is warm out.

Bos indicus cattle (like the Brahma) are capable of sweating through sweat glands in their skin. They sweat because it's a natural mechanism, like in humans, to cool off, to release excess body temperature when it is hot out or when they have been worked really hard. Bos Taurus cattle ("normal" cows), on the other hand, have to pant like dogs to regulate their body temperature, since they only have sweat glands on their noses and not the rest of their bodies.
Because of their fur, they can only sweat through their noses and bottoms of their feet. This is why they lose so much fur in the summer
it makes cows and frogs sweat.
Through their noses.
No. The production of milk is not related to how sweat is created and excreted via sweat-glands. The udder is not even made up of sweat glands in the first place!
Dogs do have sweat glands that are called apocrine glands. Dogs only produce sweat on areas not covered with fur, such as the nose and paw pads. Dogs also have sweat glands on their noses. Dogs don't sweat everywhere like us humans, but they do have sweat glands and they do sweat ! I hope this helps.
