According to wikipedia, "Although sweating is found in a wide variety of mammals, relatively few, such as humans and horses, produce large amounts of sweat in order to cool down."
Which is why it is not noticable.
I've never noticed a cow sweat, and our cows always have flies on them. I do not think its the sweat that attracts them, its the fact that cows are simply more dirty than goats. Cows lay down in manure and muck if it gets real hot, trying to cool. Goats do not.
I've seen cattle wet with I guess sweat, that's why cattle have flys on them all of the summer...goats don't
Flies are attracted to the saliva cattle sling over their backs when they attempt to shoo the flies away but I'm pretty sure cattle sweat a little too.
I didn't think goats had the ability to sweat so I started looking and according to the Merck Veterinary Manual - http://www.merckvetmanual.com/mvm/in...m/bc/70100.htm "Sweat glands (epitrichial [formerly apocrine] and atrichial [formerly eccrine]) are part of the thermoregulatory system. The evaporation of sweat from the skin is the primary cooling mechanism of the body for horses and primates and, to a lesser degree, pigs, sheep, and goats. There is some clinical evidence to suggest that limited sweating occurs in dogs and cats, and that it may have a minor role in cooling of the body. Dogs and cats thermoregulate primarily via panting, drooling, and spreading saliva on their coats (cats). However, cats will sweat through their paws especially when excited; this is most commonly seen as wet paw prints on surfaces, eg, examination tables."
I do remember feeling a slight dampness to my goats' coats when it's hot now that I think about it.
I do notice on really hot or humid day's that when I pet my goats they just have a slight dampness to there coats also, like Kim said. I just always figured it was sweat becuase it's hot.
I also spray them for flies & mosquito's so not such a problem with that. I've never seen the sweat dripping off them, just dampness.
I just think its amazing that goats and cows sweat at all. I mean, we have been upper nineties to the 100s in temps with extremely high humidity, for over a month now. It barely cools below 80 most nights. Its been really hard on the dairy cows, the flesh melts off them and they stand panting in the shade with drool pools under their mouths, yet I've never seen them sweat. Same for the goats, no signs of sweat at all, ever. So, it must take true extremes to push them to sweat!
Me on the other hand, I sweat like a sprinkler system!!
