I have a seven year old cow that had a very large calf last Thursday night or early Friday morning. Her afterbirth was still attached to her as of late Sunday afternoon. I was told by experience neighbors that I might have to pull it before the it gets infected from heat and flys. I've done this only once in the past. When I tryed this time, it would not come out and broke in half with only about a foot still attached. The part where the flys and dirt was is now gone. Question: Should I continue to watch or should I get her in to the vet. She seems to be doing just fine eating and nursing the calf.
