Friday morning I had a sow give birth to 11 piglets and 7 live and 4 stillborn. The four still born were born durning the following night. I belive she cleaned her self, I found four placenta sacks. This it Tuesday and she won't eat. She appears to be nursing still. She get up and drinks water but she won't eat. Any ideas what to do would be greatly appreciated. I call my vet but he says he doesn't know much about the pigs, just horses and cows.
