Most folks will say there's not a lot you can do about ringworm, but since it is contagious to other cattle, dog, cats, humans and any mammal, I try to do something about it.
It also stays in wooden corral posts, etc., for about 2 years.
There may be some better meds and/or treatments available today. I haven't had an outbreak for many years. The last time we dealt with it, the vet said we could either leave it alone and it would go away when the sun came out (this was wintertime). Or, we could brush the infected area twice a day with a stiff bristled scrub brush until the areas bled, then apply a strong bleach solution. I would hate to do that to a cow's udder, though.
I think there may be some oral meds out now for livestock. I know there are some oral fungicides out for humans. Ask a vet.
Good luck to you. I know this is hard to deal with. Just remember to be careful, as you can catch it, too.
