I know people have done it here (west central SD) where it can get rather brutal low temperatures. But they had access to very warm artesian water. Now most have rural water piped at least onto their ranches, so see little of it, and the town artesian well failed, so they also use the rural water now.
It sure would be a steady job, and time consuming depending on distance, numbers of cattle, etc. Comparing costs, it could possibly be less cost to bring the water to the pasture via pipe or well?
