We had a heifer calve sometime last night, woke up about 4am and saw a calf walking around on the barn cam. It looked likie she was trying to pass the afterbirth at a quick glance. The heifer wouldn't get up and I figured she was just played out so I threw the calf in the calf warmer box and went back in the house to try get some sleep. Went back out about 6 and she still hadn't passed what ever it was, just didn't look right a huge mass comming out so I called the vet. He came out and it was a prolaypsed uterus, he washed it up, stuffed it back in and sewed her labia a few stitches to prevent it from comming back out. He said about 25% of them still die after the repair, but figured she had a pretty good chance. I asked if she would have problems ever breeding back, he said most of them go on to recover fully and have a normal life if they survive the first 24 hrs. He also said it's fairy rare to encounter a prolapysed uterus, and to call right away if another one ever happens. The calf is doing very well and the heifer was up for about half an hour this afternoon, so far so good. Just a head's up if you have never experienced this or heard of it.
