I have a 5 month old brangus heifer. Mom and pop are black she is red. I found her 2 weeks ago walking with her head down (like she was a bloodhound on a trail) I could tell she was exhausted . After observing her I found that she had rubbed her nose untiil it bled. Her ears were scaley and her eye lids had scales on them. Mucous and blood on her nose, and her rear around the tail and anus has lost all of the hair and is raw and bloody?? I gave her an antibiotic shot and sprayed the infected areas with a good medication, locked her up and have been grain feeding her. That was over a week ago and the symtoms have not improved that much. The nose and bleeding is better but the raw sore on her rear is not. Her eyes and ears are now peeling but it still looks like whatever it is, it's still there. got any ideas???
