Cow with skin condition

[A.J.]

I know most likely the vet will
need to come out for diagnosis, but has anyone got an idea what this might be? I've never had one with spots like this on their skin. They are primarily down along her neck to her brisket and a few near her rear end. It's a cow I've had a couple years and I haven't brought any new stock in recently. My first thought is ringworm, since they started off as raised spots in her fur, then the fur fell off, but I wasn't sure. I haven't noticed her rubbing like they itch her. I tried Ultraboss pour on, an injectable wormer, and a pour-on dewormer/delicer at separate times and it didn't make a noticeable difference so I'm thinking it may be more fungal than parasites. She seems completely normal other than the spots.

Thanks all. ill try some of the treatments suggested. Will hopefully be able to get all the cows worked a little earlier than usual this spring. That and green grass will hopefully make a big difference.
