Have a 3 yr old Jersey cow used for a nurse cow. Just weaned three calves and put her in a pen by herself. Have been giving her grass hay, sweet cob, and calf mana twice a day to get some weight back on her. I recently noticed bald spots under her eyes and today noticed that the bald patches have spread under her jaw and neck. I am new at this game so what do you think? I should also mention that her pen got pretty sloppy for a while. It finally got so bad that I moved her out of it. Is this likely a fungus from the sloppy pen or perhaps feed related? Any help is greatly appreciated.
