Went out a few weeks ago to feed and when checking cows noticed that one of them was rectally prolapsed. I put her in a pen inside of the barn and called the vet, by the time I got back to her she was back to normal and for over 4 weeks now not a sign of her prolapsing again. Just worried about calving time, vet said it must have been a perfect storm of calf positioning a full rumen and her straining to get up. He said not to worry about it unless it would continue to return. Didn't know if anyone else had any similar experiences and what the long term outcome has been.
