I have a friend that has a calf about two weeks old. After it was born he noticed a patch of hair missing at the tail head and thought that maybe it had been skinned on a rock while it was being born. Now however the hairless patch has been extending up the spine. It now has a hairless streak down its back. He says the skin is kind of oozing in spots along the bare streak. He can't figure out what it is and the vet is a little stumped. Has anyone ever experienced this and if so what type of help can be given to the calf to help it recover? The calf is fairly healthey.....had some scouring early on.
