Don't worry about those messy cows lol. I would hate for you to see some of ours. We just had 6" of snow melt in a day or so....now that is a mess! (thumbsup)
I couldn't figure out what that was on those cows, then I remembered what mud was.. It's so dry here we don't even get mud if we run the tank over. Sure wasn't like that last year here.
