I have a 5 week old potbelly pig who is bloated and in severe pain. No vet around here is open this time of night. She is trembling and sometimes her eyes roll back so i know she is hurting terrible. She is still on milk and also grower pellets. She has been bottle fed from day one, her other siblings all died. First time momma couldnt have cared less about the babies. She had powdered colostrum. 5 weeks old now. Had some diarrhea yesterday but i thought we had that under control and she was eating and drinking fine yesterday and this morning. And now this evening she is in very bad shape. Any suggestions?
