Not sure what it is so I thought some of you might know.. Have a steer with thick crusty patches down his back. I've seen this before on their under belly or between their legs. It seems to itch pretty good cause you scratch it with a curry comb and the steer freezes and loves it. However, you scratch it off and the hair comes with it. It's not all small spots either. some areas are over 6 inches in diameter and some are smaller... Anyone know what this is?
