I have a 80 lb lamb that I can't seem to get rid of her diarrhea. My original thought was that she was having a grain overload, but I cut back on the grain and fed her just hay for a few days,gave her 30ml of pepto twice a day, and gave her some electrolytes. Unfortunately, that didn't work. I am pretty sure that it's not cocci because it hasn't spread to the others.Unless cocci isn't always contagious? Could heat stress be the cause of it? If so, what can I do to prevent it (we have fans that are on 24 hours)? I am still giving pepto and electrolytes, which seem to barely do anything for her. I'd love to hear other ideas. She doesn't appear to be sick apart from the diarrhea, but I still don't want to risk losing her.
