James, I raise Hereford cattle and have had something similiar to what you describe. The hair on the butt come off or hair around the eyes comes off. I have asked several vets about this, and some say this is a reaction to sunlight and lush forage. When I noticed this in one of my cows the forage was not lush at present, but followed lush spring grazing of wheat and clover mix. We may have treated with dexamethazone but the overall health was not affected and after several months the hair returned. Health diagnosis is dangerous on this board and your situation could be caused by something else.
