I recentley bought a dairy calf from a big dairy and he told me it had juvenial ringworm and it would go away and the rest of my stock would not get it. WRONG!! All of the herd has it now cows and calves. I have tried everything..antibiotics, fungisides, tinactin, iodine, and spraying the corrals with bleach. If anybody has any help please let me know. The cows utter from feeding the babies is horrible. Any help would be appreciated. They are out in the sun all day in Alaska I just need to get ahead of the battle.
