I just got this thread on Facebook....I have a cool story to share. We purchased a calf in June that had ringworm pretty bad on his face and a few here and there on his body. He was small but had great structure and was very good on his feet. I would say UGLY was correct. We tried lots of stuff to get him to "take off". Radale Tiner posted something about Vita Firm on FB so I looked it up and bought some Sure Champ. It cost 20.00 a 50lb bag and I fed as directed for 30 days. I also treated his ring worm with a topical. This calf didnt even look like the same one we brought home. He gained weight, his hair actually grew, and he ate everything. Button (our calf) has the shiniest black hair I have ever had on a steer and we live in West Texas where its HOT and the dirt is dry. I think it makes the feed more efficient, as we had to hold him for awhile because he actually outgrew calves three months older than him. This has been my experience with Vita Firm, I would recommend it.
