One of our cows has foot rot. We tried the sulfur pills. Then went to LA 200. When she was still limping, we tried the Nuflor. It was really pretty wild. Within 30 seconds, every hair on her body was standing straight up. The skin on her face wrinkled. She was wobbly and acted as if the burn was intense. This lasted for about 5 minutes, then all was well. Has anyone experienced this? Was this a reaction to the antibiotic or was she trying to "faint" for lack of a better word?
