I have one boar and two sows AGH's. Yesterday one of the sows was not as excited about feed time as usual. I was concerned, but apparently not concerned enough, cause this morning she was dead. She had a small amount of blood coming from her mouth and nose and from her anus. I lost another boar last year with a similar situation. I assumed that he had eaten something that had cut his throat (He hand only bled from the mouth). Now I am concerned for my other two piggies. Any ideas what it could be? They have not been given any chemical meds or anti-biodics. maybe I have to rethink that. Help please.
