I know the whole ringworm topic has been discussed on here a lot. I have a question a bought a specific treatment and if anyone has any experience with it. I have been fighting for a month or better and it has gotten better but not cleared up. A couple heifers that my kids showed this past summer has it right now and I am worried that my cows will get it and they are going to be calving next month and then their calves get it and I will be fighting it that much longer. So to get to my question I called my vet to see if he could prescribe anything and he gave me some ingestible iodine granules that you mix with salt and then feed an oz. per day per head. I am curious if anyone has used or heard of this and what success they have had. Thanks!
