It sounds like you have a case of worms, and it is probably decently progressed at this point. I would work to treat that ASAP. It should clear up quickly but you will want to do that well before the cows go to slaughter. I am not exactly sure of the time frame but the product you buy will indicate it on the box. It is best to deworm at least once per year to avoid this.

Looks like you got a case of mange or lice, and the contagious type. I would almost say ringworm but the pattern, lack of crusting and location of hair loss shows anything but ringworm (which is a fungal infection, not a parasitic one). You won't see any eggs because they are microscopic, so the only way to test if you do have a lice problem (or similar) is to send in a fecal sample to the local vet for analysis. Otherwise, a dewormer is definitely needed in this situation, Ivomec pour-on is always a go-to that often works.
